Do you need GRUB to dual boot?

The UEFI firmware (“BIOS”) can load the kernel, and the kernel can set itself up in memory and start running. The firmware also contains a boot manager, but you can install an alternative simple boot manager like systemd-boot. In short: there is simply no need for GRUB on a modern system.

Does GRUB need its own partition?

It is very useful to have /boot as its own partition, since then GRUB for the entire disk can be managed from there. What does it mean: The GRUB on MBR can only load one GRUB (the rest of it) from disk. That specific GRUB (the rest of it) on disk must be configured to find all OSes on the machine.

Stage 1 consists of 512 bytes and its only task is to load the second stage of the boot loader. Subsequently, stage 2 is loaded. This stage contains the main part of the boot loader.

Where is Grub in the bootloader stage 1?

Stage 1 is the piece of GRUB that resides in the MBR or the boot sector of another partition or drive. Since the main portion of GRUB is too large to fit into the 512 bytes of a boot sector, Stage 1 is used to transfer control to the next stage, either Stage 1.5 or Stage 2.

Do you need to install boot manager for Grub?

Even before the system is booted, GRUB can access file systems of supported BIOS disk devices (floppy disks or hard disks, CD drives and DVD drives detected by the BIOS). Therefore, changes to the GRUB configuration file ( menu.lst) do not require a new installation of the boot manager.
