I have recently installed iDeneb 10.5.5 and Ubuntu 9.10 on my PC, all on the same disk. At the end of my Ubuntu install, I installed Grub2. I wonder how I can boot in OS X with grub. Do I have to chainload into the Chameleon bootloader or do I boot into Mac OS X, and how do I configure this? Over the last few hours, I did everything I could think of to get this to work and I'm getting desperate.

Thanks for helping out!
