Just download a live linux cd, such as: http://ftp.uni-kl.de/pub/linux/knoppix-dvd/KNOPPIX_V7.4.1DVD-2014-09-15-EN.iso along with checksum files: http://ftp.uni-kl.de/pub/linux/knoppix-dvd/KNOPPIX_V7.4.1DVD-2014-09-15-EN.iso.md5 http://ftp.uni-kl.de/pub/linux/knoppix-dvd/KNOPPIX_V7.4.1DVD-2014-09-15-EN.iso.sha1 Once you burn it to dvd, boot it, and use the gui to launch a terminal (icon for it is at bottom left bar). then you run su - then you insert the usb stick. Assuming there is only one HD in the machine, the stick will be named /dev/sdb If more than one HD in the machine, say 4 HD (sda, sdb, sdc, sdd), then the stick will be sde. Run dd if=/dev/zero of=/dev/sd? bs=1M where ? is b or c or d ...etc depending on how many HD's you have in the system. You do not need to specify the count, because dd will stop when the stick is full of zeros. Once done, unplug the stick, and reinsert it. then run the command fdisk /dev/sd? (? as explained above) create 1 partition. set it's type to whatever you want. I usually use the letter c as the type to mean fat lba. To finish, type the command w to the fdisk session and you are done. Now type fdisk -l /dev/sd? and you will see the drive has 1 partition. now create a filesystem on your drive: mkfs -t vfat /dev/sd?1 (again ? as explained above). type the command reboot and the dvd drive will get ejected. press the return key to boot into your normal HD. The stick is now useable and mountable.
