Using GRUB2 with a custom OS

[James Read]

Hi,

I'm starting to develop my own OS and instead of writing my own bootloader
wanted to use GRUB2 as a quick fix. I have read most of
https://www.gnu.org/software/grub/manual/grub/grub.html but have been
unable to figure out how to make a bootable USB with my custom kernel file
detected and booted.

Can anyone give me some pointers as to the basic procedure I need to follow?

thanks,
James Read
