I have a Macbook Pro8.1 and I would very much like to have a dual boot system on it.
I prefer the USB Media installation method, as it's the only option I have at the moment.
I've followed the instructions here:
These are the terminal commands that I have used :
hdiutil convert -format UDRW -o ~/Desktop/ubuntu-12.10-desktop-amd64+mac.img ~/Desktop/ubuntu-12.10-desktop-amd64+mac.iso sudo dd if=/Users/sary/Desktop/ubuntu-12.10-desktop-amd64+mac.img of=/dev/rdisk2 bs=1m
This is my setup :
- installed Refind
Formatted the USB in " Disk Utility " :
Selected '1 Partition' and 'MacOS Extended (Journaled)'.
Partitioned the USB as :
GUID Partition Table (GPT)
This is the ISO img that I used :
Ubuntu 12.10 amd64+mac version " ubuntu-12.10-desktop-amd64+mac.img " .
After a shutdown, Refind shows up and it's working properly.
But, when I select the USB Media drive it leads to a black screen that reads "Non-system disk " .
I would like to know what exactly I am doing wrong, or missing, here?
Should the USB format be in "Mac OS Extended (Jounrnaled)" , "MS-DOS (FAT)" or "ExFat" ?
Should it have 1 or 2 partition Layout?
If it must be formatted as Mac OS Extended (Journaled), does it mean the partition scheme should be set to "GPT" or "MBR" to have an Ubuntu bootable USB drive ?
