Booting from USB / option not available

adamdynamic

Hey,

I've been going round and round with circles with this for an hour, I'm hoping someone here can help me?

I've managed to install Ubuntu onto a USB stick, when I boot up my computer and hit f12, sometimes my laptop (Dell Studio 1737) gives me an option to boot from a USB device, sometimes the option doesn't appear. When I go into setup the USB always appear in the 'boot section', moving it up to the top of the list doesn't seem to have an effect, nor does restoring boot settings.

Am I missing something obvious? Is there a reason why I can do it sometimes and not others?

Any help on this would be much appreciated!

Thanks,

Adam.

It's possible that it's a bug in the BIOS.

Some USB chipsets can take quite a while to "settle" and be registered correctly after power-on/reboot, and if the BIOS is not programmed to wait long enough, it may not always detect that a USB bootable device is available.

Have you checked to see if any BIOS updates are available for that model?
