    Hi

    installed Yosemite...decided to role back

    Problem with backup, decided to go into disk utility and restore form there...

    Now have serious problem...

    I can do nothing in disk utility

    Cant erase Yoesmite disk, cant erase my disk to start,

    Try to re-install OSX but it cant find a disk

    When I try to restore, it only shows a rescue disk...

    I cant delete partitions, or erase disks..

    The machine keeps booting into disk utility mode over and over...

    Any help welcome...

    How did you install Yosemite? Can you boot into recovery partition? Can you get an OSX install disc, either DVD or USB?

    You can't install Mavericks over Yosemite. You have to erase the volume first and you can't do this while booted from said volume. You could boot into recovery mode but it will only offer you Yosemite to re-install.

    You shouldn't have installed Yosemite on your main partition if you weren't sure you were going to stick with it. It's in GM now so I'd recommend staying put. If Yosemite is currently hosed as a result of your attempts to restore you can boot into recovery mode and re-install it by holding command-r on startup.

    If you insist on rolling back follow the guide here:

    Hi

    I am happy to keep using it, but when i Command R to re-install it I get Disk Utility and click Re-install, when it ask where do I want to install it only gives me the recovery disk, and says that this is locked..and says it cannot be installed on Recovery HD.

    I though I had partition it..but obviously not

    My prob is also that I cannot erase any disk in Disk Utility

    I have booted form a boot disk, but still wont allow me to erase or re partition any disk

    Is the original Yosemite partition visible in Disk Utility? What happens when you try to erase it?

    And to be clear, it is the volume you are trying to erase, right? Not the entire disk, because that won’t work since you are booted off the recovery partition.

    You’re in the wrong drive. You need to click on Macintosh HD. See if you can repair or erase from there. You’ll need be booted from an external boot disk.

    OK...

    So I restore over the internet , this cleared my drive, I renamed it, and erased it.
    then went into restore OS, it found my "New" drive and is currently installing OSX on new HD

    Phew...

    Lesson learnt, create external partition

    Well....

    After getting everything working again, I went into Migration Assistant to restore everything.

    Then I was told by the Mac

    Volumes Not Found...

    anyone know how I can restore my info.

    I have name the HD the same and on the NAS, I can see the sparse-bundle file

    But neither Time machine nor Migration assistant can retrieve any data

    Any ideas?

    Was the sparsebundle created in Yosemite and you're trying to restore it back to Mavericks?

    I have restored back to Mavericks, but there was a backup done in Yosemite...

    I have done a Mavericks backup before the Yosemite upgrade

    Would I need to go back to Yosemite to do backup ?

    On iOS backups aren't backward compatible, so you can't restore an iOS 8 backup to a device running iOS 7. Looks like the same might be happening here. I'm no expert but I think your data is stuck unless you restore it all back to Yosemite.

    Oki Doki.....

    so, the problem doing a restore or doing a migration assistant restore was basically due to the fact that my NAS seemed to have an incomplete backup that was preventing a restore

    the fix...reboot the NAS

    and as we speak she is 20% restored

    I have learnt a huge amount about all this stuff this week.

    thanks for all the input from everyone here and even more thanks for not doing the....you shouldn't be downloading betas.....yada... Yada

    I was thinking of writing it up as a "how to" type thing

    would it be worth doing ?

    This made me smile. It's so annoying when people do that!

    Glad you got your stuff back!
