centos bootable usb

Using fdisk, partition your key: one partition, VFAT (type b, and toggle

the bootable flag), about 9M or 10M, and a second partition big enough to

hold a DVD. That should be type 83 (Linux native).

mkfs -t vfat <the DOS partition)

mkfs <the Linux partition

liveCD-iso-to-disk <.iso, w/ full path> /dev/<USB DOS partition>

mount <USB Linux partition> /mnt

cp <CentOS.iso> /mnt/
