Windows XP reinstall fails



Hi I'm running a Dell Dimension 8100 (1.3ghz, 256ram) and i used darik's boot and nuke, guttman ran for 2 days showing 2 different IDE deletions or something. The first one said it was complete, and then the second one was only on pass 27 out of 37. I had a power failure, and when i rebooted, it said "strike F1 key to retry boot, F2 for setup"
I HAVE NO CLUE WHAT TO DO! any help would be great, thanks a lot!
If you use DBAN you have erased your OS and filesystem, so all your data is gone.
Seems to me that you either have two physical disks or two partitions that have been wiped, so you need to reinstall your OS and applications...
