So I screwed up my dual-boot ubuntu and MacOS on my Macbook, when and there are no boot partitions so I'm currently trying Ubuntu from a USB
I can see the original MacOS partition in GParted, it's in my /dev/sda disk but it's inbetween two unallocated partitions; Unallocated (200MB) - /dev/sda2 (83GB) - Unallocated (29.7 GB)
I right clicked my MacOS and selected the boot flag, but it won't recognise it on boot.
How do I tell it to use the /dev/sda2 partition as the boot partition? :S
