OK well all of this is different if  you go UEFI. Pretty much nothing I've said applies to UEFI and that includes there being no such thing as installing boot loaders to partitions. There are no MBRs or VBRs. Instead there's a UEFI boot manager, and almost invariably you'll have to get familiar with that in order to choose which OS you want to boot, because a unified grub menu that shows all linux distros just isn't working reliably for everyone yet. You could even choose to not deal with GRUB2 on UEFI for that matter, you could use gummiboot or rEFInd, both of which are smarter about multibooting linux distros. However, no autogeneration of configuration file, so you have to learn some scripting. Nothing approaching what's required to know about GRUB however which is god awful complicated for just being a bootloader.
