I bought a new PC and im trying to install windows 10 and I created a windows 10 boot tool with a USB on my brothers computer (also running windows 10), but the USB is not showing up in the UEFI for me to boot from I can't figure out why this is happening.

Is the stick formatted with FAT32?
Can you start the USB stick with your brothers PC?

With your board:
Go into the bios and load defaults, save and restart into bios.
Go to the boot menu and disable CSM, save and restart into bios.
Can you select your USB stick now in the boot options?

If not, try another USB port.

I have tried both of all of that and it just doesn't recognize my USB no matter what I do.
