I purchased a new hard drive and put it on SATA 0 (unformatted). At the same time I replaced two internal CD/DVD devices from my one IDE ribbon with one new HP DVD burner (set to master). Threw out floppy and associated ribbon (FDD). The goal is to boot from DVD and install OS. But if I activate AHCI in BIOS, the BIOS finds the hard drive but loses the DVD and I get ugly message BOOT DISK FAILURE. If I enable IDE mode (disable AHCI) everything works fine. How can I take advantage of AHCI and keep my DVD burner?
