  8. Troubleshooting theWindows NT/2K/XP Boot Process • To recover from a failed boot: • If Windows startup menu appears, use Last Known Good configuration • If unable to boot from hard drive, use three boot disks that came with OS and select the option to repair a damaged installation • Try reinstalling Windows NT into same folder it currently uses; tell Setup it is an upgrade • Move hard drive to another system and install as secondary drive (last resort if using NTFS)

  9. Last Known Configuration • A copy of hardware configuration from the registry that is saved by the OS each time it boots and the first logon is made with no errors • Contained in the registry key: HKEY_LOCAL_MACHINE\HARDWARE • Reverting to it causes loss of any changes made to hardware configuration since Last Known Good was saved
