    Seeing as I can only boot into my main drive via Safe Mode which is running 10.6.8, can I upgrade the OS from within Safe Mode to Mountain Lion etc ?

    I think the most important question is, why can you only boot into your 10.6.8 installation via Safe Mode?

    If there's an issue that you've avoiding by booting into Safe Mode, does it make sense to upgrade? You might be better off backing up and wiping your machine.

    That's true, I was going to try an archive install but whatever this problem is the machine also refuses to boot from the install DVD, cannot see this being a hardare issue though as everything seems to work OK in a Mountain lion boot. I have put the install disk in whilst in Mountain Lion and chose install OS, I get the window with the big X and restart option, I clicked on the restart button the machine trys to restart but nothing, you can hear the machine reading the DVD, but no boot.

    Anyway think I will do as you say backup the drive as other than not booting it is all intact OK, install Mountain Lion then copy across what apps games etc I need.

    Personally, that's what I'd do. I'd never upgrade from one OS to another, always best to have a clean start in my opinion. Bit of a pain configuring the new OS just how you like it, but worth it in the long run.

    If your machine can run Mountain Lion it can run Mavericks too, you can create a USB installer with the 'Install Mavericks.app' that downloads, using the following command;

    Code:
    sudo /Applications/Install\ OS\ X\ Mavericks.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install\ OS\ X\ Mavericks.app --nointeraction
    (assuming your USB drive is called 'Untitled')

    You could always try that, might avoid the issue of not booting from your DVD drive?
