Had a windows xp pro 32bit pc that wouldn't boot. Installed windows 7 ultimate 64 bit and now every reboot halts on can't find c:\windows\system32\hal.dll. If I leave the install dvd in the drive everything is fine. Any ideas?
If you can boot into Windows 7 get the latest version of EasyBCD here.
Add a new XP entry, and let it autoconfigure when prompted. You should now have a dual boot, if thats what you wanted that is. Or did you just install Windows 7 to try to get XP working again?
