    Hello all

    I have a little problem that i need some advice on if you'd be so kind;

    So... i tried to install Ubuntu (don't ask me why) onto my G5 dual core 2.5 Ghz PowerPC and after the instalation not working as i had hoped (it worked fine on my netbook btw) i switched off the mac using a hard-shutdown from the power button as the whole system became completely unresponsive.
    I then tried to reboot and found that on my reboot rather than booting into the user screen as per usual i got the dreaded "circle with a cross through it" ø. After fiddling about with a hell of alot of boot options i managed to get into the open firmware (option,o,f) terminal style screen up. from this screen it would seem that on my internal hard drive that pretty much all of my files are still on the hard drive.
    As i couldn't open them from the open firmware i was then told by a friend that i could run disk utility from the install cd provided with mac os x and i managed to find my internal hard drive using disk utility.
    It seems as though during the ubuntu install i've deleted all partitions on the hard drive and therefore on the "partition" section under "current" it has no partitions set up and i have the option to set one up. It also gives me various different formating options; Mac os x Extended, Mac os x Extended (journalled), Mac os x Extended (Case sensitive journalled), Mac os x Extended (Case sensitive), unix file system and free space. i think it was originally on Mac os x Extended (journaled) but I'm not certain.

    Before i hit that re-partition button do u think that this is the right thing to do and if so which formatting option should i use? Presuming that the re-partitioning goes well, will i then have to re-install os x?

    Also will i loose all the data on the hard drive? Although i have the vast majority backed up there are still a few odd files that i wouldn't mind keeping if at all possible and obviously i didn't think to back up those hundreds of apps i've acquired over the years... (you live and learn):rolleyes:

    Any help on this would be greatly appreciated

    many, many, many thanks in advance

    Oh so BTW this is how i did it in the end.

    I made a bootable pen drive of os x like this

    I then booted into it using this code

    and then i recovered the files using

    and then repartitioned and reinstalled OS X

    I am now sitting copying my intact (as far as i can see) files back into my lovely OS X.

    Many thanks for all your help with this.

    All the best
