I have a very old (but working) computer, that had windows 3.1 installed on it. I used a windows 98 startup disk to fdisk the hard drive. That worked fine, but when it restarted, it won't recognize the boot disk so i can format C: and install windows 98. it only shows a black screen, and says "missing operating system". it won't let me get to the BIOS by pressing the delete key, either. How can i deal with this, so i can install windows 98? Thanks.
