    Boot failure windows\sys32\osloader.efi Want to fix boot issue.


    I have a windows 10 desktop with 3 drives
    An SSD (C)
    1TB (E/F
    74GB (G)

    All working well, until motherboard failure. Had motherboard replaced. Ever since , it does not boot correctly.
    No hardware other than the motherboard was replaced.

    When the boot error appears I cam hit the Windows 10 option and boot into the OS.
    Another issue is that now the D drive (system) fills up and the D:E:F: drive (on the 1TB) regularly runs at 100% for simple file retrievals. I have tried looking at the config. Tried a repair several times but no success.

    Any and all suggestions will be most welcome. (Used to be a techie many moons ago, but completely rusty now)

    If possible, please run the BETA Log Collector.

    From what I can tell, it seems that your system somehow is quite messed up in a few areas.
    The System Reserved partition is a partition you should not see, it contains very important files that you should not touch.

    osloader.efi boot failure issue


    Thanks for the response. I have a feeling it is to with the EUFI settings because the old motherboard used its BIOS for the settings. I am not too familiar with EUFI settings.
    Also before the board change the secondary drives never ran above 20/30% disk utilisation, but now they (DEF only) is at 100% almost constantly. Attachment 226752
