+1 for the relative simplicity of rEFInd. I've only used it on a MacBook Pro, some years ago now, but it worked like a champ to dual boot Gentoo: https://wiki.gentoo.org/wiki/Refind GRUB is rather bloated, because it tries to be all things to all men. However, you don't have to use GRUB's mkconfig command to automatically generate a boot menu. You still can author manually your very own grub.cfg as described further down this page: https://www.gnu.org/software/grub/manual/grub/grub.html#Booting Then you'll configure whatever GRUB_CMDLINE_LINUX kernel options you need. There's also syslinux, which I have only used once. It worked. Not sure if it meets your needs, but I mention it for completeness: https://wiki.gentoo.org/wiki/Syslinux
