Secure Boot Invalid Signiture Error

Hello
So I installed Fedora while Secure Boot was disabled and then I enabled it but it says invalid signature and wont boot. Any one can help?
If it helps I am dual booting Windows 11 and using SystemD boot as I had PopOS installed before installing Fedora.

I would have expected this to work.

Maybe post a picture of the error message for context?

Install Fedora 39 with systemd-boot and secure-boot ‘enabled’ - #4 by vekruse

that is a bit old. is that still the case?
how would I move from systemd boot to grub2?
grub2 is installed but only windows is showing in menu.
re-installing kernel and then re generating config in Fedora does not work

It is still the case. You can force installing Fedora with sd-boot when using the Network install iso or the Fedora Server version. That does still not support secure booting unless you do some tricky things and knows what you are doing.

Fedora will install with grub2 and the Fedora version of shim. The Fedora version of shim holds the certificate for the Fedora kernels, and any other shime version won’t boot Fedora kernels unless you enroll the Fedora key.
