Limine is cool, but it need the uuid and it can not auto find out where is the easyos file.
Grub2 can search all disk partition to boot a linux, that is very simple and convenient.
Can we use a grub2 menu to boot easyos?
I think this way is better, because we need not know which partition contain the file, we only need know the file name, for example:
if search --file --set /EFI/Microsoft/Boot/bootmgfw.efi ; then
chainloader /EFI/Microsoft/Boot/bootmgfw.efi
