So, it's a very long story of how I got to this point, but, essentially, I am trying to install Windows 10 in UEFI mode from a bootable USB. (I used the Windows Installation Media in Windows 10 to create the USB. I've also tried Rufus and a lot of other things...)
The USB works to install Windows in CSM mode, but if I switch my computer to UEFI boot mode, I get the message of "No bootable drive." Is there a way to fix this or am I stuck in CSM mode?
