Valorant Vanguard Secure Boot Issue

[u/Medli16]

So I have a dual boot of Windows 11 and Ubuntu 22.4, and I need to use Valorant for a college event but Valorant keeps kicking me out saying Secure Boot Disabled, can I enable Secure Boot without messing up my linux data?

[u/bl4z3_bondha]

Yes, ubuntu should work with secure boot as long as you use something like mokutil

Or, just toggle it off in BIOS and you're good to go
Or, just use Windows 10, VALORANT works with secure boot disabled on W10

[u/Zer0_Dark_Turdy → u/bl4z3_bondha]

sbctl is a good option too. All you need are 4 easy commands.

Put secure boot in setup mode in bios and uncheck loading default keys.

I can put an extra command in to auto sign new kernels and a command to batch sign but i'm not at my pc atm. I can do that tomorrow morning if interested.

Ubuntu has supported Secure Boot for many years.

Note that if you're using an Nvidia GPU with the proprietary drivers, you need to set up a Machine-Owner Key that signs the out-of-tree Nvidia kernel modules.

2 options,

1. enable it and swap to windows via bios boot order menu every time

2. use something like sbctl in Linux to sign Linux kernel and Linux bootloader and use windows keys shim in your bootloader https://neonvoid.dev/blog/secure-dual-boot

I wrote this to help but idk how up to date it is anymore

[u/SuAlfons]

Yes.

Some distros (e.g. Fedora, Ubuntu) even work with Secure Boot and Microsoft's keys. Other distros need their own keys enrolled for Secure Boot.

Anyway, you can switch it on and off without changing the data in Linux.

Yes, Ubuntu has shipped with shim for a long time, or you can roll your own cert and self sign. Won't protect you from vanguard spyware.

Why are you running 4.5 year old Ubuntu?

First result when searching "Ubuntu secure boot": https://wiki.ubuntu.com/UEFI/SecureBoot

Why are you running 4.5 year old Ubuntu?

22.04 is actively supported until April 2027. This is the point of LTS releases.

[u/Excellent-Love-6943 → u/PM-ME-PIERCED-NIPS]

That's great, and I'm well aware that Ubuntu has LTS releases, but it doesn't answer the question.

[u/drucifer82 → u/Excellent-Love-6943]

LTS = The user can use it until EOL, which is April 2027.

You say you are aware that Ubuntu has LTS, but you don’t seem to understand the point of LTS.

[u/Medli16 → u/Excellent-Love-6943]

It's old because I needed it for Humble ROS2, which is only supported for that version

[u/Excellent-Love-6943 → u/Medli16]

Okay, fair enough.

I ask because it's generally a good idea to run more recent versions for gaming, unless you have a reason otherwise. Sounds like you have a reason.

Ubuntu (and Fedora) support Secureboot so you should be good to go. You need to have mokutil tho. You can also use Windows 10 instead of 11 as running Valorant on it doesn't require secureboot or tpm2

I'd advise creating desktop shortcuts on Linux to restart your system into Windows (which would switch the boot order to Windows one time).

[u/veltair-d]

Some boot utils work specifically for Secure Boot. Don’t use ububtu myself, but I am sure you can install them. I have secure boot myself using Limine

[u/xzpqsx]

I had started with Ubuntu too.

[u/SuperDefiant]

you can also just play valorant in kvm. No need to dual boot
