When dealing with a Blue Screen of Death at boot - the first option should be to boot into Safe Mode (press F8 during bootup). From safe mode you can run a system restore with %systemroot%\system32\restore\rstrui.exe
Some hardware failures are so severe they prevent booting into Safe Mode.
The recovery console allows an alternative boot option giving a limited command prompt - this can be used to disable services or replace system files until you are able to boot into safe mode.
Recovery Console commands: ATTRIB Change file attributes BATCH Execute a batch file CD Change directory CHKDSK Check Disk CLS Clear screen COPY Copy files* DEL Delete Files* DIR Directory listing DISABLE Disable Service DISKPART Create or delete disk Partitions (like running setup) ENABLE Enable Service EXIT Quit the recovery console and reboot EXPAND FIXBOOT Write a new boot sector to the system partition FIXMBR Repair the Master boot Record FORMAT FORMAT drive /FS:NTFS HELP LISTSVC List all services and drivers LOGON Logon as administrator (local) MAP List local physical drive mappings MAP arc List local physical drive mappings(ARC path) MD Make Directory* MORE RD Remove Directory* REN Rename file* SYSTEMROOT Set the current directory to be %Systemroot% * File operations are only possible on: system directories, floppy drive(removable media), Root directories, local install sources. You can copy FROM but not TO a floppy disk.
The recovery console is not installed by default, from the install CD use the command: D:\i386\winnt32 /cmdcons
Then restart the machine.
