I updated the BIOS to the latest version using WinFlash utility provided by Asus on my UX31A Touch notebook. I went from BIOS v218 to v219. The WinFlash utility stated my upgrade was successful and proceeded to ask me to reboot... which I did.
After reboot, the notebook immediately went into the BIOS config screen. I immediately tried to 'Quit and Exit'... and the notebook rebooted... and it went back to the BIOS screen. I tried doing 'Save Configuration and Exit'... same thing... rebooted into BIOS screen. No matter what I did... it wont go pass the BIOS screen.
oh crap...
Played around with the BIOS settings to try and figure out what was going on... To cut the long story short, I did the following...
- In Boot Menu --> Change FastStart to [Disable]
- In Security Menu --> Change Secure Boot to [Disable]
- .. then 'Save Configuration & Exit'
- When the BIOS screen appears again, go to the Boot Menu again --> Change Launch CSM to [Enable]
PHEW!!!!.....
