I would expect (attempting to) boot a foreign drive put into a different, diverse system to be a hit or miss experience.

(Actually, in most cases, I'd expect Windows to automatically find, install, & "fix" incompatible drivers & such - at least to the point where it would boot, successfully. But maybe the architectures are just too diverse here?)


Anyhow, is there a particular need to boot from the old drive.
The drive is there, a slave, drive D: or E: or whatever, can't you simply copy from D: to C:...
