When I get to the rEFIt menu it only shows Mac OS X. In the partition inspector it shows this:
*** Report for internal hard disk ***

Current GPT partition table:

It appears as though there is no MBR entry for the Ubuntu partition. Does this have something to do with it? Can I add the Ubuntu partition and then flag it as bootable with fdisk?

Edit: it appears as though the MBR supports only 4 primary partitions. Should I change the Linux swap partition in the MBR to the main Ubuntu partition and then flag it?
