I'm hitting two main issues right now:

• First time I tried it, it crashed on the restart, because asr didn't rebuild the dyld cache. We've seen this before.
• Now I can't even get that far. It won't let me complete the authorize users/set owner process.

When you did it, did you try to restart by selecting in the System Settings? Or did you just reboot and hold the power button to choose a different drive?

Did it ask you to authorize a user and select an owner?
