I downloaded and installed Lion 10.7.2 update last night on my Macbook Pro The update appeared to download fine after a while, but during installation of the system that seemed to hang the file transfer. I left the installation system overnight, but when I saw this morning the update was not completed and I was not getting any response from the system at all.
Now when I reboot I get the Apple logo with the state setting symbol, but that's all. I booted in verbose mode and it seems as if the starter is hung on the Bluetooth driver installation. I can get into the Mac OS X Utilities and was thinking reinstalling MAC operating system, but I am sure of this as I do not know if this will wipe out all my data. I am moderately original to the Mac troubleshooting so any advice would be very much respected.
