Windows 7 WinXP & WIN7 on same Partition - no Multi boot possible - HELP!!!

[Wargazm]

Hi All!
I think I have made a rather "NOOOOOOOOOOOOOB" mistake and installed Win7 on the same Partition as WinXP. I was in a hurry and forgot totally to partition the HD before I installed, was doing 100 things on the side during the Installation, and noticed my mistake only AFTER the install was complete.... my question....
Is there any way I can do a Multi boot for those two OS now? The WinXP folder has been renamed to Windows.old, and even with EasyBCD there´s no way I can get the Comp to boot into WinXP.
Any help in this matter would be greatly appreciated!

All I can suggest you check is the following reference. Go through the entire thing to see if some parts are more applicable.

You might even think of re-installing XP and moving your files to that install. But installing XP after Windows 7 can present some problems.

You have two main options:

1. Install xp on a newly created partition. This will require some subsequent manipulation of boot settings using something like easybcd but is not terribly difficult. You could then remove all the .old stuff relating to xp in the .old folder.

2. You can recover the xp installation from the .old folder then install Win 7 to a new partition - see this MS document:
