    rEFIt does not see Ubuntu partition

    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:
    # Start LBA End LBA Type
    1 40 409639 EFI System (FAT)
    2 409640 725503591 Mac OS X HFS+
    3 725503592 726773127 Mac OS X Boot
    4 726773128 742773128 Linux Swap
    5 742773129 742777035 GRUB2 BIOS Boot
    6 742777036 976773118 Basic Data

    Current MBR partition table:
    # A Start LBA End LBA Type

    2 409640 725503591 af Mac OS X HFS+

    4 726773128 742773128 82 Linux swap / Solaris

    MBR contents:
    Boot Code: None

    Partition at LBA 40:

    Listed in MBR as partition 4, type 82 Linux swap / Solaris

    Partition at LBA 742773129:
    Boot Code: None

    Listed in GPT as partition 5, type GRUB2 BIOS Boot

    Partition at LBA 742777036:
    Boot Code: None
    File System: ext4
    Listed in GPT as partition 6, type Basic Data

    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?
