    HDD not recognized GPT UEFI


    Hello,
    I've got an Asrock Fatal1tyZ68 Professional Gen3 Mainboard. Before I had Windows 8.1 installed on a small 512GB HDD with MBR and everything worked fine. Now I've switched to a 6TB HDD. The Problem is I had to switch to GPT because of the size.

    The strange thing now is. When I unplug and replug the HDD it is recognized as a bootable UEFI option. When I restart it is not recognized as an UEFI option anymore. When I try to boot the HDD without the UEFI option I only get "please select a bootable device".

    The workaround can't be that I have to unplug the HDD everytime I need to restart!?

    What can I do?

    if you can disable legacy support via the bios...
    set drive controller as AHCI

    see if that helps

    No there is no way to do that.

    Drives already set to AHCI.
