When the Boot Process Fails
NTLDR could be missing or be corrupt: Use the NT Emergency Disk and select the “Verify Windows NT system file” option.
Other NT System files could be missing or could be corrupt: Use the NT Emergency Disk and select the “Verify Windows NT system file” option.
If all else fails, re-install Windows NT Server, but do NOT allow the Installation program to re-format your hard disk, if you do, you lose all your data.
