    Ubuntu 13.04 on OSX MBP and external drive

    Hi,

    Im trying now for two days and tried everything and I cant boot to Ubuntu on external HD. On OSX Disk Utility I have created new partition on ext. HD and leave it as free space. Then I have downloaded Ubuntu desktop 13.04 and burn it on DVD. I restarted MBP and hold the "c" key to boot from DVD. Everything goes OK. I have installed Ubuntu on this free space partition (I have change it in installation process to ext4 partition type and to / as a mount point, about 250GB partition "/dev/sdb4"). I have also choose Device for boot loader installation" /dev/sdb4, so the same where installation is. I have also created a swap partition (around 10GB). Installation goes fine and everything is OK. Then I have booted to OSX and installed rEFInd which also was successfully. I have rebooted OSX and rEFInd menu appears and also a Linux partition. I have choose it and I get like "No operating system found" and also "There is no bootable device" (something like that). I have tried a lot of things and nothing works.

    What Im doing wrong?

    My MBP is MacBookPro8,2" and have OSX 10.8.4

    Partitions on ext. HD:
    /dev/disk1
    #: TYPE NAME SIZE IDENTIFIER
    0: GUID_partition_scheme *750.2 GB disk1
    1: EFI 209.7 MB disk1s1
    2: Apple_HFS External 1TB 497.4 GB disk1s2
    3: Linux Swap 10.0 GB disk1s3
    4: Microsoft Basic Data 242.4 GB disk1s4
    5: 21686148-6449-6E6F-744E-656564454649 134.2 MB disk1s99

    @LionRock, you posted in the Other OS/Distro Support forum which is for any OS except Ubuntu. I've moved your thread to the Apple Users forum which is for Ubuntu on Apple hardware where it is more likely to be seen by those who can help you. Good luck.

    Please do not PM me about your forum account unless you have been asked to. The correct place to contact an admin about your account is here.

    Hi,

    Did you check in http://ubuntuforums.org/showthread.php?t=1046568 ? There is a part which might help you "I installed, but Ubuntu won't boot / says "no bootable devices" / has a blinking cursor!"

    Also, there are firmware restrictions on certain models that don't allow for booting from devices connected via USB. More specifically, for some models (the MacBook Pro with Retina display, Mid 2011 and newer Macs mini, the Late 2012 iMac and all MacBooks Air) the firmware only allows for booting from external SuperDrives which require matching of other criteria specific to your device. Hope this helps.
