I've attempted to delete it.. I was unable to with any windows software I new of, so I've used a mandrake disk to delee the partition. unfortunately, when I attempt to install windows, I get the BSOD.. registry error. The onyl options I can think of are a complete "low level" format of the hdd where I lose my data.. or slaving and copying.. both present some problems. I can't explain a registry error from an installation disk, I can't proceed to a point where I can make any changes. Thank you for your help.
