I just installed Mandrake 8.0 on my old computer. The first time I booted it up it ran and i was happy. However, I had to turn it off to move it into a different room. When i tried to boot it up again, it didn't. It had the message loading Linux for over 24 hours. So I decided to take the hard drive out and try it in my other computer and it worked. When I put it back into the computer I want Linux to be on, it never booted and is still sitting there now. Why won't it boot and what can i do to make it boot?
