I was going to repair a WinXP install on one of my PCs using the WinXP disc ie booting from it (not under a windows environment) but it seems like the boot process completely ignores it. The disc is fine too, used it to install XP many times without using floppy discs to initiate the install. I did recently change the DVD-ROM drive and the Writer in the PC but haven't changed anything else apart from making sure the DVD-ROM drive is set as a boot device after legacy floppy. I also tried booting from the writer too but it was a no go. The optical hardware is relatively new and the motherboard is a fairly old ASUS A7V333. Are these new optical drives incompatible with the motherboards "boot from cd-rom" feature?
