timeshift retrograde issue on dual boot system (grub)
Posted: Mon Aug 26, 2019 1:23 pm
Hello,
Had to downgrade from LMcinnamon 19.2 back to 19.1 due to cinnamon crashes (I found an rsync image after all) using timeshift from a 19.2 live USB in fallback mode (cinnamon crashes with that also -boo). However then I couldn't boot. The grub menu still showed the various 19.2 options without 19.1 as before downgrade and none of those would work of course. I believe this is owing to having a multi-boot system with Manjaro KDE being the last to be quite recently added which therefore likely owns the boot sector. I had to boot into Manjaro (very nice OS) and updated grub from there which then allowed me to see and boot LM19.1 (with all 19.2 gone)
1. Is there a way to configure timeshift while restoring so that doesn't happen?
2. So how do I re-own the boot sector so I can update grub from LM19.1? I've done it before elsewhere but I forget
Thanks!
Disk info follows, current LM19.1 is on sda5
