    Hi, I have a MAC PRO and sadly my old hard disk died. I have tried repeatedly to install OSX to a new hard disk and whilst the install is successful, when it reboots, it hangs. So I force the restart and nothing happens, it does not find the hard disk where the installation took place.

    I have tried holding down alt key, still no joy. All it finds is my DVD with the install disc for snow leopard!

    I have tried booting from a USB to install Mountain Lion. Still no joy.

    I have tried holding down command, option, P&R to try and force a reboot, all that happens is it plays the reboot sound and then cycles through it again and again and agin.

    If I remove all Mac disks and replace the Hard disk with a Windows 7 hard disk (previous install), it boots up after holding alt key and selecting so the machine is OK it just can't see the Mac disks.

    Any suggestions gratefully appreciated.

    sounds like the new hard drive is bad. However When you installed, did you make sure to put 1 partition, and use GUID, also format using MacOS extended journaled?
    Intel macs need to use GUID partition table to boot.

    The new SSD is good, it performs as expected but no I did not have access to the MAC at this stage so it would have been formatted as Windows disk.

    So is there any way to recover this, for example would this work?

    Clone drive
    Format SSD as above
    Clone drive back

    Would that retain the format?

    Thanks.
