OSD: Boot from USB

I wanted to boot the OS from offline media (USB) for a HP laptop. I have changed the BIOS setting which enable boot from USB.

However, the laptop dint boot from the USB drive after I restart the HP laptop.... >.<
After few attempts, I pressed F9, it prompted me the "Boot sequence". I choose USB as my 1st option and then restart again.

Finally, my OSD boot from USB!

Happy trying!

Tips for Boot sequence setting:
IBM - F2/F1
HP - F9
Dell - F12
