I want to add something here in case it helps. I had emailed PLUG when I had an issue with my computer as well. It's an old MacBook. I ended up going with this solution after doing some research and experimentation:
1. I created a bootable thumb drive with an Ubuntu on it. 2. I accessed the grub menu by pressing the 'alt/option' key during startup. 3. I selected 'Ubuntu Advanced options'. 4. I pressed 'e' to make edits. But instead of making edits, I pressed 'F2' to get the grub terminal. 5. On the terminal I entered these 3 lines: (1) set root=(hd1), (2) chainloader +1, and (3) boot. By following these steps I was able to reinstall Ubuntu from the thumbdrive. Note: I did not salvage any files with this process. I just wanted to completely wipe all files and reinstall Ubuntu.
