I have switched several times between different Ubuntu and Windows versions in the past several years, and decided to go for Ubuntu again. After downloading a 64-bit 13.10 Ubuntu Desktop, I tried putting it on my 8 GB flash drive (which I've used countless times for this) but whenever I try to boot from it I get a BIO Flasher Utility instead of Ubuntu. I tried both FAT32 and NTFS as well as using both Unetbootin and Universal USB Installer, all with same results.

If it matters, my motherboard is Biostar G41D3 and my CPU is Intel C2D E7500.

Although I got no idea why it happens like this, when I changed the boot priorities in BIOS (I was using the quick boot menu all the time), it just worked without problems. – A. Andevski Nov 27 '13 at 0:01

For the flash drive to be bootable, some applications (if not all) require it to be in FAT32 (like Unetbootin).

¿Did you try the Startup Disk Creator? (you need an Ubuntu for this).

Here are some other methods you can try:

If you are in Windows, you can try LinuxLive USB Creator (

Try creating the USB using Unetbootin as stated by Johny, and change the BIOS setting of Quick Boot to Disable.
