I just bought a new Asus X501C laptop and was annoyed by the fact that there was no USB drive boot option available in Bios. I could not even find a way to rearrange boot order because it doesn’t even list the flash drive I have.  Here is a workaround I found. Asus no usb boot option.

  • USB device is plugged in
  • F2 to BIOS
  • Switch to “Boot” and set “FastBoot” to Disabled
  • Switch to “Security” and set “Secure Boot Control” to Disabled
  • F10 to save and exit and immediately press F2 to BIOS
  • Only then could I switch to “Boot” and set “Launch CSM” to Enabled
  • F10 to save and exit and immediately press F2 to BIOS
  • Now select a boot option. My USB option didn’t say USB, it was just [ 8.0.7]
  • F10 to save and exit – booted right to USB
