MAC mini 2011 model wchih came with LION preinstalled.


Wanted to reset it back to the Factory setting as given in the document provided.


From the Mac OS X Utility


1. Erased the Hard drive as specified from the Disk Utility


2. Selected Install a new copy of Lion, which starts a download of about 3.76 GB and displays 5Hr 50Mins pending to complete.


3. After about 4 hours it complets the download and in the recovery log it says Validation token Timeout and Validation failed.....


As I have Erased the HDD to do a facory default there isn't an OS present in the Disk but my question is how should I further proceed with the installation ?


There are no good documentation from apple given for this thing !



Can someone give me some light on this or should I take it to a Apple care ?


PS: Tried both in Wifi and in Ethernet.....

    Have you reviewed: OS X Lion- About Lion Recovery?


    Boot to the Recovery HD:

    Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.


    Try this first as you can simply reinstall Lion directly from the main menu. However, if you cannot boot to the Recovery HD then you have several other options suggested in the above link.

    I tried booting from the recovery partition and followed the steps to install.  Lion recovery downloaded everything it needed (took about 4 hours) and restarted.  Once it restarted it didn't automatically boot into the recovery partition as I expected, and instead showed the No OS icon.  I rebooted with COMMAND+R and it said "INSTALLING" for over 1.5 hours.  I suspected that something was wrong so I restarted the mini and tried booting with COMMAND+R again to start everything over, however now when it boots to the recovery it just says "Installation Failed Try Re-Installing"  But there is no option to re-install.
