This is an awesome boot loader. It can boot pretty much anything.
With the impending Secure Boot and TPM forced requirement for Windows 11, for convenience, this means you need to comply with other boot loaders.
The good news is there is no need to faff around with Shim and MOK for motherboards that allow you to manage your secure boot keys. Both of which are chained boot tools to make secure boot work. These manual instructions ONLY work for these types of boards. Commonly DIY or SI. For other motherboards (OEM computers), you will need to read the current documentation for that. Though given the nature of OEM computers (can't manage keys manually), this may prove difficult and/or require a Linux install.
In this example for these instructions, I am using my ASUS ROG Crosshair VII Hero. An AMD X470. In the case of ASUS Intel motherboards, like a Z490, the steps are the same.
