I'm trying to install Ubuntu on my computer, but I've run into an issue. The installation requires that I disable Secure Boot, and while Ubuntu works fine once it's installed without Secure Boot, I can't boot into Ubuntu when I turn it back on. I thought that Ubuntu was compatible with Secure Boot. Am I missing something?

Ubuntu does support Secure Boot. During the installation, you should select the option to install third-party drivers, which typically includes enabling Secure Boot support. If it's been a while since you last did this, there are guides that can help, like the one I found about enrolling the MOK key after installation. You might want to check that out!
You usually can install Ubuntu with Secure Boot enabled. Did your installer really say you had to disable it? That's kind of strange!
Did you use Ventoy to start Ubuntu? Because Ventoy doesn’t support booting with Secure Boot. If you used Rufus in DD mode or Balena Etcher, those options typically create a Secure Boot compatible USB. Just a thought!
I tried using Rufus in DD mode, but it still doesn't work for me.
You can actually set Ventoy to support Secure Boot while creating the Ventoy drive, so it might be worth looking into that option.

Is that possible to do after installation? Sounds like a good workaround.
