Backup successful - unable to boot
On a brand new mid-2009 15" MBP, installed Snow Leopard and applied all updates as of last night (11/10/09). This morning, connected an external drive in enclosure via USB and performed a full backup. Success!
Turned the system off and rebooted off of the external USB drive. Success!
Swapped the external drive with the internal drive, disconnected everything except power and rebooted. See the Apple logo and the spinning progress indicator, unable to boot.
Did everything mentioned above twice with exact same results.
Any pointers?
