Hi Now this should be simple to do but for some reason my PC just won't boot from a DVD (Windows7). I have a GIGABYTE GA-Z77=DS3H and I have changed the SATA mode to AHCI, and when I restart the PC I go into the boot sequence (F12), where I select my DVD drive but it just keeps booting from the C drive. What am O doing wrong? It only has 1 SATA LG DVD drive Any Suggestions
