I managed to get to a screen where i can choose where to boot from, but only my CD/DVD Drive and hard drive are there. I also managed to get a command line that looks like this: "grub> " is that helping?

Hi David, welcome to Askubuntu. To answer your question it would be nice to know would exactly you are doing, what you think your computer should do and maybe what you did so far. The more information you give the more likely it is to get a correct answer. –  qbi Dec 24 '12 at 19:35
Have you already installed Ubuntu (or tried to install it)? Or are you trying to boot from the USB flash drive to first install Ubuntu? Was some other OS already installed? If so, what OS (or OSes)? –  Eliah Kagan Mar 5 '13 at 14:10

USB device can be presented in the list of boot media as a Removable Device, but it can as well be detected as one of your Hard Disks in which case you won't see it on the list (your HDD is going to be the default). In this case (seems to be your case) you need to get into BIOS by pressing F2 or Delete during boot -> Find Boot tab / Boot Device Priority section there -> Select your USB drive as the first hard disk and your primary HDD as the second -> Save and Exit. You should now be able to boot from your USB drive by selecting hard drive option from the list of boot media.

Afterwards, when you remove the USB drive, you should be able to boot from HDD without any other changes, but can make your HDD first bootable hard disk just to make sure.
