    Uefi to legacy mistake :(


    My system: acer v5 471p-6843
    windows 8 64 bit
    So basically I was messing with my bios settings and I changed it to uefi to legacy and when I restart it it says no operating system with that pxe
    When I try to boot into bios via f2, f12 , esc , del all of them don't work. Now I'm stuck unable to boot into bios. I made a recovery USB for win 8 but it doesn't give me a boot into firmware option. So I have no idea how to get back into bios to set it to uefi again

    I'm able to boot anything with USB and DVD but I can't install windows on a seperate partition, but I don't think you're understand my problem. My problem is I can't access bios to change legacy back to uefi. F2 don't work recovery doesn't work

    Can you post a screenshot of Windows Recovery ?

    If I can gather enough info, I may come up with a solution.
