Mac Pro 2008 won't boot from install disc - black screen

I recently purchased a new hard drive to replace the original that came with my Mac Pro 2008.  I was able to format the new drive using Disk Utility. I am now at the point where I need to install OS X onto the new drive, but the computer refuses to boot from the disc. The disc is recognized by the computer (I can access the disc and am able to use the BootCamp applications, etc.) but I just get a black screen when trying to boot directly from the disc. The computer boots fine otherwise.


I have tried the following:


I have tried using both the gray install disc that came with the computer and the Snow Leopard Install DVD disc.


I have tried booting using the "C" key and the "option" key but still receive a black screen following the chime (I've held these down for several minutes).


I have tried restarting from either install disc using the Bootcamp Assistant.


I have tried running the installation software to get it to restart from the disc.


I have tried a combination of the drives, i.e. trying to boot from the discs with just the new drive installed, just the original drive installed, and with both in bay1 and 2.


Everything results in the computer starting up, hearing the chime, and then nothing..just black screen. I have the original drive partitioned with BootCamp with OSX Snow Leopard and Windows 7 installed (I don't know that that matters).



I am at a loss as to what to try next. It doesn't seem like the superdrive because it is recognizing the disc, it just won't boot from it.


Any help is appreciated, thank you.

    What graphic card? did you replace the one it came with?


    How about picking up a copy of 10.6.3 DVD does not support the 5770, only works with 10.6.5 or later.


    Did you or can you still boot from the old drive and clone your system to the new drive for now?


    Can you still boot Windows 7? it tends to only like the drive bay it was in, whether than be "0" or one of the others. There are tools like CampTuneX, to clone Windows to another drive but it really is ideal to have Windows on its own drive.


    Why do you want to do a clean install? or maybe it is time to consider Mountain Lion now instead?

    Clone should be a must  and easy to do and learn (learn by doing! 2)


    6800 would 'qualify' as 5x70 series flashed etc and same rule: 10.6.5


    In the past there was 10.4.6, 10.5.6, but not 10.6.6 - even though strong need for such a DVD.

    10.6.8 DVD would  be excellent


    Lion or ML - buy, download, make an installer flash card would be what I would do at this point.


    Then keep both - dual boot as you learn and test and see what ML does and waht you had that required Rosetta to support PowerPC. See about that.


    With Carbon Coyp Cloner - was share, now commercial, great utility been around since 10.2.2 at least - this time 2003. 10 yrs.


    You can clone the system folders, you can even selectively choose. You can skip copy of most of your home account and do that separately to another drive if  you want.


    Clone Windows with Paragon or WinClone and use Windows 7 or 8 DVD to do a system repair (automatic) or to edit the BCD file. It can and should - and all you do is boot Windows 7 DVD w/ only the one drive present and go at it. Piece of cake. But yes, Windows gets fussy if you change or remove or move. BCD to the rescue. A proper program for cloning like Paragon's "Clone OS" meant for going from disk drives to SSDs, knows that and how to do it.



    Back to how to clone etc:



    Disk utility has RESTORE which will also clone your system but not the Lion Recovery partition. Oddly  Apple did not 'endorse' making bootable clone of the system which works too but most choose Carbon Copy Cloner - it works more consistently; it allows for smart update of the backup volume. Both can backup to a sparse disk image if desired.


    Using Cloning as a Backup Strategy

    Create an OS X Lion Install disc tallation-disc


    How to clone your system: ckup.html


    The DVD is dependent on your hardware. And your hardware changed. The drivers for the 5780 and 6xxx are bundled in the OS and lacking. Minimum build thing.


    Put the new drive anywhere you want. Does not matter. Can move it later. Can be drive bay 0-3 or a Firewire external or under the DVD drive.


    When you clone pull the old drive and boot from the newly cloned.


    After that keep a backup clone around all the time. Takes less than 10 minutes to do a smart update to copy just the changes to keep it current. So you have working copy of the system. I keep Clone "A" that I keep "as was" the system as of last month or whatever (like 10.7.4 before upgrade to 7.5).


    Comes easier after doing it once and have all your ducks in a row.

    One thing at a time.


    1) yes. your 6xxx won't (it will boot an OEM DVD to the Apple Hardware Test that is not an OS and is basic VGA w/o any drivers.


    2) I never said to clone the whole hard drive etc. Just clone Windows to its own hdd. Or do a clean install of Windows (which might be the wisest esp. if it has been 3 yrs).


    3) don't boot and run Windows natively (Boot Camp) unless you MUST and need to. A lot of users find that they can use their Windows partition instead in Parallels for Mac as a guest OS (VM) running under (side by side ish) and not have to dual boot at all.


    Only games, 3D need to. So you might want to check out Parallels ~$60 and their support and reviews.

  might have some feedback from users, reports, issues, about it and VMs in general.
