Make a USB Boot CD for CrunchBang Linux

The following tutorial will enable you to create a USB Boot CD that can be used to Boot CrunchBang Linux from a USB Flash Drive on systems that do not natively support booting from USB. The USB Boot CD uses a grub bootloader to launch the vmlinuz kernel and initrd from the CD, loading the necessary USB drivers, and then proceeds to locate and extract the compressed filesystem from the flash drive. CrunchBang Linux is a unique remix based on Ubuntu.

USB Boot CD for CrunchBang Linux creation essentials:

  • PC with a BIOS that does not support booting from USB
  • CrunchBang Live CD
  • Working CD Drive and USB Port
  • Flash drive with CrunchBang preinstalled
