My Boot Camp is not working properly.

 

From Win7, I tried to "restart in Mac OS X" from the boot camp options yet when my computer restarted, it logged into windows.

I tried to restart my iMac manually then hold the option button but the Mac hard drive was not there. It only showed the windows hard drive.

    Your Boot Camp is working fine, OSX however is not, if the Mac hard drive is actually missing your machine is borked and you will need to reinstall OSX.

    Sounds like you recently did your Boot Camp Windows installation during which you had to format the Windows partition on the drive, but you mistakenly formatted the entire drive for Windows and lost the OS X system. Unfortunately, the only fix is to reinstall OS X from scratch during which you will need to repartition your hard drive. You will lose your Windows system which you will need to redo once you have reinstalled OS X.

     

    What version of OS X were you running?

    In Windows (what else?) right click on Computer, select Manage, go to disk management and tell us what is reported, best would be to take a screenshot and post it here, you should see an 750G partition that is not NTFS.

     

    Post back.

    The second partition in your list (drive E;) is the Mac partition, but it is broken (or you would be able to see it in Boot Manager) I think that you are going to have to reinstall OSX but if you can't select that drive it's a do-over, so back up all data in all accessible partitions and start again.

    Selecting drive E: in Windows has nothing to do with reinstalling OSX, in which there will be No Drive E: As for your files unless already backed up they are at risk. Right now you are unable to boot into OSX but can you boot into the recovery partition (reboot, hold cmd-r at the chime, tell us what happens).

    I was able to load up recovery partition, and I am accessing safari from here too. Background is all gray and tried to verify and repair, it says that my Mac OS drive is corrupt. What should I do in this partition?

    Reinstall Lion from the Recovery Partition, your applications and your data should not be affected, once you have done this buy an external drive and a copy of Carbon Copy Cloner and use it to make an incremental clone of your drive, and then back it up as often as you can!

     

    If Lion can not install then there are 3rd party utilities that may help, if not, an erase and reinstall is going to be the last resort.

     

    If you had made a clone before this happened you would have been using the Mac partition long before this thread got this long.

    It cannot re-install itself since the Mac HD Partition is "Locked"

    I can't tell you what to do but I would be erasing the drive and starting all over from the beginning, but I would also have backup, sorry.
