I'm asking you this question for a friend. His problem is that when he started up his computer today, the computer just produced the line "Operating system not found" and then stopped booting. We then tried to start it up with a diskette which worked just fine. But when we took a look at C: it was empty exept for a few files and was the size of a diskette. We then took a look at the partitions using fdisk (since we couldn't access h:), fdisk said that there weren't any partitions on the HD. After this we decided to format the HD and start all over again. We installed Windows 98 without any problems, and my friend then began reinstalling his programs. During this process he restarted the computer several times without any problems. But when he started the installation program for winzip the computer suddenly froze and when he restarted it the problem was back again.
So what could be causing this? Could it be the CIH virus, that was the best we could come up with.
Please help me to help my friend
