OK, so I've got a Stinkpad T61 that originally shipped with Vista, and I need to "downgrade" it to XP. Unfortunately, booting off the XP CD gives me a "no hard drive in machine" type of error, and reboots.
I used Linux's disk utility to wipe the Vista partition, but no dice. I wiped the recovery partition, and still no dice. I can install Linux on the machine, boot it, everything works fine. STILL no dice. The damn XP installer refuses to recognize the hard drive.
I have no clue what to do at this point, other than chuck it through a window.
Tried installing something older? 98se?
