How to Install XP after Vista and Fix the Bootloader

22 posts in this topic

To install an older Windows operating system on a computer running Windows Vista, use the following procedure.

  1. Install the previous version of Windows, e.g. XP or 2000
  2. Log on to the older operating system and restore the latest boot manager by running the following.
    bootsect.exe -NT60 All


    bootsect.exe might be in your boot folder of active partition. If not there, then it's on your Vista DVD in boot folder.

  3. Create a BCD entry for the older operating system by specifying the following. Bcdedit.exe is located in the \Windows\System32 directory of the Windows Vista partition. Description is the description of the new entry for the older operating system.
    Bcdedit /create {legacy} /d “Description”
    Bcdedit /set {legacy} device boot
    Bcdedit /set {legacy} path \ntldr
    Bcdedit /displayorder {legacy} /addlast


  4. Restart the computer in order for the changes to take effect.

Just curious, how would XP see Vista when you try to install it? Will it recognize it and give you the option of installing on a drive other than C?

You choose where you want XP installed. Choose a drive other than your Vista drive.

You can use a third party program like EasyBCD or VistaBootPro, but apparently, behind the screens, both programs run this command to restore the bootloader. Go to your EasyBCD installation folder and you'll find bootsect.exe.

Also, if you want to revert back to XP's bootloader, then run

bootsect.exe -nt52

.

I had no problem at all installing XP alongside a pre-installed Vista on my HP nc6320 laptop. I used EasyBCD successfully. On the other hand, I get stuck right from the start, when I try to do the same thing on a Dell Inspiron 6400.

When I reach the point where XP installer asks where the XP partition should be located and I select an unallocated area (same problem appears even if I create and format an empty partition beforehand and select it), I get the following error message : “To install Windows XP on the selected partition, installation program must copy certain boot files on Disk 0 with ID 0 on bus 0 on atapi [MBR]. However, this disk does not contain a partition compatible with Windows XP”.

I don’t know whether this has to do with the SATA disk. On the HP, I disabled SATA Native Support in the BIOS and everything went fine. In the Dell Bios, I found no equivalent option.

How can I create a “compatible partition” ?

How did you create your partition beforehand? Did you use Vista? If so, partitions created by Vista are no longer compatible with Windows XP.

See this: Vista's New Partitioning Rules.

It's best to create you partition with a third party utility. I would prefer using BartPE with Sherpya's XPE plugin to use XP's disk management console to do it.

However, I don't understand why you can't install on unallocated space. During XP setup, trying deleting the unallocated space and create a new partition and use XP to format it as NTFS it you are able to.

Use Easy BCD and forget about to change anything manually.

I used Acronis Disk Director to create the partition. This was done under Vista. Maybe I should use the Acronis Boot Loader and create the partition from this "neutral" environment.

What should I use EasyBCD for in this situation?

EasyBCD has nothing to do with the partitions you are creating.

Just wanted to mention I have the OEM Vista64 version and bootsect.exe is not included on the install disc nor could I find it on my vista partition. I had easybcd installed so I had a copy but it wouldn't run in the Vista64 recovery CLI console. There is another utility on that is available on the recovery console called bootrec that has options to fix the mbr and other things.

Just wanted to add that if you only have 64bit vista dvd, you will only have the 64bit version of bootsect,exe so if a 32bit system is installed, you need to get the 32bit to be able to follow this guide.

And what about the scenario where I have only one partition (C:)?

Where should I install the XP.

Ummm... then you create a new partition.

I'm sure if you search, you will be able to find how to do that. Vista can create a partition using disk management console. Need administrator privileges.

Do you mean the Microsoft management console (mmc.exe) or some other program?

Right-click "Computer" --> click on Manage. This is for XP. I can't remember if Vista is the same or they changed it; but it's "Computer Management", then go to disk management.

You may want to test Vista first if it will work for you or you may simply just want to keep your XP system around. In this case, you may go for a dual-boot installation. For dual booting, you need at least two partitions, one for XP and the other for Vista. Both partitions can only accommodate one system. If you only have one partition, you need a partitioning tool to help you out.

A dual boot installation will let you choose between your two operating systems every time you open your computer..

Everyone has different opinions about which version of Windows one prefers... Diversity of opinions is welcome, and, as such, we have set up different sections in the forum where people can discuss their favorite one... :whistle:

In fact, there's even a poll about Vista vs. XP. Would you like to participate?
