Issues with Secure Boot Enabled on Dual Boot (Windows 11 + Zorin OS 17)

Hello everyone,

I have a dual boot setup with Windows 11 and Zorin OS 17. When I initially installed both systems, Secure Boot was disabled.

Recently, I had to enable Secure Boot in order to play Battlefield 2042, as the new EA anti-cheat requires it. However, after enabling Secure Boot, I started experiencing issues in Zorin OS — particularly with the Nvidia driver and the network adapter.

More specifically:

  • One of my monitors is not recognized after booting into Zorin.
  • My network connection doesn't work at all.

Is there a way to use Zorin OS with Secure Boot enabled, without running into these issues?
It's quite inconvenient to enter the BIOS and toggle Secure Boot every time I want to switch between Windows and Zorin.

My motherboard is an ASUS TUF Gaming X870-PLUS WIFI.

Any help would be greatly appreciated!

Thanks in advance!

Many on Zorin OS have issues with "Secure Boot" enabled, as its a feature designed for Windows, and doesn't work on Linux. We typically recommend keeping "Secure Boot" disabled for Linux users, as it causes more harm then good.

Also, when you login to Zorin OS, make sure you are running on Zorin OS on Xorg, don't use Wayland. You however are running into issues caused by SB being enabled, thats your prime issue.

Additionally, I believe all game studios who make a game designed around Anti-Cheat, to be evil. They know anti-cheat ruins the Linux experience, and they don't care. EA are also the worst and most evil of game studio's.

I have never turned secure boot on, on any of my linux, but do some research on MOK. I have a feeling it's what will fix your gpu issues.

​MOK, which stands for Machine Owner Key, is a security feature in Linux that works in conjunction with UEFI Secure Boot

Welcome to the Forum!

Is in Windows Fast Start-Up disabled?

And with disabled Secure Boot it has worked, yes?

I don't recall if Fast Start-Up is enabled or not.

And with Secure Boot disabled everything works fine on Zorin.

Could be worth to check that and disable if active.
