  1. I installed a new SSD in a late 2008 13" Macbook 5,1. I created a bootable USB following this video. When I restart and hold option to boot from the USB nothing happens (gray screen remains gray). When I insert this same USB into my newer (Mid 2011 MacBook Pro) MacBook and attempt to boot from USB it displays as a boot option.

    I also have a bootable OSX 11.11 on different USB that shows as a boot option in the older MacBook (unfortunately that OS is too new and won't run on the old com) so I'm completely lost as to what the issue is. Any insight would be greatly appreciated.

  2. Erasing USB with GUID scheme makes UniBeast say "I need at least a usb of 7gb hfs-partitioned", but if I erase it with MBR scheme it detects it normally, does MBR erasing have any problem in the future ?

    Note: my usb stick is 8gb

  3. I have el captain and my disk utility is completely different, I dont get the options you present!?
    What OSX are you using?

    Thanks for the help….

  4. Hi man! My OS is Snow leopard 10.6.8, when I follow the video steps I see this error: "Failed to start erase of disk due to error (-9999, 0). A error occurred erasing the disk." what's up? Can you help me please?

  5. keep getting the below message. any ideas? using an 8gb flash.

    Erasing Disk: 0%… 10%…
    Error erasing disk error number (-69888, 0)
    A error occurred erasing the disk

  6. Having difficulty getting the flash drive to allow partitions. Erase at what security level? I already erased at 1st and second levels – trying the third one now.
