I have installed MorphOS in a dual boot setup on my Mac Mini, following this guide. Quick and unofficial..
I was using the option in section 4 to resize my existing mac partition and create the needed ones for MorphOS.

Everything went very well, and the guide was very easy to follow. (only had a bit trouble before I found that I had to set the no-splash option in order to boot the ubuntu live CD on the mini)

Now its all working, but there is only one annoyance when booting into the Mac. The volume "Boot" gets mounted on the Mac and OSX complains every restart about that:
"The disk "Boot" Boot could not be repaired by this machine. It will be available with limited functionallity. You must backup your files and reformat it as soon as possible"
(probably not exact what it says in english, I have a norwegian setup)

Have anyone else got this message on their dual boot setup?

Now, I could try to backup the files and reformat it in OSX, and copy the files back and hope it will work. But I worry that this might destroy the boot disk for MorphOS?
Or is it some way of making the partition hidden from OSX, or provide it from getting mounted on the Mac side?

Any advice on this matter?

Thanks Andreas :) I'll update the dualboot.pdf with instructions on how to avoid this issue when I have the time.

It's been a few months, so hopefully I'm remembering this right, but I overcame this issue by reformatting from the Mac side, then copying everything back and re-blessing from MorphOS.

Sure, that'd work too, but to do this you need a boot CD or booting MorphOS manually from the OF prompt.
