As some of you may know there is a pretty popular free bootable cd \ USB for diagnostics and repair called Hiren’s Boot CD Hiren's BootCD 15.2 - All in one Bootable CD » www.hiren.info It uses mini win xp as “temporary” os, but CCE doesn’t run there.
I thought it would be a good addition to that boot CD, just in case your main OS fails to load.
