I have both Ubuntu and Win 10 installed, I'm currently using Win 10.
When I was running Ubuntu, I got an update pop-up, I downloaded all the updates and started the installation, but it got stuck at configuring grub-pc (grey screen), so I just ignored it, and continued using Ubuntu normally. Now, when I try to launch Ubuntu, I get this error:
kernel panic-not syncing: VFS: unable to mount root fs on
unknown block(0,0)
I assume the update broke grub, how do I fix this?
