When installing OS X Lion v10.7, I get an option to select the disc where to install it.

My hardisc that is Macnitosh HD is being displayed but when i select it, its displaying that this drive cannot be used to start up your computer.

What should I do?


MacBook Pro, Mac OS X (10.7)

    I have seen this happen when there is a time machine file in the root of your hard drive.

     

    Are you able to open terminal and type the command:

     

    ls -la /

     

    Then copy and paste the result into a post here.

     

    Cheers,
