Can't reboot 20.04 after update

[brewersmurf2]

Hello all,

I am in a bit of a pickle...I updated my Ubuntu 20.04, and now I can't reboot...
I tried booting from previous kernels, but nothing. I can get up to the log-in sometimes, but usually get stuck at the black Ubuntu page.
Either way I can't log in. After a while, this line keeps scrolling down my screen "failed to start resolvconf-pull-resolved.service"

I can't reinstall, I need to fix. Can anybody help?

Thank you in advance!

Also, I have dual boot with windows, and windows won't boot either? 🤷

What brand/model system?
What video card/chip?
You do have good backups for both Ubuntu & Windows.

Lets see details, use ppa version with your live installer (2nd option) or any working install, not older Boot-Repair ISO:
Please copy & paste the pastebin link to the Boot-info summary report ( do not post report), do not run the auto fix till reviewed.
