I wonder if the bios is set to look for the originial hd?
Instead of auto detect its user defined.
Trying to boot from it even set up as a slave leads me to believe it.
What would happen if you disconnect the cd rom and hook up the hd on that ribbon cable? Same thing?
I would go back into the bios and make sure it was set up as auto select.
Have you tried to format the hd in another machine?
As mentioned above #3 "You may not be saving when exiting."
I have only run into 3 machines (all dells) that would allow changes to the bios but the changes never took effect because they were password protected. There was never any mention of the protection. Going back in, it a peered the changes had been made but they hadn't.
The 3 came from the same company. Wish I knew what program or how they managed to do this.
It does sound as though the last owner played with the bios.
Sometime selecting "Default" settings is a good jumping off point to get a fresh start.
May have missed any mention of what type of computer we are talking about. Desktop or laptop.
This sounds like a fun puzzle to resolve.
