    Install OS X Using Internet Recovery

     

    Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.

     

    Boot to the Internet Recovery HD:

     

    Restart the computer and after the chime press and hold down the COMMAND-OPTION- R keys until a globe appears on the screen. Wait patiently - 15-20 minutes - until the Recovery main menu appears.

     

    Partition and Format the hard drive:

     

    1. Select Disk Utility from the main menu and click on the Continue button.
    2. After DU loads select your newly installed hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
    3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed. Quit DU and return to the main menu.

     

    Reinstall OS X: Select Reinstall OS X and click on the Install button. Be sure to select the correct drive to use if you have more than one.

     

    Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

     

    This should restore the version of OS X originally pre-installed on the computer.

    Kappy, thank you for fast reply.

    It looks this solution doesn't work for me. Maybe because there is no partitions on disk.

    Do you have any other thoughts?

    What specific model Mac Mini?

    The 2011 and later have internet recovery

    The 2010 only had internet recovery if the EFI firmware was updated.

    Computers that can be upgraded to use OS X Internet Recovery - Apple Support

    If not Internet recovery you will have to either download the Yosemite install from another Mac and make a bootable USB install device using

    DiskMaker X

    and boot from that

    Or use your Snow Leopard install DVD and install and fully update and then go to the Mac App Store and download and instll Yosemite

    This is late 2014 model.

    No startup key combinations for Mac works apart from Cmd+Alt+P+R. If I insert bootable USB dongle (Win 10 setup)  it doesn't boot either from it nor from Windows partition - black screen.

    I converted MBR to GPT using Partition Assistant and tried to set another partitions like in this article. Nothing changed.

    In my Opinion, there should be at-least a bootable partition to restore data back from Recovery HD. Since you wiped it there is none. If you have clone copy of Macintosh HD, Recovery HD then you can easily restore the files from it. I suspect you have one?

    What happens when yo boot with Command + R (to Recovery)?

    What happens when yo try to force your Mac to boot into Internet Recovery by holding down Command+Option+R at startup.?


    Use a known-good wired KB if you are not already using one. Make sure it is directly connected to the a USB port on the Mac
