I have a Dell XPS machine (express code=cndrz81) where the hard disk died and I had to install a new one. I need to reload the OS, but it will not boot from the floppy or the cd-roms. All three have power and spin up. I get a message the "no boot device available". The BIOS setup shows that these devices are NOT installed (although they are).
Any troubleshooting thoughts would be appreciated.
