Backed up XP on version 11. Now have windows 7, wish to go back to XP.

Hi Everyone,

This is difficult to explain, I'll do my best.

I have had two HDs in my computer, one approx. 80 gig, and the other 1 tera, respectively.
I replaced the 80 gig with the 1 tera, so both not in the computer at the same time.

Both have had XP on both of them. I backed up both HDs on an external 80 gig HD,
using version 11, build 8,053.

I had windows 7 installed only on the 1 tera HD, which is in my computer right now.

I wish to go back to XP in the 1 tera (I know no updates.) I do not have windows.old
in windows 7.

Do I need to format the 1 tera HD, or simply reboot, and use restore and the external HD
with version 11?

Does it make any difference which back up I use off the external backup HD?

Cheers and thanks for help.

Steve
