    Error 0xc0000225 loop, can't access BIOS, can't find bootable USB


    I'm getting an 0xc0000225 error on my Lenovo laptop. CMD tells me I have 0 identified windows installations. I have burnt a windows 10 ISO onto a USB, but when I go to use a device in Windows Recovery environment I can't see the USB as listed there. I can't access BIOS to boot from USB as my laptop boots too quickly, and when I go to change UEFI Firmware Settings through restarting, nothing happens, it just takes me back to the same error message.

    Don't know what to do at this point, any help would be much appreciated! :|

    How did you create the USB flash drive. The safest way is as follows, and will work on UEFI/MPR/GPT and BIOS/MBR systems.

    Here are the steps to create a standard Windows 10 USB flash drive. 
    This was posted by @NavyLCDR previously and I saved it, tested it and it works:
    1. Use the Media Creation Tool to download and save the ISO file to your hard drive.
    2. Insert the USB flash drive.
    3. Open a Administrator Command Prompt and enter: diskpart (if it isn't an administrator command prompt, it will ask for administrator permission).
    4. list disk
    5. select disk # <- replace # with the actual disk number of the USB flash drive
    6. clean <- this will erase the disk selected above, make sure you selected the USB flash drive!
    7. create part pri
    8. format fs=fat32 quick
    9. active
    10. exit
    11. exit - and if the first Command Prompt was not an Administrator Command Prompt, exit that one too.
    11.  Mount the ISO file saved by the Media Creation Tool. If you are using  Windows 8 or 10, you only have to right click on it and click on mount.  If you are using Windows 7, then you must use a program like WinCDEmu to mount the ISO file:
    WinCDEmu - the easiest way to mount an ISO. And more...
    12. Copy all the files and folders from the mounted ISO file to the USB flash drive.
    That's  as simple as it gets. Between steps 7 and 8 you can enter: "select part  1" without quotes - but it should not be necessary.
    Between steps 8 and 9 you can enter: "assign" without quotes - but it should not be necessary.
