Public bug reported: I had another OS installed, and have had 17.10 installed for a number of years without issues - which was an upgrade from maybe 16.04. I have now tried 3 times to install 20.04 as a clean install over 17.10, and both those attempts resulted in the system rebooting into grub rescue (but no clues as to how to progress from there). I then tried a clean install over my disk, and having selected the entire disk, the installer crashed. The USB stick I am using worked fine when used the other day with a Thinkpad, which is why I was installing my work laptop today. This is the only installation issue I have had, and I have installed Ubuntu on at least 7 PCs and been running it since c. 2008 - or earlier.
