My Mac Pro boots to Mac OS X Utilities, the Lion installer. I have my internal drive selected as startup disc, but can't get it to boot to that.

Mac Pro, Mac OS X (10.7.4), 2.66GHz dual core Intel

    In that case, use those Utilities.


    Use Disk Utility to check your Hard drive and "Repair Disk".

    Zap PRAM


    Un-select and reselect the drive volume you do want.


    There may be an "EFI Boot" instead of the name when you hold down Option key on startup


    X on startup will default to try to boot from Mac OS X volume.


    Mac Pro can have 4 or more internal hard drives some of which could be boot drive - kept 10.6.8 on its own drive for one thing, or have a clone w/ 10.7.3 on one and 10.7.4 on another.


    you may need to clone your drive. CCC can clone Lion Recovery partition.

    Grant: I repaired the disc, chose my internal drive as startup disc, powered down, and when I booted same thing happened--boots into Utilities. When I restart from Utilities it goes to my internal drive though.


    The hatter, Imma give that a try.

    It's back to normal now; I think zapping the pram did it, thanks.
