I have been having trouble booting my macbook pro. I have a backup of everything on the cloud so I tried reinstalling the system from my usb mountain lion stick. Unfortunately the disk utility did not want to reformat my HD and I ended up removing the HD placing it in a hard drive enclosure and proceeding to reformat/reinstall the system. This boots fine from the usb but when I put it internal I get stuck on the boot screen with the apple logo and the spinning lines below.
I tried booting in safe mode and this is the output I got this:
Anyone understand that output?

Strange indeed!
It runs from USB but not when you put the hard drive back in the computer?
In any case check your disk for problems.
But it could be just the flat cable connecting the hard drive to motherboard !
