  Special thanks to mrjanek for his CD image: http://puru.se/ The bootloader is Chameleon 2 RC4.   After restoring USB image to an USB stick (DiskUtility) you should install the bootloader: (Use DiskUtility (right click, get info) to get rdisk number, in this example we use rdisk0)   - Install boot0 to the MBR: sudo fdisk -f boot0 -u -y /dev/rdisk0 - Install boot1h to the partition's bootsector: sudo dd if=boot1h of=/dev/rdisk0s2 - Install boot to the partition's root directory: sudo cp boot /
