I suspect that you could not format because the version of dos on your floppy was older than the version current at the time 2000 was loaded. You probably need a newer boot disk. You might try doing an FDISK and deleting the partitions then putting them back and then format. The symptoms you observe are consistent with a hard drive problem, in my experience, but you never know.

When you turn the power on there are several minutes of black screen and the hum of the hard drive. Next after that long delay there is a very quick flash on the screen with a large Intel logo that reveals "Intel work station board" along the bottom. After another long wait, Windows 2000 starts to boot up but before completion the screen turns blue with the message: "STOP: Inaccessable_Boot_Device". With a floppy I was able to run a virus check and I ran chkdsk /f which found nothing. By hitting the F8 key during the boot-up you are able to choose several boot-up options. I tried them all with no success. Because there is nothing of importance on the hard drive I put in a DOS floppy and typed in the FORMAT C: command. Don't remember exactly what that message said here but I believe it was something about not having the right version of DOS. Don't know anything about the computer other then it is running Win 2000. No brand name on the Box. I would appreciate any suggestions as to getting this thing up and running again.
