I want to install Ubuntu 12.04 on my netbook. I created the bootable drive on a laptop using unetbootin and also with two other tools. However in every case when i plug it in my laptop, and boot from it it says "error: prefix is not set" and then garbage comes on the screen.

My netbook came with freedos, so i have to install this. Help

Post the options you get in your bios boot menu.Is it UEFI capable???
