So here's my situation I have a desktop (IDE/PATA) running Umbutu 12 and our laptop (SATA) craped out but the OS is fine (it the CPU that died.) So I slapped it into a usb case and plugged it into desktop.
with the IDE unplugged it boots to Windows so I know that works. but with the IDE in it boots to Umbutu i have modified the bootloader so there is a choice to boot into one or the other. But when I boot windows I'm getting a loop of "windows is loading files..." then reboots. I know when in the laptop i can get to the user screen but not in the desktop.
I've migrated the drive between laptops before but it doesnt work this way
