There's no telling what'll work and what won't. I've had software work perfectly on one machine and refuse completely on the next.
I don't think just changing the boot setup in the BIOS will get it to boot the "new" Win 7 clone config. Win 7 doesn't seem to do it that way.
The boot drive under XP is the first partition on the first (IDE) hard drive. That's pretty standard, I guess.
The present boot drive under Win 7 is the 4th partition on the second (IDE) hard drive.
The clone Win 7 is the second partition on the third (SATA) hard drive.
I'll try later telling it to boot from the SATA and see if it can work out where to go.
Off out to a theological meeting now...
