I am using grub-mkrescue to create an iso image out of my kernel.
This works fine in an emulator but once I use rufus to burn the iso image to a usb it refuses to boot.
The grub menu comes up fine but gives me "error: symbol 'grub_efi_secure_boot' not found'.
I tried messing around in the bios options for my laptop but I cant find anything that relates to secure boot.

Any help would be appreciated.

I had the exact same error just last night, what a coincidence
What I did was burn the image using Rufus's DD image mode, that fixed the issue for me.

I have the exact same problem. What is Rufus's DD image mode?
PS: okay I found lol many thanks

Wise words... This is going to happen to you over and over again if you're not using a POSIX system for development! A Linux or BSD would have had "dd" and "cdw" at your disposal
