Here's a complete script - anyone, *please* feel free to test it, and let me know if I've missed anything.

Thanks in advance.

If you don't want to jump through the hoops required to become a Wiki author, let me know and I'll be glad to add it with attribution to

Variation on your theme. Uses ext2 and extlinux with no FAT partition. Remove "-n" from sfdisk so changes are written. Adds some error checking.: ---------------------------------------------------------------------------- #!/bin/bash # ################################### # Author: mark roth # Date: 30 Apr. 2010 # Purpose: to create a working, bootable CentOS install on a USB key #####################################

PATH=/sbin:/bin:/usr/sbin:/usr/bin

if [[ $# < 2 ]]; then echo "usage: $0 <devname> <path/to/install.iso>" echo " Example: $0 sdb /scratch/CentOS-5.4-bin-DVD.iso" exit 1 fi

if [[ ! -f /usr/bin/livecd-iso-to-disk ]]; then echo "You must install livecd-tools before running this." echo "See: http://projects.centos.org/trac/livecd/wiki/GetToolset" exit 2 fi

if [[ -f $2 ]]; then if file $2 | grep -q "ISO 9660"; then echo "Using ISO image $2 ..." else echo "$2 is not an ISO image!" exit 3 fi else echo "$2 ISO image file not found." exit 4 fi

if [[ $EUID -ne 0 ]]; then echo "This script must be run as root." exit 5 fi

if sfdisk -l /dev/$1 >& /dev/null; then echo "Current partitions for /dev/$1:" sfdisk -l /dev/$1 echo -n "Press <Enter> to continue or ^C to abort: " read aline else echo "No such device /dev/$1" exit 6 fi

sfdisk -uM /dev/$1 << EOF ,,83,* ; ; ; EOF

echo "Remove and reinsert the USB key." echo " Use Safely Remove first if in a GUI." echo " Do not mount in GUI after reinsertion." echo -n " Press <Enter> to continue: "

read aline

mkfs /dev/${1}1

/usr/bin/livecd-iso-to-disk --reset-mbr $2 /dev/${1}1

echo "USB boot media of $2 done."

# end ---------------------------------------------------------------------------- Unfortunately the only system I have to test on at the moment boots the installer OK, then asks for the installation media, but doesn't see the USB device when Hard Disk is selected. With the FAT partition and syslinux doesn't see the device as bootable at all.
