Pen drive does not boot

[soumo27]

I mounted an ISO of Ubuntu 11.04 on my pen drive via:-
Universal USB Installer. But during startup, I am getting no option to boot from the USB.
What can be the problem?

I have selected the "boot from removable devices" in the BIOS' Boot devices priority as the 3rd option...

Man change the default HDD to the USB drive. Then set the HDD to boot first. Its a prob in ASUS MoBos. Hope that helps

I have a similar mobo M2n68-am se2 and get a similar problem - changing boot option to usb doesn't work.
Thankfully there is a simple workaround, when you see the bios, press F8 OR F12 . You should see the boot option menu. Choose your pen drive from that list and it should boot .
