Had a hard drive go south on my hp. It has set for about 3 months. I found a used 20 gig hd to replace it but I can not get the floppy to work so I can format it. I was using the xp boot disks and went to restart system and it says operating system not found. Tried the xp boot disk again and it did not detect the floppy. Even went so far as to try the xp start-up disk. Still no go. It has a check mark by it in setup.
