how can you be a techie if you dont know something simple as this?
get a windows disk and try booting off it - if it works from bios its windows, if it doesnt its the drive/setup/config
you should also have a million spare hdd's to temp. install windows to and see if its your install
you should also have a million space dvd/cd drives to try instead
im a techie, you calling yourself a techie, im nothing like you.
All the suggestions you have offered have been done........the drive works in Windows XP but not in windows 7 and it has been tried with other Windows 7 installs..........Nice try but they have been done.
