I know there are lots of questions re this, but none solve my exact issue.

I accidentally gave a usermod -G instead of -a -G, and so have been removed from sudoers. I am using BIOS, so most of the threads talking about holding shift to get into recovery mode don't work. ESC brings me to a grub command line, but cannot get anything useful out of that. The closest similar question I found (I can't find it again) had the same issue, but his was resolved by typing normal and then it worked. When I type normal, all I get is that it reboots but then ESC no longer works to even get me into the GRUB menu until the next time I reboot.

Ubuntu 20.
TIA

Edit: Despite this being marked as a dup, it is VERY CLEARLY NOT because I reference all of the normal directions, and explain how it's not working. Not only that, but I did end up resolving it, and it goes against all of the documentation, thereby making it novel, and likely useful for others. Typical Stack

    Does this answer your question? How can I start Ubuntu in Safe Mode? If not, then i suppose you will be re-installing.

  • It didn't quite, because that article, along with the others I saw say to repeatedly press ESC, and that was wrong, at least in my case. I pressed it exactly one time, and boom, brought me to the recovery screen I needed. Thanks for the help

    According to this answer: With UEFI press (perhaps several times) the Esc key to get to the GNU GRUB menu screen. This was one of the answers to "How to start Ubuntu in Console mode" even though danny2327 claimed Despite this being marked as a dup, it is VERY CLEARLY NOT.

I resolved it. All of the articles I saw say to repeatedly press ESC, and that was wrong, at least in my case. I pressed it exactly one time, and waited a few seconds, and that brought me to the recovery screen I needed where I could resolve the other issues.
