For small OS images you can sometimes get away with loading the whole thing into RAM on boot and then running from RAM, which essentially removes the boot drive from the equation completely except for that initial copy to RAM. I always pick this option when I use Clonezilla because usually I'm booting it from a USB stick and everything would be slow the whole time if I didn't put it into RAM.
