Where do I install GRUB?

[baigel]

I want to dual boot WIndows 10 and Manjaro. I have windows 10 already installed. I wanted to know if should delete the windows boot manager partition and set it to /boot/efi ? Or should I make set the /boot/efi mount point to another partition entirely?

Let Grub take care of that, the installer is smart enough to figure it out for you. Just point the installer to the disk where you have installed Win10 and let it run.

Well, that is not really accurate, but you definitely should NOT delete windows boot partition, the rest depends on if you want to have Windows or Manjaro as default option (which boot loader is going to be written to MBR). If Windows should be the default option than you install Manjaro, and run the following commands in Windows recovery (they do write the to windows bootloader to MBR, which means that boot sequence will go as follows: windows boot loader -> grub -> Manjaro OR windows boot loader -> Windows

bootrec /RebuildBcd

bootrec /fixMbr

bootrec /fixboot

If Manjaro should be the default one, than you just install it and everything should be ready to go. (boot sequence will be: grub -> windows bootloader -> Windows OR grub -> Manjaro)
