    Hello everyone. I am having a problem with my relatively new MacBook pro 17' intel i7. When I start up the computer, a loading bar appears under the apple logo. When the bar is complete I get to the screen where I enter my password. After inputting my password, a white/grey screen flashes momentarily and I am taken back to the password input screen. Restarting has no effect and neither does clearing the PRAM. I tried to start in safe mode by holding the shift key at startup but the loading bar problem still occurred. Please help! It should be noted that I used bootcamp to partition my hard drive and install windows 7 and that operating system seems to be starting up just fine. Thanks again for any help.

    Some additional information:
    1. I am currently running Lion.
    2. Problems started occuring after an update to my Windows 7 OS.
    3. Every time I try to restart after my password/blank screen loop, the screen goes white and I have to force shut down. It may just be me being impatient but I seems to get stuck on that white screen when i try to restart.

    Your Mac partition may be corrupted... which... unfortunately... happens sometimes with Boot Camp. Have you tried repairing the disk via the Lion Recovery partition?

    By the way, if you reinstall Lion using the Lion Recovery, it will simply install onto your already existing installation like an upgrade. It won't wipe your files. So if it comes down to it, you can try that option. Just remember to only reinstall Lion... don't use Disk Utility to wipe the drive or (obviously) your files will be gone.

    Can you even access the Lion Recovery partition? (hold the alt/option key at boot up and select the Lion Recovery partition)

    I would try to run a repair and permissions repair on your OS X partition.

    Do you have a backup at least?

    Tried to install lion in place using the recovery hard drive but when I got to the point where you select which hard drive to install on, the Mac hard drive was not there only the bootcamp and recovery drives which were both locked.
