OS install, can't access partition in disk utility

I replaced the HD in my '98 macbook penryn model, then I accidentally loaded a Leopard upgrade DVD instead of the grey install disk to re-install my OS. I followed the instructions for formatting the drive in disk utility with the wrong disk, then when I tried to install realized my mistake.

Now I am using the right disk but the computer doesn't recognize the HD as a location to instal, and I can't access the partitions tab in disk utility to check formatting/re-format. I get the message "disk utility has lost connection with disk management tool and cannot continue. Please quit and relaunch. The partition scheme is now listed as "master boot record"

I have tried restarting holding down 'alt' and also 'c' with no results.

Try starting from the Leopard upgrade disk, "C" key. Try the partition with it and do the GUID partition.

Everthing looks good with the upgrade disk: GUID is set, and there is 1 partition that I named Mac HD. But now what? I can't install from here, "mac os x cannot be upgraded to v10.5 on your computer. mac os x v10.4 or later could not be found on your computer" Thanks!


Now go back to your original installation disk, if it's the one for this machine, and install your system. Next use the upgrade disk to upgrade it.


What is the best way to switch the disks? I can't eject using the eject key; the only way I was able to switch the disks so far was ejecting by holding the mouse key with start up... And then loading the original, do I need to hold anything down during start-up? This switching disks business is how I got stuck with my original problem in the first place...

(and I do have the original install disks)


Hold the mouse button on startup to eject.


Then hold "c" again for start up with install disk?

If you are not able to access volume in your Mac, you must use some third party tool, which works effectively. I am using Stellar Partition Manager tool to create, format, delete, resize my Mac volume, it is very easy to use and reliable. I am sure if you could use this tool you will definitely format/re-format your Mac volume.
