There might be a BootDisk directory or something on that CD. Since you can't change your BIOS settings, try making your CD-ROM Master and your Main OS Drive Slave and see if it boots off of the CD. If it does, then use the recovery console (I think you press R or something at the Setup Screen) and run the "chkdsk /r" and the "fixmbr" (sans quotes) from the recovery console. If you get it to come up successfully, you can install the Recovery console as a boot option (installs it to drive and puts an option in your boot.ini file) by running "d:\I386\winnt32.exe /cmdcons" (d: is the drive letter of your CD-ROM).
