Re: Taking an OS off a HDD??
first off, taking an OS to a disk and "installing" it would work based on my knowledge, HOWEVER... there may be a possibility you could create a backup file of you entire system and run it as a restore on the other... i don't know you whole situation (lack of details), so this is all i can say.
