    So I tried to boot from USB

    I saw a tutorial to boot from USB, and installed the code on the USB. The issue is with the next step. I changed the UEFI settings and turned off secure boot, turned on boot from legacy ROM, and then turned on legacy boot mode. I got into a Linux console saying that I was missing grub.exe, so I looked up how to fix it. It suggested going back into windows. So I took out the USB stick and rebooted. It booted to a screen that says this:

    Your hard drive with Windows on it is set up for UEFI booting. You are now trying to boot it in Legacy mode. Switch back to UEFI mode to boot from the hard drive.

    As stated, just reverse what you did in the Bios to boot normally.
    What "Code" did you install to a USB? is it from an ISO Image to install an OS, like Linux? Did you burn the USB Flash correctly? Have you tried booting the USB from another computer?
    Though some people on here don't like it, you can create a UEFI Bootable USB Flash drive with Rufus, in my signature, if you have an ISO image of a installer you want to use, so you won't have to make changes to the Bios.
