boot from disc: loads windows installer = no hard disk found
bought brand new hard drive and external hard drive case (USB)
installed new hard drive and boot from disk = same thing
boot from origional hard drive connected to USB = no hard drive found
installed windows on new hard drive connected through USB - install complete - restarted computer and got same F11 loop
restart pressing F8 = F11 loop
about the 50th try the computer booted normally but it took a LONG time to load windows. after that it ran fine, but I don't remember what I did. I backed up everything that would fit on 2 4gig memory sticks, and installed the software that came with the external hard drive reader.
restarted computer = F11 loop again
Reinstalled new hard drive, started computer, went to boot menu, selected cd drive with windows disk in. When it said press any key to boot from CD, I did nothing, this skips the F11 screen and starts to load windows, but halfway through the load I get the blue screen of death with this code:
*** STOP: 0x0000007b (0xF79DD524, 0xC0000034, 0x00000000, 0x00000000)
Can anyone tell me what the problem is?
