System error

[dragunov]

The only couple of things that I know of which bring about the "Disk Boot Failure" error are:

1. The VBR can't find or load the system files or there was a problem loading them.
   
2. During the boot process, the BIOS checks the last two bytes in the MBR (first sector of the drive) for a signature value of 55AAh. If the last two bytes are not 55AAh, an Interrupt 18h is invoked, which calls the subroutine that displays something along the lines of "Disk Boot Failure..." etc. So, ultimately this would suggest that your MBR is corrupt or non-existent.
   
3. Your HDD has not yet been partitioned.

Do you have your operating system CD? Complete the guide here, or run a repair installation and your PC should be good to go.
