If you are having difficulties burning and booting an iso or img file from a usb drive, try this method.

But first I recommend that you download your iso or img via torrent, to prevent corruption if possible.

Open a terminal and type:
Code:
cd /home/YOURUSERNAME/Downloads
Replace USERNAME with your username, and Downloads with the folder in which your iso is located.

Then, with the usb drive inserted:
sudo fdisk -l
To detirmine when your USB drive is mounted (for me it was SDB)

Then:
sudo dd if=NAME OF ISO of=/dev/sd[REPLACE WITH THE RESULT OF PREVIOS STEP]
DO NOT, I repeat DO NOT, enter something like sdb1. Because it will not work, you have to use the root of the drive. Which would be sdb instead.

This guide comes straight for mips, I just thought I'd post it for everyone to see, I take no credit.
