The problem is that I need to boot from a Live USB, but the motherboard does not recognize the USB, and the methods to enter BIOS set up (pressing F2 or DEL) do not work at all. So I guess the BIOS should have been corrupted. On the other hand, the BIOS is written for Windows. So I really feel being trapped and appreciate any help.

You can try to reset you BIOS using the jumper on the motherboard, its jumper marked CRLCMOS1 in the PCB.

Flip it 1 position wait 10 seconds and set it back to the previous position.

After that the update method should work, if not you should assume that your motherboard is really defect.

Thanks. I followed the instructions but still got blank page on the monitor. Assuming my MB is defected, what can I do now? I mean, are there "Ubuntu-friendly" MBs out there? – corev Oct 22 '11 at 19:48
All of them are (mostly), your is just not because you cant enter your BIOS, if you needed to boot windows from a usb you would still be stuck. Really dont see it as a linux / windows problem. If you can configure it you can run it, if your stuck with a problem thats another issue :( – Bruno Pereira Oct 22 '11 at 20:22
btw F10 and F12 normally allow you to choose which device to use for booting, try pressing them during post (press a lot of times every 1 sec, sometimes takes a bit for the option to set in). If you find anything else drop a comment. gl – Bruno Pereira Oct 22 '11 at 20:23
try also F11, its reported to be the correct button. – Bruno Pereira Oct 24 '11 at 22:04

Run a copy of plop boot manager off a cd and then select the connected usb stick with the bios update within plop. It should then boot off the usb stick. Plop is a great work around for motherboards that don't support usb device booting.

I have a Asrock H67M MB on my desktop. To get in to select bootdevice I have to press F11 during startup. Hope this helps.

There is a software called flashrom in the repository that can be used to flash many motherboards and other devices.

If DOS is required in order to run any vendor-supplied flash utilities, then there is FreeDOS.
