I was trying to create a triple boot (Ubuntu, OS X and Windows), so I used VirtualBox to install Windows 8 (Consumer Preview) to a real (FAT at the time) partition, so it wouldn't have access to my full drive and overwrite my GRUB MBR.
So now my two partitions ('system' partition, about 300MB, containing recovery stuff?, and Windows partition, with the Windows files etc.) are recognized in GPT and MBR as one partition.
Is there any way I can fix my GPT and MBR (which hybrid, so I can boot both OS X and Ubuntu), so I can somehow split the partitions so I can use GRUB to boot Windows 8?
There is currently Mac OS X Lion, Ubuntu 11.10 and rEFIt installed.
