[QUOTE="Sur3Mac, post: 910804, member: 113359"] Ubuntu uses Grub as it's bootloader, OSX uses Darwin. But Ubuntu, on setup wil not see the OSX Boot, so you'll have to manually enter it, and edit Grub. You'll have to boot back into Ubuntu, Open a terminal and type: sudo gedit /boot/grub/menu.lst This is the boot list for OS/Memtest etc. Scroll to the bottom of the grub menu and enter the following under where it says ### END DEBIAN AUTOMAGIC KERNELS LIST title MacOS X rootnoverify (hd0,*) makeactive chainloader +1 Substitute the * for the partition number, in your case it maybe (hd0,1). The sudo command emulates root permissions, so you can log in as any user. If you're having trouble with this, it might be a good idea to just restore your OSX Partition from Time Machine, if of course you have it backed up. Hope this helps;D PS I only just read that you didn't actually install Ubuntu yet, in that case, do a back up restore [/QUOTE]
