Just downloaded the Lion Recovery Disk Assistant, and upon launch, I get the error:


"The Recovery HD on this computer is damaged or not present. Recovery Disk Assistant requires a functioning Lion Recovery HD to create an external Lion Recovery."


This is a Lion install from the App Store -- no mods. What now???

    An install... how?


    Does the Recovery actually work if you try to use it?

    Same problem here, tried to search for a solution, but no use.

    Actually I DO know that Finder/DU does NOT show the Recovery HD partition, this is no problem.

    However when I press ALT/OPTN when booting, Recovery HD does NOT show up.


    Reason: if you manipulate paritions and/or do a clean install from a bootable external media the Recovery HD gets deleted and/or does not get created at all.


    So I am in the same camp as others, seeking a way to create a Recovery HD parition on my one and only, built in HD (not on an external media!), the same one as  Lion installer created or should have created in the first place.


    Thanks to everyone who may help or at least provide some guidence.

    Recovery doesn't work fo me, either. I'm in the Dev program, so this is the Golden Master install -- but that shouldn't be making any difference.

    Have you tried to create one in another mac?

    It should be worked in yours with that

    I'm talking about the recovery partition that was supposed to be created when installing Lion. I hsould be able to startup THIS computer into the Recovery partition, but the Recovery HD on THIS Mac is mysteriously gone.


    I know I can create a bootable 10.7 DVD and install from there -- but I want to fix my Lion install so that the Recovery HD is active like it's supposed to be.

    Tech Note HT4649 says:



    During installation, OS X Lion may display the message:

    "Some features of Mac OS X Lion are not supported for the disk (volume name)".

    Products Affected

    OS X Lion

    Why does this message appear?

    This message means the installer cannot create the Recovery HD partition on your hard disk. Recovery HD offers on-disk recovery tools, allows you to restore from Time Machine backups, reinstall OS X Lion over the Internet, or set a firmware password. Recovery HD is not needed to install and run OS X Lion, nor to access most of its capabilities and new features.

    Usually, this message appears in one of two scenarios:

    • The disk you are installing Lion on is a RAID volume"



    My main startup volume is a mirrored RAID, so maybe that's wht I don't have the Recovery option...?

    I just called Apple on this same problem.  They advised that you cannot create a new Recovery HD without doing a fresh install of Lion.  My new iMac does not have the Recovery HD and it came with 10.6 media.  If I want to create an external Recovery HD my options are:


    1. Wipe the computer, install 10.6, and upgrade to 10.7

    2. Install Lion on an external drive and use that as the source for the external Recovery HD

    3. Run Recovery Disk Assistant on a computer with a working Recovery HD


    I'm going to use option 3 and take my USB thumb drive to the Apple store and have them create a Recovery HD on my drive.

    The recovery tool didnt work for me either. I might just go the apple store and create the recovery image there.

    Simply reinstall Lion on top of itself. This will recreate the Recovery HD partition. It has always worked for me. And it's the only way I know of to get it back.


    Since my MBP has a Recovery HD, the Lion Recovery Disk Assistant worked nicely. I partitioned a 4GB USB SanDisk flash drive with 1 partition 700mb and the other partition for the rest of the space. Used the assistant and it created the Lion Recovery HD on the 1st partition of the USB SanDisk. So, if you're using a USB flash drive larger than 1GB, you might want to partition it so you don't waste the whole drive. Otherwise, the assistant will use the entire drive.

    How did you reinstall Lion on top of itself?  I tried using the option key to launch the app store and reinstall but it came back with a message about my current version being newer.


    To get my recovery usb created I installed my copy of 10.6 on an external drive and booted to that.  Then, I downloaded Lion from the app store.  I upgraded my 10.6 install on my external drive then used the Recovery Disk Assistant to make my usb drive.  I also used the Lion package to make an install dvd since I had the file handy.


    It was faster than driving to the Apple store, but it sounds like I'm missing something and a reinstall of Lion would have worked too.

    I used a Lion install DVD that I created from the InstallESD.dmg file found in the downloaded OS X Lion Application. Rebooted then pressed C when I heard the boot chime. The system rebooted from the Lion install DVD and I started the install. You can also reinstall on top of itself by clicking on the saved InstallESD.dmg file while in Lion instead of rebooting from the install DVD. You can execute the Install Mac OS X file.

    keg55... I didn't have a DVD.  I didn't know about the InstallESD until after I upgraded and I think the install package is removed as part of the upgrade... or at least I couldn't find it.
