How To: Fix Windows Boot Failure

Applies to: all versions of Windows

Symptoms

When you start your computer, one of the following things happens:

The system halts displaying a black screen with no text.
The system halts displaying the message: "Boot failure. System halted."

Cause

This error may occur because the computer is trying to boot from a disk that is not bootable, or because the boot files on the disk are corrupted.

Solution

Check the boot drives

Check that there are no removable drives connected to the computer which it might be trying to boot from, including floppy disks and CDs / DVDs.
Go into the BIOS Setup utility and check that the hard disk settings are correct and that the first drive in the boot order is the hard disk.

If this does not resolve the issue then you will need to try repairing the hard disk boot sector. If you are using Windows 95/98/Me and have made a recovery disk then you can use this. If you have original Windows 2000 or Windows XP installation media then you can boot from this and use the Recovery Console to perform a repair from the command line.

If you don't have a bootable repair disk then the easiest way to fix this problem is to use Spotmau PowerSuite.
