If you have a boot disk which contains FDISK and FORMAT. Simply boot using it. Use FDISK to remove all the partitions, then reboot. Reformat the partition using DOS FORMAT, then use the command FDISK /MBR to recreate your MASTER BOOT RECORD using the standard MS-DOS MBR. This will allow the drive to boot. If you use FORMAT /S then you can boot off the drive as well. Installing Windoze is a infinately more complex issue though. Jolyon
