Windows 7: Error after installing Win XP on partition

Yes you will need the bcdedit lines if you have installed XP after Windows 7. If you installed 7 after XP it would be a different story.
Hi -

Okay I reformatted and reinstalled XP once more, and am now following the steps.

I did the bootsect command with no problem, then moved onto the ones you gave.

after typing the first command you gave the bcdedit /create one I got this error: 'An error occurred while attempting the specified create operation. The specificied entry already exists. Cannot create a file when that file already exists.'

I did the next 3 anyway and they were all successful.

Rebooted, but it went straight to XP.

Any further ideas..?

Edit: I installed EasyBCD again and it ran fine, and followed the instructions but both Windows XP and Windows 7 already appeared on the entries list, and I didn't need to add a new one (although Windows 7 was under recovered?). I still reinstalled the bootloader, restarted, but no boot options again.

That's what happens when you use the automated recovery tools on the DVD.

If you would like me to help you over Teamviewer, I can.

For some reason the file bootmgr is missing from the C: drive. I cannot run the command-line tools from within XP because the programs are 64-bit Windows 7. So you will need to use the Windows DVD to do some more repair.

Consider using the tools bcdboot and bootrec

It seems the BCD somehow got hosed. Probably the automated recovery messed it up.

I reproduced that behavior by deleting the \boot folder and bootmgr file on my computer. When this file is missing, the system automatically boots into Windows XP (even when the Windows 7 boot sector is installed).

To repair it, I booted from the Win 7 DVD and did:

bcdboot c:\windows /s c:

bootrec /rebuildbcd

Now all is left is to recreate the BCD entries for XP, which we've already discussed previously.

bcdedit /create {ntldr}
bcdedit /set {ntldr} description "Windows XP"
bcdedit /set {ntldr} device partition=c:
bcdedit /set {ntldr} path \ntldr
bcdedit /displayorder {ntldr} /addlast

Yes , Vista /7 bootsector code is capable of handing control to ntldr.

Is ntldr on The 7 Boot partition - or is it on the System Reserved partition?

ntldr and boot.ini are on the Windows 7 partition, C:, which is why I have accounted for that in the commands. I took a quick glance at Disk Management and I don't remember seeing a system reserved partition.

Only bootmgr was missing from C: (\boot\bcd was there) and I think that is the source of the problem. The bcdboot command will put back the bootmgr file. And the BCD was hosed, so that needs rebuilding as well.

Apparently he had changed some things around, because I remember seeing a couple of black chunks at the beginning and end of disk which means that space was unallocated.

Another thing he did is convert XP to a primary partition, which is something I recommended earlier because I thought it was necessary at the time. It turns out it wasn't. If the boot files are all on the Windows 7 partition (and working properly), XP can indeed be booted from a logical partition.
