GRUB Boot Repair - Ubuntu Nvidia driver issues

Ubuntu 24.04 crashed on me after an apt upgrade. Immediate documentation was out of date and had to set Google to a custom search range from 2022 - 30 June 2025 to find the correct PPA repository.

It is:

http://ppa.launchpadcontent.net/yannubuntu/boot-repair/ubuntu/

Boot from a USB Ubuntu installer image and access Terminal (Ctrl-Alt-T)...

add-apt-repository http://ppa.launchpadcontent.net/yannubuntu/boot-repair/ubuntu/
apt update
apt install boot-repair
boot-repair

Nvidia driver issue

What we need to do is get rid of the splash screen to see the actual boot messages. This will give us clues about why it's hanging.

Here's how to do it:

Reboot your computer (without the USB).
When the GRUB menu appears (the black screen with "Ubuntu", "Advanced options for Ubuntu", etc.):
- Do NOT press Enter immediately.
- Highlight the "Ubuntu" entry.
- Press the e key (for edit). This will open a text editor with the GRUB boot parameters.
Edit the GRUB parameters:
- You'll see lines of text. Look for the line that starts with linux or linuxefi.
- On that linux line, find the words quiet splash.
- Delete quiet and delete splash.
- You can optionally add nomodeset after ro (so it looks like ro nomodeset). This is a common workaround for graphics driver issues during boot.
  - So, a line that might look like: linux /boot/vmlinuz-... root=UUID=... ro quiet splash
  - Will become something like: linux /boot/vmlinuz-... root=UUID=... ro nomodeset
Boot with the modified parameters:
- After making the changes, press F10 or Ctrl + X (the key to boot with the modified parameters should be indicated at the bottom of the screen).
