Samsung laptops
BIOS / setupF2
Boot menu (start from USB)F10
How to use it
- Shut the PC down completely (hold Shift while clicking Shut down, so Fast Startup does not skip the key).
- Press the power button.
- Immediately tap F2 about twice a second until the BIOS opens. For the boot menu, tap F10 instead.
- If the boot menu does not appear, turn off Fast BIOS Mode in the BIOS first.
