Cant navigate UEFI menu.. I accidently disabled USB!

    Configuration settings for UEFI are stored on EEPROM (aka NVRAM: non-volatile random access memory) This includes desktops as well

    Most tablets provide no means to physically clear "CMOS" either.


    If you would like, you can try to dump the contents of the BIOS ROM with this tool.
    (Windows Defender will flag this tool, exclude it)

    BIOS Backup


    Modifying settings in a BIOS dump is very involving, and should only be performed by someone who is extremely knowledgeable with the firmware they intend to edit. Improperly changing one byte and flashing will result in a device that will not work.



    Since you can already boot into windows, you can easily install windows from there.

    There are a bunch of ways to accomplish it. I can write a quick guide of the easiest most thorough way for you if you want.

To me, this is a huge oversight on Microsoft's part. Imagine being able to boot up your PC, go to Metro, then fire up Steam big picture mode and play your games without ever needing to touch your mouse and keyboard (except, of course, if you are playing an FPS or RTS :3 ) I don't get why this...
