I am running win 2000. I have Mcafee as anti virus. I noticed on my HD I have only *GB avaialble and 12GB Unallocated. I downloaded partition magic and this told me ythe same thing. I followed steps to allocated and the system re/booted. Unfortunately it picks up error and again re/boots and goes into loop. My only way out was to go back.
Any ideas. I think the only solution is to re/format the HD !!
