If I prepare an ubuntu startup usb with unetbootin or startup disk creator, it does not boot on my pc. But if I format the same drive on Windows, then restart on linux to create the bootable usb, it works.

(Yes, I must format the usb drive on Windows 7 first for linux to boot).

I have Gigabyte GA-880M-USB3 mainboard.

My guess would be that you need to set the boot flag on the flash drive. You can do that with gparted or fdisk. – bodhi.zazen Feb 4 '12 at 5:23

My experiance is that both UNetbootin and usb-creator like FAT32. Some flash drives come formatted FAT16. I have had good luck formatting Live drives using gparted from the Live CD.

I format my USB drive with palimpsest. When palimpsest is about to format a partition, the option FAT means FAT16? If so, that explains it all and my question i'll format my usb a few hours from now just to find out. – th3pr0ph3t Feb 5 '12 at 15:49
Thanks! I'll try gparted next time. I hate to see Windows as the solution. – th3pr0ph3t Feb 21 '12 at 20:28
