    UEFI Boot


    Following a Windows 10 updateto version 2004 on 18thAugust 2020, my PC goes into a boot loop, I can get out of it by pressing F12 and selecting Windows Boot Manager rather than the default UEFI partition 1 on a Kingston SSD. The PC then boots and runs normally.
    I would like to repair/restore the UEFI partition - I have tried the startup repair using ALT-F10 but this is unable to fix it. I have also looked at the SSD and partition 1 shows as healthy.
    Any help would be much appreciated.
    PC is Acer Aspire XC-885.

    :)

    AsRock Z77 Pro3 - AHCI? UEFI?

    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).

    UEFI Boot

    Can't disable UEFI boot on HP 250 G3

    I got it, I was not accustomed to UEFI (because on HP 4540s I disabled it) and I automatically thought that if I boot from the first menu it will boot in UEFI mode, but I have to go to second menu "Boot From EFI File" to get a list of EFI boot options:

    I installed Ubuntu Mate and Windows 8.1 from the first menu (the picture) and they both installed in BIOS mode. Quite simple really.
