"Reboot and select proper boot device" error ?
I am just trying to install a clean version of Windows 11 and I keep getting that error. I know my bootable usb stick works because I have used it on other computers plenty of times. I tried disabling and enabling fast boot, CSM, changing boot order and it still gives the following error. Please help.
Apart from what HoldenStorm said, another issue could be secure boot. You mentioned fast boot but not secure boot. Whenever I have problems with usbs, it's usually secure boot.
Sometimes certain USB ports may have issues. Try plugging the USB stick into a different USB port, preferably a USB 2.0 port rather than a USB 3.0 port, as compatibility issues can occur.
