I have a 1TB external drive with three partitions:
- FAT32 for extra storage (~500GB)
- Ubuntu (~499GB)
- Linux swap space (~1GB)
I want to boot to rEFind and then to Ubuntu from any Mac; preferably without destroying my Ubuntu install. I would like to split the FAT32 partition into two partitions:
- FAT32 space (500GB minus a few megabytes)
- bootable partition for rEFind (the aforementioned megabytes)
How can I do this, for free, on OS X; preferably from Terminal or Disk Utility? Would making the extra storage partition bootable work?
