    I had windows installed in a partition on my iMac but removed it and left the partition there. Now I've just come home to find my iMac was shutt off ( I always sleep it) and when I boot it up it auto loads the missing windows OS and if I hold the option key the mac OS is nowhere to be seen please help

    That doesn't seemto do Anything it still goes straight to the missing OS screen from the windows partition

    Are you sure you deleted the right partition?

    Boot from the OS X Install Disc 1 and Repair Disc from Disk Utility.

    Okay so I think that the OS X partition became unmounted somehow.. When I try to run first aid and verify it it fails and says..

    **/dev/disc0s2
    Invalid BS_jmpBoot in boot block 000000
    Error: filesystem verify or repair failed

    Did you repair, or just verify?

    BTW, don't bump threads.

    Do you have all your important files backed up?

    It might be best just to reinstall OS X through either an Erase and Install or Archive and Install.

    Install OS X on an external hard drive (free volume or partition is needed).
    Use that to boot from, and see if you can see your internal Mac OS X volume.

    If not there are several applications to help you.

    DataRescue II for example helped me quite a lot in the past 4 years with unrecognizable volumes. It restores the files on such voulmes and copies them wherever you want to.
