I have this 8 gb toshiba flash drive and my motherboard also allows booting from removable devices. But I don't know, I've already tried to make the flash drive bootable and set in the bios to boot from USB. But it doesn't work. Are flash drives always bootable?

Well, I can't give you any technical explanation, but I do know that I have a couple of flash drives that are bootable and working, and others that don't (using the same techniques). So I guess the answer is:

No, they aren't always bootable.

Not sure if there is any way of knowing if a flash drive is bootable other than trying it though.

i'd guess that your issues probably stem from your BIOS (or your motherboard USB chipset) rather than the drives themselves, but it's possible the drives' chipset/firmware is missing a feature or two. if a flash drive isn't boot-capable, those are the only areas to blame. – quack quixote Mar 14 '10 at 2:53

You need to make the flash drive bootable. Google bootable flash drive.

Also don't call the Flash drive "FD" people will confuse that with Floppy Drive...

its already bootable, I always use linux live usb creator. But it seems that the motherboard is the problem. – Ieyasu Sawada Mar 14 '10 at 0:29
What you need to do is make sure that your BIOS is checking your USB drives FIRST as it's POSTing. If it is still not working and you know booting from your USB is first find your MoBo support site and see if there is a BIOS update. Also old Mobo's tend to not support booting from a flash drive. How old is your Mobo? – anon31097 Mar 14 '10 at 0:34

Go to the manufactures website and see if they have a BIOS update for you. – anon31097 Mar 14 '10 at 22:52
