Can XP 32 be run with 64-bit W7/hardware - without mods? If mods are required, what might that entail? I understand that W7 will run virtual XP, but that's not what I have in mind.

Hi,you would like to have TWO Windows installations on same machine? 99,9% hardware, which is supported on Windows 7 is also supported on Windows XP > here is no problem. You can run/install XP on new hardware.

Hi, You would like to have TWO Windows installations on same machine? 99,9% hardware, which is supported on Windows 7 is also supported on Windows XP There is no problem. You can run/install XP on new hardware. Actually, it's two drives, same 64-bit PC. One drive has an existing XP system, the other will be loaded with W7 (64). If I understand you correctly, there should be no problem running XP (32). Thanks for the feedback

Hi,yes, you understand correctly.If you had Windows 7 installed after XP, then you have in bootmenu Windows 7 and Windows XP.
