Clonezilla PXE Setup

Download clonezilla-live-1.2.8-42-i686.zip and clonezilla-live-1.2.8-42-amd64.zip on a local directory and unzip them. Obviously you can use only one of them.

# wget http://www.kernel.org/pub/linux/utils/boot/syslinux/syslinux-4.04.tar.bz2

# tar xjvf syslinux-4.04.tar.bz2 # cp syslinux-4.04/core/pxelinux.0 /srv/tftp/ # cp syslinux-4.04/com32/menu/vesamenu.c32 /srv/tftp # mkdir /srv/tftp/clonezilla-amd64 # cp […]
