I had the latest version of Ubuntu on my hard drive and deleted windows 8 with gpart. I noticed a partition called boot efi and it was fat32 so I assumed it was another partition associated with windows and deleted it.
Then, I got a BIOS error about not having an OS, so I installed an old version of Ubuntu. Now it loads right away into the old version I just installed but I can't get it to load my new Ubuntu version which is the one I had alongside windows 8. How do I make an efi file to load the one that has all my work on it?
There's an efi file for this new install of an old version of Ubuntu so it loads into that right away. 438.91GB is my main Ubuntu version I was using before all this happened. See pic:
