Slipstreaming Windows XP To Create a Bootable Windows XP CD or DVD

Slipstreaming Windows XP To Create a Bootable Windows XP CD or DVD: -

Introduction

After a version of Windows is released, over time bugs are found or new enhancements are added by Microsoft. In order to fix these bugs and add these new enhancements, Microsoft will occassionally release a large update called a Windows service pack that contains all of bug fixes, enhancements, and new features created since Windows was released. Unfortunately, CDs that you have for Windows usually do not have these newer Service Packs already installed. This means that if you ever need to reinstall Windows with your CD, you will also have to deal with the timely task of reinstalling the service packs. To make matters worse, some of the fixes in these service packs are security related, and by not having them installed, your computer may be at risk from viruses or vulnerable to hackers. Therefore, not having these service packs installed after you install Windows could open yourself up to big security risks.

In order to resolve these types of issues it is possible to integrate the newer service packs over an an older copy of the Windows installation files. This allows you to install Windows with the service pack already installed so that you do not have to install them after the installation process. This process of integrating the newer service packs with older installation files is called slipstreaming. The goal of this tutorial is to walk you through creating a slipstreamed Windows installation CD or DVD that already contains Windows XP Service Pack 3. That way if you install Windows using this CD/DVD, your installation will already have these large updates installed, your computer will not be in as much danger, and you can just focus on installing the latest updates and the applications that you want on your computer.

First Steps

Before we can start the process of creating Windows install disc, we first need to gather some software. Below is a list of software that you will need to download and install, as well as CDs that you should have on hand in order to continue.

  1. An existing copy of Windows XP home, Professional, or Media Center. Unfortunately, for this step you can not use an OEM CD provided by your computer manufacturer (Dell, HP, etc).
  2. Nero Burning Rom or nLite if you do not have NERO
  3. ISOBUSTER
  4. Network installation copy of Windows XP Service pack 3
  5. A copy of your SATA drivers from your motherboard Web site if you have a SATA HDD that requires special drivers.
  6. A blank writable CD or DVD and a CD/DVD burner.

Once you have made sure you have all the software or media listed above, you should create a folder that will be used to store the files that will be written to the installation disc. For this tutorial, we suggest you create a folder on your C: drive labeled XPCD. Once the folder is created, please copy the entire contents of your XP CD to this folder.

Extracting the boot image

After you have completed copying your windows XP CD you will need to create a boot image by extracting it from your existing XP CD. To do this, have your XP CD inserted in your computer and start ISOBuster. When the program starts you will see a screen similar to the following. If you do not, change the selected drive so that it is pointing to the drive that contains your Windows XP CD.

IsoBuster screen shot

In the left hand pane you should select Bootable Disc. Click once on this Bootable Disc option, so it is selected, and you will now see a file called Microsoft Corporation.img in the right hand panel as shown in the image below.

Bootable Disc contents

Now right-click on the MICROSOFT CORPORATION.img file and select the extract MICROSOFT CORPORATION.img option as shown in the image below.

Extract bootable image from Windows XP CD

When it prompts you for the location where you would like to extract the file, save it to the folder you copied the contents of your XP CD earlier in the guide. If you are following the guide step-by-step, this folder will be C:\XPCD.

How to slipstream Windows Service Pack 3

Now that we have extracted the boot image we need to slipstream the service pack over the Windows files you previously copied into the C:\XPCD folder. Please make sure you have downloaded the network installation version Windows XP Service Pack 3 before continuing as we will need it during this step. When downloading the service pack, please download the files to the root directory of your C: drive.

Once the service pack is downloaded, you can slipstream the service pack using two methods. The first method is to use the command line and the second is to use the nLite program. The command line method will probably be a bit easier if you are comfortable with the Windows command prompt. Otherwise, use the nLite method described below.

Using the Command Line to slipstream the service pack:

Click on the Start Menu and then select Run. Then type command into the Open: field. Finally, click on the OK button. You will now be at a command prompt where you should type the following bolded lines. After each line, press enter on your keyboard as shown in the figure below.

CD\
C:WindowsXP-KB936929-SP3-x86-ENU.exe /integrate:C:\XPCD

Slipstream Service Pack 2 command prompt

If you are using an OEM Windows XP CD you will receive the following error. This error means that you cannot use this type of CD to create a slipstreamed installation and will not be able to continue with this tutorial.

This Service Pack cannot be integrated into a destination that also has integrated Software Updates.

Now that you are done slipstreaming the service pack using the command line. You should now skip to the section detailing how to slipstream your SATA hard drive drivers. If you are not using a SATA drive you can skip ahead to learn how to burn the DVD.

Using nLite to slipstream the service pack:

Download nLite and install the program. When the program starts, click on the Next button, and then at the next screen, select the Browse button to see a screen similar to the one below.

nLite locate windows install

Now select your Windows installation folder that we created at C:\XPCD and then click on the OK button. nLite will scan the directory and identify any previously installed Service Packs. When it has finished, click on the Next button. You will now be on a screen asking if there are any presets that you would like to use. Just click on the Next button again to continue.

You will now be on the Task Selection screen. Simply click once on the Service Pack button so that the circle becomes green as shown in the image below.

Select service pack

Now that it is selected, click on the Next button. You will now be prompted for the location of your service pack installation file that you downloaded earlier as shown in the image below.

Select service pack file

Browse to the service pack file and select it. Then click on the Open button. file. Once you click on the open button, nLite will automatically slipstream the service pack into your C:\XPCD folder. When it has finished, click on the Next button, and then at the next screen, click on the Finish button to close the program.

You should now continue to the section detailing how to slipstream your SATA hard drive drivers. If you are not using a SATA drive you can skip ahead to learn how to burn the DVD.

How To slipstream SATA Drivers Using nLite

If you have not already installed nLite, you will need to download and install the program first. Next, you will need to download your SATA drivers from your motherboard or computer manufacture's web site. In our example, I will be using VIA raid drivers from Biostar. Once the SATA drivers have been downloaded, you should extract them to a folder on your hard drive. In our example, we have extracted the drivers into the C:\SATA Driver folder.

Now that everything is prepared you should start the nLite program. When the program starts, click on the Next button, and then at the next screen, select the Browse button to see a screen similar to the one below.

nLite locate windows install

Now select your Windows installation folder that we created at C:\XPCD and then click on the OK button. nLite will scan the directory and identify any previously installed service packs. When it has finished, click on the Next button. You will now be on a screen asking if there are any presets that you would like to use. Just click on the Next button again to continue.

You will now be on the Task Selection screen. Simply click once on the Drivers button so that the circle becomes green as shown in the image below.

Select Drivers in the Task Selection screen

After selecting Drivers, you should click on the Next button. You will now be at the Drivers screen. You should now click on the Insert button and then select the Multiple driver folder option so you can include all of the drivers for your specific operating system.

Select multiple driver folder

You will now be prompted for the folder where your extracted drivers are. You now want to browse to this folder, and when there, locate the correct folder for your Operating system. In our case it is the x86 directory since I am using 32bit Windows XP Pro.

You should now select the folder, and then press the OK button. nLite will now automatically install the drivers contained in both subdirectories. You will now see a screen showing the available drivers found in these folders. You should click the All button to select all drivers for your system and then press the OK button.

NOTE: If there are drivers for other versions of windows, for example Vista or 64 bit drivers, do not install them as it will cause file load errors. If you do select them, nLite will notify you of the problem.

When done selecting the correct drivers, click on the OK button.

A new screen will appear asking what driver mode you would like to select. At this screen, you should select the Textmode Driver as shown in the image below.

Textmode driver

If multiple are listed in the Textmode integration options box, select the appropriate driver for your operating system. The OK button will now become available and you should click on it. Do this same routine for for each and every driver that you are installing.

After selecting Textmode Driver you will be at a page listing all the drivers that will be installed. You should click on the Next button and then click on the OK button when it asks if you want to start the process. Your SATA drivers will now be integrated into your Windows files folder. When the process has finished, click on the Next button and then the Finish button.

You are now ready to burn the Windows files to your a bootable DVD. If you will be using Nero to create this DVD, then you can continue to the next section. Otherwise, you can skip ahead to instructions on how to use the free nLite utility to create your DVD.

Burn a bootable CD or DVD Using Nero

Please note that older versions of NERO may not use the same steps as what are outlined in this guide. These steps were created for use with Nero 7 and above.

If you own Nero, then start the Nero Burning ROM program. Once started, if you do not see an option labeled Make Bootable DVD, as shown in the image below, you will need to enable the advanced user settings.

Nero Burning ROM

To start, select the Make Bootable DVD option. On the next screen you will be asked to select a Boot image. You should browse to the folder where you saved the Microsoft Boot image that you extracted using Isobuster in previous steps and select it. Please note, that by default Nero will be looking for a file with a .IMA extension, so you will need to change the file type to All Files (*.*) in order to select the MICROSOFT CORPORATION.img boot image. This is shown in the figure below.

Select Boot image in Nero

You should now click on the Boot tab and put a checkmark in Enable expert settings. Then change Kind of Emulation to No Emulation. Then change the Number of loaded sectors to 4. When done your screen should look similar to the image below.

Change Boot options in Nero

Under the ISO tab, you should not have to change any settings. Just click on the tab to make sure it is configured as shown in the image above. If you have an older version of Nero you will not have the option Do not add the ';1' ISO file version extension under the Relax restrictions category.

ISO Option tab in Nero

Now click on the Label tab. We recommend changing the labels on your completed CD or DVD so that they match your Windows CD. To do that Select Manual and then enter the labels into the ISO 9660 and Joilet fields. For Windows XP Pro you should enter WXPCCP_EN. For Windows XP Home you should enter WXHCCP_EN. An example of this is shown in the image below.

Label options in Nero

Now click on the New button to open the file browser as shown in the image below.

File browser window in Nero

In the right hand pane you will navigate to your slipstreamed location, C:\XPCD, and left-click once on it to select it. Then select all of the files in the right-hand pane and drag them into the left-hand pane. When this is completed, click on the Burn button in the top menu bar. Nero will create the bootable CD for you and you will now have a Slipstreamed Windows XP SP3 CD or DVD!

Burn a bootable CD or DVD using nLite

If you have not already installed nLite, you will need to download and install the program first and then start it.When the program starts, click on the Next button, and then at the next screen, select the Browse button to see a screen similar to the one below.

nLite locate windows install

Now select your Windows installation folder that we created at C:\XPCD and then click on the OK button. nLite will scan the directory and identify any previously installed Service Packs. When it has finished, click on the Next button. You will now be on a screen asking if there are any presets that you would like to use. Just click on the Next button again to continue.

You will now be on the Task Selection screen.

Select Bootable ISO

On this screen select the Bootable ISO option as shown in the image above and then click on the Next button.You will now be at the Bootable ISO screen that will look similar to the image below.

nLite Bootable ISO screen

If the screen above does not look exactly like what you see on your computer, do not be concerned as we need to make some changes first. First change the Mode option to Direct Burn. Then, for the Label field we recommend using the same label that was on your original Windows CD. For Windows XP Pro you should enter WXPCCP_EN into the Label field. For Windows XP Home you should enter WXHCCP_EN into the label field. Next, make sure your CD/DVD burner is selected in the Device menu. Last, but not least, change the Burn Speed to 8X in order to get a reliable burn.

When you have finished configuring these settings, we need to specify our boot image. To do that, change Boot Sector to custom and a window will open asking you to locate your boot sector. You should browse to the folder where you saved the Microsoft Boot image that you extracted using Isobuster in previous steps and select it. Please note, that by default nLite will be looking for .bin or .dat files, so you will need to change Files of type to All Files. Once you do that you will be able to select the MICROSOFT CORPORATION.img boot image as shown in the image below.

Select boot image in nLite

Once you have changed all of your settings and selected your boot image, we are ready to create the Windows installation media. To start this process, click on the Burn button. A confirmation prompt will appear asking if you are sure you want to burn the content to the media. You should click on the Yes button to start the process. nLite will now start preparing the content that will be copied to your media. This may take some time, so please be patient. When it has finished preparing the files, nLite will start writing them to your media as shown in the image below.

Burning your Windows CD with nLite

Please be patient while the files are written to your media. When it has finished, you will see a message stating the written files were verified successfully. You can then click on the Next button and then click on the Finish button to close nLite.

You now have a Slipstreamed SP3 CD or DVD!

Conclusion

Now that you have learned how to make a bootable Windows installation disc you can make an install or reinstall process much quicker and secure. Using a disk like this you can now install Windows XP and be at a high patch level so that your freshly installed operating system is less vulnerable to malware and hackers. This also enables you to go to locations where there is not a lot of bandwidth and install Windows with all of the latest service packs installed so you do not have to wait for a long time while the service pack downloads. If you have any questions regarding this process, or tutorial, please feel free to ask us in the Windows XP forum.

What is the Recovery Console?

The Recovery Console is a special boot up method that can be used to help fix problems that are preventing your Windows installation from properly booting up into Windows. This method allows you to access the files, format drives, disable and enable services, and other tasks from a console prompt while the operating system is not loaded. It is suggested that the Recovery Console is to only be used only after Safe mode and the other standard startup options do not work. I feel that the Recovery Console is also useful in other situations such as removing malware files that start in both Safe mode and Standard Mode and thus not allowing you to delete the infection.

This tutorial will guide you through the installation of the Recovery Console and how to use it. For those who are familiar with DOS or the command prompt, you will find the Recovery Console to be very familiar. For those who are not comfortable with this type of environment, I suggest you read through this primer in order to get familiar with this type of interface:

Introduction to the Windows Command Prompt

How to install the Recovery Console to your hard drive

I recommend that you install the Recovery Console directly onto your computer so that if you need it in the future, it is readily available. The Recovery Console only takes up approximately 7 megabytes so there is no reason why you should not have it installed in case you need it.

To install the Recovery Console on your hard drive, follow these steps:

  1. Insert the Windows XP CD into your CD-ROM drive.

  2. Click the Start button.

  3. Click the Run menu option.

  4. In the Open: field type X:\i386\winnt32.exe /cmdcons , where X is the drive letter for your CD reader, and press the OK button. An image of this step can be found below:




  5. After pressing the OK button a setup window will appear similar to the one below.




    Simply press the Yes button to continue with the installation of the Recovery Console. The setup program will then attempt to do a Dynamic Update to make sure you have the latest files as shown below.






    Simply allow it to continue and then when it is finished, you will be presented with a screen similar to the one below telling you so.




  6. Press the OK button and remove the CD from your computer.

Now when you start your computer you will have an option to start the Recovery Console.

How to start the Recovery Console

To start the Recovery Console when it is installed on your hard drive you would do the following:

  1. Reboot your computer and as Windows starts it will present you with your startup options as shown in the figure below.





  2. With the arrows keys on your keyboard select the option listed as Microsoft Windows Recovery Console and press the enter key on your keyboard.

  3. The Recovery Console will start and ask you which Windows installation you would like to log on to. If you have multiple Windows installations, it will list each one, and you would enter the number associated with the installation you would like to work on and press enter. If you have just one Windows installation, type 1 and press enter.

  4. It will then prompt you for the Administrator's password. If there is no password, simply press enter. Otherwise type in the password and then press enter. If you do not know your password then see this.

  5. If you entered the correct password you will now be presented with a C:\Windows> prompt and you can start using the Recovery Console.

  6. Proceed to How to use the Recovery Console.

To start the Recovery Console directly from the Windows XP CD you would do the following:

  1. Insert the Windows XP cd in your computer.

  2. Restart your computer so you are booting off of the CD.

  3. When the Welcome to Setup screen appears, press the R button on your keyboard to start the Recovery Console.

  4. The Recovery Console will start and ask you which Windows installation you would like to log on to. If you have multiple Windows installations, it will list each one, and you would enter the number associated with the installation you would like to work on and press enter. If you have just one Windows installation, type 1 and press enter.

  5. It will then prompt you for the Administrator's password. If there is no password, simply press enter. Otherwise type in the password and then press enter. If you do not know your password then see this.

  6. If you entered the correct password you will now be presented with a C:\Windows> prompt and you can start using the Recovery Console.

  7. Proceed to How to use the Recovery Console.


Remove the prompting of a password

When the Recovery Console starts it will ask for your Administrator password before continuing. In many cases when you have XP pre installed on your computer the Recovery Console will not recognize your Administrator's password. In these situations it is possible to edit a registry setting so that the Recovery Console does not ask for a password. This setting works on both Windows XP Home and Pro editions.

To change this setting do the following:

  1. Click on the Start button.

  2. Click on the Run option

  3. Type regedit.exe in the open field and press the OK button.

  4. Navigate to the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsNT\CurrentVersion\Setup\RecoveryConsole

  5. Change the value of SecurityLevel value to 1

  6. Close regedit

  7. Reboot your computer.

Now the Recovery Console will no longer ask for a password.


How to use the Recovery Console

Though the Recovery Console looks similar to a standard command prompt it is not the same. Certain commands work, while others do not, and there are new commands available to you. There is no graphical interface, and all commands must be entered by typing them into the console prompt with your keyboard and pressing enter. This may be confusing for those who are not familiar with this type of interface, but after doing a few commands it does becomes easier.

The following is a list of the available commands that you can use in the Recovery Console. When using the recovery console you can type help followed by the command to see a more detailed explanation. For example: help attrib.

Command
Description


Attrib Changes attributes on a file or directory.
Batch
Executes commands that you specify in the text file, Inputfile. Outputfile holds the output of the commands. If you omit the Outputfile parameter, output appears on the screen.
Bootcfg Allows you to modify the Boot.ini file for boot configuration and recovery.
CD (Chdir) Change directory. Operates only in the system directories of the current Windows installation, removable media, the root directory of any hard disk partition, or the local installation sources.
Chkdsk Checks a disk for drive problems or errors. The /p switch runs Chkdsk even if the drive is not flagged as dirty. The /r switch locates bad sectors and recovers readable information. This switch implies /p. Chkdsk requires Autochk. Chkdsk automatically looks for Autochk.exe in the startup folder. If Chkdsk cannot find the file in the startup folder, it looks for the Windows 2000 Setup CD-ROM. If Chkdsk cannot find the installation CD-ROM, Chkdsk prompts the user for the location of Autochk.exe.
Cls Clears the screen
Copy Copies one file to a target location. By default, the target cannot be removable media, and you cannot use wildcard characters. Copying a compressed file from the Windows 2000 Setup CD-ROM automatically decompresses the file.
Del (Delete) Deletes one file. Operates within the system directories of the current Windows installation, removable media, the root directory of any hard disk partition, or the local installation sources. By default, you cannot use wildcard characters.
Dir Displays a list of all files, including hidden and system files.
Disable Disables a Windows system service or driver. The variable service_or_driver is the name of the service or driver that you want to disable. When you use this command to disable a service, the command displays the service's original startup type before it changes the type to SERVICE_DISABLED. Note the original startup type so that you can use the enable command to restart the service.
Diskpart Manages partitions on hard disk volumes. The /add option creates a new partition. The /delete option deletes an existing partition. The variable device is the device name for a new partition (such as \device\harddisk0). The variable drive is the drive letter for a partition that you are deleting (for example, D). Partition is the partition-based name for a partition that you are deleting, (for example: \device\harddisk0\partition1) and can be used instead of the drive variable. The variable size is the size, in megabytes, of a new partition.
Enable Enables a Windows system service or driver. The variable service_or_driver is the name of the service or driver that you want to enable, and start_type is the startup type for an enabled service. The startup type uses one of the following formats:
SERVICE_BOOT_START
SERVICE_SYSTEM_START
SERVICE_AUTO_START
SERVICE_DEMAND_START
Exit Quits the Recovery Console, and then restarts the computer.
Expand Expands a compressed file. The variable source is the file that you want to expand. By default, you cannot use wildcard characters. The variable destination is the directory for the new file. By default, the destination cannot be removable media and cannot be read-only. You can use the attrib command to remove the read-only attribute from the destination directory. The option /f:filespec is required if the source contains more than one file. This option permits wildcard characters. The /y switch disables the overwrite confirmation prompt. The /d switch specifies that the files will not be expanded and displays a directory of the files in the source.
Fixboot Writes a new startup sector on the system partition
Fixmbr Repairs the startup partition's master boot code. The variable device is an optional name that specifies the device that requires a new Master Boot Record. Omit this variable when the target is the startup device.
Format Formats a disk. The /q switch performs a quick format. The /fs switch specifies the file system.
Help If you do not use the command variable to specify a command, help lists all the commands that the Recovery Console supports.
Listsvc Displays all available services and drivers on the computer.
Logon Displays detected installations of Windows and requests the local Administrator password for those installations. Use this command to move to another installation or subdirectory.
Map Displays currently active device mappings. Include the arc option to specify the use of Advanced RISC Computing (ARC) paths (the format for Boot.ini) instead of Windows device paths.
MD (Mkdir) Creates a directory. Operates only within the system directories of the current Windows installation, removable media, the root directory of any hard disk partition, or the local installation sources.
More/Type Displays the specified text file on screen. More will display a text file one page at a time, while Type displays the entire text file at once.
Rd (Rmdir) Removes a directory. Operates only within the system directories of the current Windows installation, removable media, the root directory of any hard disk partition, or the local installation sources.
Ren (Rename) Rename a file or directory. Operates only within the system directories of the current Windows installation, removable media, the root directory of any hard disk partition, or the local installation sources. You cannot specify a new drive or path as the target.
Set Displays and sets the Recovery Console environment variables.
Systemroot Sets the current directory to %SystemRoot%.


Deleting the Recovery Console

Warning: To remove the Recovery Console you need to modify the Boot.ini file. Modifying this file incorrectly can prevent your computer from starting properly. Please only attempt this step if you feel comfortable doing this.

To remove the Recovery Console from your hard drive follow these steps:

  1. Double-click on My Computer and then double-click on the drive you installed the Recovery Console (usually the C: drive).

  2. Click on the Tools menu and select Folder Options.

  3. Click on the View tab.

  4. Select Show hidden files and folders and uncheck Hide protected operating system files.

  5. Press the OK button.

  6. Now at the root folder delete the Cmdcons folder and the Cmldr file.

  7. At the root folder, right-click the Boot.ini file, and then click Properties.

  8. Click to clear the Read-only check box, and then click the OK button.

  9. Click on Start, then Run and type Notepad.exe c:\boot.ini in the Open: field and press the OK button.

  10. Remove the entry for the Recovery Console. It will look similar to this:
    C:\cmdcons\bootsect.dat="Microsoft Windows Recovery Console" /cmdcons

    Make sure you only delete that one entry.

  11. When you are done, close the notepad and save when it asks.

  12. Right click again on the boot.ini file and select Properties.

  13. Put a checkmark back in the Read-only checkbox and then press the OK button.

The recovery console should now be removed from your system.

How to Manually Repair Windows 7 Boot Loader Problems

How to Manually Repair Windows 7 Boot Loader Problems


If you’re having boot problems on your Windows PC, it’s often helpful to repair the MBR (Master Boot Record) to restore the Windows 7 boot loader—and you can do it easily from the Windows installation disc.

This is generally most useful if you’ve broken something and there’s a boot loader error, or if you have made the mistake of installing an older version of Windows on the same PC that already has Windows 7 which wipes out the boot loader.

Note: If your PC starts booting into Windows but fails, you should probably try using Safe Mode instead.

Boot From the Windows Install Disc

The first thing you’ll need to do is boot off the install disc, and then click through until you see the “Repair your computer” link in the lower left-hand corner.

image

You’ll need to choose the correct installation of Windows and then click the Next button.

image

And then you’ll get to the System Recovery Options screen, where you can get to the Command Prompt.

image

Repairing the Master Boot Record

If you want to restore the master boot record, you can simply type in the following command:

bootrec /fixmbr

You can also write a new boot sector onto the system partition with this command (which is often more useful):

bootrec /fixboot

And of course, if you just use bootrec /? you’ll be able to see all the options.

image

This is the same way that we fixed the “BOOTMGR is missing” error when trying to boot up Windows 7 or Vista.

Replacing the Windows XP Bootloader with Windows 7

If you’ve managed to install XP on the same PC that you already had Windows 7 on, you’ll noticed that you can’t boot into Windows 7 anymore. You can use this command to fix that and restore the Windows 7 bootloader:

bootsect /nt60 all

Depending on the partition that you’ve installed, you might need to substitute the drive letter instead of “all”.

image

Note: if you want to restore Windows XP back to the menu, you can open up a command prompt in Windows 7 and run this command:

bcdedit /create {ntldr} -d “Windows XP”

image

Using the Automated Startup Repair

Of course, all this command-line stuff is probably not necessary in most cases. You can usually just use the Startup Repair option from the Recovery menu…

image

It’ll check for problems and probably fix them. If not, then you can always use the command prompt.
