    Okay, I have simple question :)
    When I'm clicking F8 to watch available devices to start for I got something like this:

    AHCI - hard drive
    AHCI - DVD drive
    UEFI - DVD drive

    What is the difference between AHCI and UEFI DVD drive? I heard somewhere that this is related to GPT disk formatting instead of MBR, but which one is better?
    I have 1 TB hard drive.

    where everyone wants to be
    UEFI is a new standard of bios design, so that would probably be what the BIOS has listed as the first boot option, where ACHI is a mode that SATA controllers run, and that is probably listing drives by order of first to last by port order. Not sure why it would list that way (if my guess is right as to how/why it is listing the drives).
