Accidentally "repaired GRUB" with boot-repair, how to undo the repair/reinstall backup?

io flag

I accidentally clicked "repair GRUB", now my keyboard doesn't work until after the boot sequence.

I'm fairly certain there was a backup made (didn't change any of the settings, and new files were created), but I can't find the right instructions for what I need to do.

How do I restore the backup made by boot-repair?

It's not a direct solution to your problem, but if your computer has still USB 2.0 ports, attach your keyboard to a USB 2.0 port, instead to a USB >= 3.0 port. This should enable your keyboard again. If that also doesn't work, your BIOS has probably disabled `legacy USB support`, try to enable it.

I do not believe there is a backup. It just updates. What updates did it do? Default is often just a `sudo update-grub` which just updates grub menu. It may offer to do a full grub reinstall & update to the newest kernel which may update other software. Keyboard issues often are in UEFI/BIOS settings. Grub does not have keyboard driver and uses the UEFI/BIOS. If Boot-Repair's updates also triggered a UEFI firmware update, UEFI then resets to defaults. Recheck UEFI settings & make sure USB keyboard & mouse are enabled or full USB support is on.

@oldfred Something likely updated itself, I was able to use the keyboard this morning strangely enough. Thanks for the knowledge nonetheless! Cheers.

@paladin Oh, yes! I have both versions on this case. Thankfully it seemed to fix it self somehow, anyway. Thanks for sharing that trick!

Thanks for the knowledge everyone. It just fixed itself overnight, or on the fifth/sixth reboot.

I didn't do anything except give up, and go to sleep. I suppose this a good answer to some problems!

Cheers.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
