Just tried manually creating a disk for 6.3.5 and it still fails. What is confusing me is the fact that When I first tried the trial version in November of last year, the hardware was identical, I downloaded the current version as of November, made a disk with the creator tool and it just worked. No special settings or anything. Now, no disks I make work and I can no longer get my trial drive to boot either.
I just cannot understand why one day it boots and the next it doesn't. I honestly cannot think of anything that changed.
