Hi Guys,

My MacPro will basically not boot into any apple type environment, it boots Vista perfectly.

This started with a disk error on the boot raid volume.

When I boot it panics.

When I boot the Leopard DVD it panics.

When I boot the Techtools DVD it panics.

Not good!

I have looked at all boots in verbose mode and it basically looks like they are all trying to access the system disk even though it is toast, after a while it stack dumps.

I don't mind formatting the disks as I have a backup but how do I get to the point that I can format the disks?

I can boot into Vista perfectly, it can see all 4 hard disks and ntfs/fat partitions on three of the disks.

Any ideas would be really appreciated.



MacPro and MacBookPro, Mac OS X (10.5.2)

    it can see all 4 hard disks and ntfs/fat partitions on three of the disks.

    Two alternatives:

    1. I suggest you disconnect all your drives and see if you can boot from your Leopard DVD. If you can, the 'no boot' issues is obviously being caused by one of the drives. If this is the case, I would try to identify which drive, by connecting just one of them and trying to boot from the OS DVD. Then do the same thing with another drive, and so on. If you are lucky, you should be able, by trial and error, to isolate the drive (or drives) that are the problem.

    2. It does seem that you already have a clue that the system disk is the culprit. You could just disconnect that one and try booting from your OS DVD.

    Did you upgrade the graphics to 8800 or Radeon 3870? That would explain why. Only boot from hard drives, or purchase TechTool Pro 5? and Apple now has 10.5.4 DVDs, but that is full price.

    Create some emergency boot drives.

    Hi Guys,

    Thanks for the replies.

    I have changed the video card back to the original one and I can now boot the install disk.

    Thanks very much for the help you have saved me a long winded call to applecare.

    All the best
