I wanted to replace Mac OS X with Ubuntu completely so I put the Ubuntu
.img on a USB drive and ran it and chose the
option in Ubuntu's install menu. I realize this was a stupid way of going about trying to achieve this.
When I try to boot it says:
missing operating system.
I am currently typing this from Ubuntu via the:
feature. According to GParted I have 3 current partitions:
The properties for each of those partitions indicate that only the
linux-swap partition is "active" while the others remain "unmounted". I believe it is
ext4 that holds the Ubuntu installation because GParted indicates that it has something installed on it, it is the largest partition and the other partitions have nothing on them.
If there is anything I can run in terminal to give you more helpful information, please let me know.
I have tried making a new partition table and then reinstalling ubuntu, but when that happens it still does not show anything as bootable and I will get the white screen but then, next, instead of getting a black screen that tells me there is no operating system, I get a flashing folder icon with an "x" in it.
