You are saying you could reinstall windows, xp I assume with no problem from the cd or by running with F5 (I think) on booting?? And then you say putting a disk in, nothing happen. Is there something I don't get?
And then after the first reboot it stops at he logo witout a '' no device available to boot'' Something fishy. First look in BIOS (F2 or Delete) on booting to see if your HD is detected. Must be if you can reinstall windows. Try F8 for safe mode, but I doubt. Very fishy.
