I inherited a used hp/compaq dc7600 desktop after we upgraded at work. The hard disk was re-formatted but it came with a set of HP XP and Restore disks - unfortunately for a dc5800. I optimistically ran the automated format and install of XP. It seemed to work, then asked me to reboot.
On reboot it returned to CD, so I messed with the bios so it reboots from HD. Now it refuses to boot from hard disk.
Do I need correct disks to get this working? Am I missing a step or trick?
