actually Windows Server 2008 R2 trial software (for 180 day evaluation)?
Chances are that you burned the ISO to the DVD as a file rather than burning the ISO image to the DVD to create a bootable DVD.
If you have a computer that is running OK and you insert the DVD and browse its contents what do you see?
I'm trying to install Windows Server 2008 on 2 Compaq ProLiant DL580 G2 servers. Problem is, neither will not boot from the dvd drive, nor external dvd drive. The boot log, says attempting to boot from dvd, then onto floppy, and then boots from hard drive.
ProLiant DL580 G2
8GB ECC RDIMM DDR2
2x 1.4Ghz Xeon MP installed
3x SCSI (9GB+9GB+36GB in simplex mode)
