I tried to install elementary os from a live USB with unetbootin on Ubuntu, following the instructions on the EOS site. I chose the option to install alongside Ubuntu and created a new 200GB elementary OS partition.
The installer said that everything had worked, and to restart my computer, but now I can only boot into ubuntu, the new partiton appearing as a 200GB external drive.
How can I fix this? I have tried changing the boot order in the startup menu but there is only one UEFI partition to boot from called "ubuntu", and no elementary OS partition, even though it exists on my system.
