I was working and needed to restart my Mac pro (late 2007 model) suddenly it stopped and restarted again and so on.

I shut it off and did a safe boot, recovery boot, deleted the P-RAM with ALT+CMD+P+R and nothing works. I can not open my drive to put the install disk.

It just keeps restarting

 

Is my work gone? and what can I do?

    Tthe graphic card as it could easily fail. The 2007 Mac Pro 2,1 came with 7300GT OEM and more than 7 yrs ago when that card was even "new."

     

    You can only do Recovery if you have Lion. So that helps tell us something.

    Can't stress enough, invest in some bootable backup clones.

     

    keyboards and USB cables and devices can cause mischief if nothing else. The fact you could ZAP PRAM/NVRAM (not delete, it can't be, only cleared).

     

    There is no install DVD for Lion, but it is useful to have made your own flash installer wtih the Lion .ESD package.

     

    If you replaced the 7300GT in the past with say Apple ATI 5770, then no DVD exists as you would need 10.6.5+

     

    To open the optical drive door, hold down the mouse during startup. Hold Option key also to stop the boot.

     

    Between TimeMachine and Carbon Copy Cloner and having redundant and multiple backup sets, except for a total meltdown, you have your system and data preserved (and a UPS, we just had a 30 second outage this AM for no good known reasons... all over town).

    Cloning is easy and a great safety net.

     

    Leopard is not supported today.

     

    To get a new graphic card you would need 10.6.x DVD and upgraded first to use the Apple ATI 5770.

     

    You need to find 10.6.8 versions of your software and hardware.

     

    And to use Lion 10.7.5 you have to move to current versions probably, which is more secure and better supported but left support for old legacy programs behind.

     

    Some backup drives and Carbon Copy Cloner will handle the backup/clone safety net.

    you should instead buy a DVD for Snow Leopard 10.6.3 from Apple $20-30 and setup an emergency boot partition.

     

    I would even pull your drives and start with internal drives: one for emergency maintenance and another with 10.6.8.

     

    Later you can use Carbon Copy to copy your old working system to a new drive and keep that handy.

     

    Test your system and in use of 10.6.8

     

    Using anything older than 10.6.8 should be avoided. Maybe if totally disconnected from the internet.

    The main thing 10.6 left behind was no more AppleTalk Printers, and no more Direct execution of PowePC code. The most disappointed users were those running on PowerPC G4 and G5 Hardware.

     

    Mac OS X 10.6 running on Intel processors relied solely on Rosetta emulation to run old PowerPC versions of some Applications. PowerPC support through Rosetta continued to be excellent, and there was very little that did not continue to work. Since it went completely Intel-native, it was more compact and ran faster than the previous versions.

     

    I think you are being skittish for nothing. If you need a way to run your old AppleTalk Printers, I can share several tricks that other Users have successfully implemented, including the solution I use myself.

     

    ------

     

    The leap to 10.7 is not nearly so benign, especially if you are running older software.

    Do you have another hard drive that you can install?

     

    Use Disk Utility from the install DVD to clone your Main System drive (the one that won't boot) to the new hard drive (Using the "Restore" tab).  Then try to boot the newly-cloned copy.

     

    If that is no good, then try a new installation of OS X and see if that boots up.
