I installed Ubuntu 13.10 Saucy unto a USB stick using Pen Drive Linux's USB installer. It won't boot. Booting to a USB isn't in the BIOS boot order. My desktop computer is essentially a brand new i7-3770. Why won't it boot from USB?
Thanks.
Mark.

3If it is brand new you might need to disable secure boot. – Panther Sep 18 '13 at 20:24

not entirely correct - usb-stick needs a boot-flag too !
You can create boot-flag with gparted. plug-in usb-stick and open gparted.
Then look for the drive there, which contains your usb-stick.
Select your usb-stick with one click.
In Menue goto 'partition' - and there 'edit mark' ---> set boot.
So the usb-stick has flag as 'boot' and can be recognized by BIOS.

The boot flag does make a difference! I loaded Ubuntu 16.04.3 64-bit onto a USB drive and tried booting onto it via an old Acer Aspire 5000 laptop, but it would not work! Even when I went into the Bios (using F2 during boot) and set the boot order to be my USB drive FIRST (EVEN BEFORE THE HARD DRIVE) it still would not work...until I set the
boot-flagas you mention above in your answer, via Gparted. Thanks! Now it works. – Gabriel Staples Aug 27 '17 at 21:51

Some machines require you to set a supervisor password in the BIOS/UEFI settings before making available other boot options. If you really dont have a choice which boots the USB, try setting the supervisor password, and see if more choices, including a USB choice, are offered.

you should be wrong about USB-drive isn't listed in the boot order. Maybe you can choose a boot device not by changing the boot order in BIOS but by changing boot device temporarily (F9, F11, ... depends on hardware). If all this fails you'll have to install a grub (or any other compatible Boot Loader onto a bootable hard drive, which recognizes your USB-Stick as a bootable media and will create an entry for the Ubuntu on the USB.

Maybe the USB boot is under the harddisk; so connect the USB before entering BIOS, then check if there is a harddisk boot priority. If so the USB name and model will be listed.

If your on windows check out LinuxLiveUSB maker! Its easy to use, and compadible with almost every popular distro out there :D
Oh and also if you are having issues booting natively to USB you can try to burn a copy of PLOOP boat loader and try it like that. I do that when I work with machines with either the BIOS locked or incompatible boot from USB arises.
