It is possible to do this, but is very shaky because it very much depends on your bios support for booting from a usb key. The better way to do this is to just either setup a PXE boot server with support for this vmlinuz/initrd.img: http://mirror.centos.org/centos/5/os/i386/images/pxeboot/ (you pick your version for "5", and your arch for "i386" ... then download off the mirror servers ... then add a "linux rescue" when booting from that on PXE. ===OR=== you can put those vmlinuz/initrd.img files on all your servers (somewhere in /boot) and create a grub entry on all the machines that have the kernel line: kernel /path_to/vmlinuz rescue initrd /path_to/initrd.img You will then need to have a tree to point to via a network install. This method works on all centos servers regardless of whether the USB key can be booted from or not.
