View Full Version : [ubuntu] issues with installing, and booting a Mac with Ubuntu on an external HD

So, I need some help. I've been trying to install Ubuntu 12.04 LTS on a 2TB external USB HD and then boot my 2010 MacBook Pro from that. My external HD is formatted as a GUID partition table. I was able to install Ubuntu correctly, by connecting it to a VMWare virtual machine, and selecting the USB HD from the install process. I properly partitioned the drive: a swap partition of 8GB, then a 4MB partition for the GRUB and the rest for the main OS partition. I burned reEFIt (as a bootable cd) (http://refit.sourceforge.net/doc/c1s5_burning.html), booted from the CD and the menu sees my external hd. I selected that and I get thrown into my Windows 8 partition. I'm all out of ideas as to why I can't boot from the external HD. Any help would be amazing. Thanks!
