    How about telling us what issues you're having? Maybe we can help you resolve them rather than reinstall Lion.

    You can gain access to the Recovery partition by holding down the option key during boot up and selecting Recovery. From Recovery you can then run Disk Utility to erase and reinstall Lion if you choose.

    the main issue I'm having is when i unplug the computer from the power source so its running on battery only, it slows wayyyyyyyy down. every thing i do with it lags really bad, scrolling in a browser, opening and closing applications. or even just click on a button.

    i would really just like to more or less restore it to factory default. i don't really have anything that I'm worried about losing on it.

    See my first post. You reinstall Lion from the Recovery partition not on it. Boot into the Recovery partition and select Disk Utilities. Use Disk Utilities to erase your hard drive and format it for Lion. After which, download and install Lion from the App store. You don't have to pay again.

    What chscag is trying to say is you don't erase the recovery partition. The message you're getting about can't unmount, is (nearly) always about the drive you started up from - the recovery partition. You don't want to erase the recovery partition. You want to erase the normal startup drive/Volume.

    Your responses don't make it clear, so we've been repeating here.

    okay well i clearly dont know how to do what you are asking, is there somewhere i can read on exactly how to boot up to get me to where i need to be? how else do i get to the erase part without booting in recovery? if i boot up normaly i can erase it because thats the disk i booted from.

    Please, we're not trying to trip you up here. It really sounds like you want to delete/erase the recovery partition (not correct thing to do) - instead of the normal startup partition.
    You do know that installing Lion puts two partitions on your Mac - a startup partition (the majority of the hard drive), AND the recovery partition (a small partition - I guess about 5 GB)?

    Yea I understand that. So you said that's probably not what I want to do, do you have another suggestion? I really do appreciate the help.

    Okay I read your post wrong. I don't want to erase the recovery partition. I understand what the confusion is. I really just want to completely wipe out my Mac and start it back like I just bought it (if possible).

    OK - you need a different boot source. Did you make a bootable USB flash drive? Or, do you have a 10.6 DVD to start from?
    You can't re-partition or erase a drive that you boot from.

    To be sure - you know the recovery partition takes the place of a DVD for Lion? It is the installer and Utilities disk.
