Trying to boot Ubuntu from USB - Only getting FreeDOS command prompt

Question

How do I install Ubuntu from an USB drive / create a live USB-stick?

I own a little Acer Aspire One with no CD drive (it's a 10' notebook and was given it with operating system / AVG failure and wont boot windows). So I thought I'd put Linux on it. I have a CD with i386 - 32bit (as it is compatible with MOST things) which I've had running on a HP notebook of a friend's. I have created an ISO with IMGburn and created a boot-able thumb drive (4 GB Imation) with Rufus.

When I boot from USB, I am asked for a keyboard layout - no worries and then I get a command prompt (FeeDOS DISPLAY version 0.013). Once I managed to get a very basic help screen, that got me nowhere of use.

The only thing I can get it to do is tell it a:>drive which it chucks a hissy fit as this is not the USB drive and it is stuck at that. Wondering what I've got wrong?

I should add that I've done this using the image of Ubuntu 12.04 i386 Live CD if any of this makes a difference. Any help would be much appreciated.

Solution

Because you created a DOS boot disk with Rufus, but you need to create media that just boots the Live CD or alternate installer, which is different. Please follow the community documentation.

The BIOS is set to load USB first. It loads the USB and shows FreeDOS, and if I ask for C:\>dir it shows me the 5 or 6 files on the USB stick: As follows: FreeCom version 0.84-pre2 XMS_swap etc, etc about FreeDOS Volume in drive C is INSTALL UBU LOCALE <DIR> CONFIG SYS 277 AUTOEXEC BAT 210 AUTORUN INF 224
