Hi there, after years of tweaking can't work out this one:

1) Bumped a MacBook HD to 250 GB
2) After non booting clone wiped clean and virgin installed
3) Sys will not boot, bezel then stop sign

When taken out of MacBook into External FW case, it boots fine.
When back in the MacBook, I can startup another MacBook Pro with target mode!!!
Old sys starts fine.

I'm starting in Verbose, I'm getting two no kernel dependency errors (Keyboard and KeyEventDriver).

Doesn't make sense.

Any ideas?
