Help to delete linux partitions

[JohnFante]

I have a Mac MINI PPC with OSX 10.04

How do I delete my Linux partitions within Max OSX?

I have tried the Disk Utility but can't get it to work. There is no minus when I mark the linux paritions and when I try to erase everything I get an error saying there is no acitvations point.

I can not use gparted since I can't boot from the live cd (my pc keyboard is not recognized. At the time I installed I borrowed a MC keyboard).

Thank you in advance.

Did you install Ubuntu on the same HD where also MacOSX is running?
I don't remember very well, but you can't do it in Tiger while MacOSX is running.
Therefore you should start from the MacOSX Installer and delete the Partition (with the Apple Disk Utility).

BACK UP ALL YOUR IMPORTANT DATA ON MACOSX!
I'm afraid that you will loose them, and you have to reinstall MacOSX.
