How to access BIOS on an ASUS laptop?

I just bought an ASUS laptop with Windows 8 installed. How can I access the BIOS?

I tried to click any of the usual keys during power-up: ESC, DEL, F10, F8, F2... non of them work - I just get to Windows.

How can I determine the correct key? Do I have to just restart my laptop over and over again, trying each of the keys on my keyboard, until the BIOS shows up?

Solution 1:

I was able to find the following instructions. Having done this myself in the past I can confirm it works.

On systems with Windows 8 pre-installed, you can access the UEFI (BIOS) setup screens from the Windows 8 boot menu:

1. Press the Windows key + C, or swipe in from the right edge of the screen to open your Charms.
2. Click Settings.
3. Click Change PC Settings.
4. In PC Settings, select General.
5. Under Advanced startup, click Restart now. The system will restart and show the Windows 8 boot menu.
6. In the boot menu, select Troubleshoot.
7. In the Troubleshoot menu, select Advanced options.
8. In the Advanced options menu, select UEFI Firmware Settings.
9. Click Restart to restart the system and enter UEFI (BIOS).

PLEASE NOTE:

These instructions only apply to Windows 8.0

Solution 2:

Press Windows Key+C to open the charms menu, click the gear, click power, and then hold shift and click restart. When the windows advanced startup menu opens, click troubleshooting, then UEFI Firmware, then click restart
