I erased the HD in Disk Utility (tried to erase the one with all the numbers but got the message "unable to unmount") and then used a disk to intall 10.6 but this didn't work, forgot the message I got but it wasn't allowed.  My goal is to go to 10.7 wich I purchased in the Appel store. Does anyone know how to do this?

    Is this a brand new iMac?

    No, it's from 2011.

    You need to determine which version of Lion was installed on the iMac at the time of purchase.

    This is confusing. Your topic says you want to revert to 10.6, then inside you say 10.7. So which is it? Use this to determine which OS your computer shipped with. You might be able to run 10.6, Snow Leopard.

    My computer was shipped with 10.6.2. So I guess that explaines why the 10.6 disk didn't work.

    If it the Mac was from 2011, and if it had Snow Leopard, it would have come with 10.6.7  and you can't use the Retail DVD, which is 10.6.3. You would have to call Apple and ask for replacement discs.

     

    And if you are trying to use the DVD that came with another Mac, that might be why it's not installing.

    I have no idea why you want to revert to Lion, and this is getting very confusing since the information you keep giving is very unclear. I'm tempted not to post anything more, but I'll give this one more shot. This would be to get back to 10.8, which you appear to have been running before you erased the drive.

    Getting back to Lion from Mountain Lion is either impossible or extremely complicated. I don't have an answer for that one.

     

    But you can get to Lion from Snow. If your Mac is from 2009, then the 10.6.3 retail disc or the disc that came with the computer should install. And then, maybe, you can find the Lion you originally purchased registered to your Apple ID at the Mac App Store. But you should know that if you go this route, you will lose all your user data, since the drive will need to be completely erased before installing Snow. You should make a backup on an external drive before doing this, that is if you haven't already lost all your user data.

     

    That's all I know. Perhaps if you bring your Mac in to an Apple Store they will help you out there.

    You will see from reading this rather long thread that downgrading back to Lion if you didn't make a backup before the upgrade is either impossible or very difficult.

    I've already given you a link to instructions for downgrading back to Snow Leopard, but maybe it would be best for you to try to address the problems with Mountain Lion, since that might prove to be the least difficult approach to this.

     

    I think you should post a new topic directly in the Mountain Lion forum. You should give full details of your Mac, including how much RAM you have installed and the problems you have been experiencing. Do not include your serial #. If you can get ML to work properly, it may be a superior OS to Lion.
