Install the GRUB Bootloader

NOTE

GRUB is a versatile and widely supported bootloader, making it an excellent choice for most systems.

1. Install GRUB to the Boot Partition

Use the following command to install GRUB:

UEFI

grub-install --target=x86_64-efi --efi-directory=/boot --bootloader-id=grub --removable

MBR BIOS (legacy boot)

grub-install --target=i386-pc /dev/sdX

Explanation of Arguments [UEFI]

• --target=x86_64-efi: Specifies the installation for 64-bit EFI systems. Omit this for legacy BIOS installations.
• --efi-directory=/boot: Indicates the directory where GRUB should be installed.
• --bootloader-id=grub: Sets the name of the bootloader as it appears in the BIOS boot menu.
• --removable: Ensures compatibility and prevents boot issues when BIOS settings are changed.

Explanation of Arguments [MBR BIOS (legacy boot)]

• grub-install: Installs the GRUB bootloader.
• --target=i386-pc: Specifies the target for legacy BIOS (MBR) systems.
• /dev/sdX: Replace sdX with your disk (e.g., /dev/sda). This installs GRUB to the disk’s MBR, not a partition.

2. Generate the GRUB Configuration File

TIP

This command creates the configuration file, enabling GRUB to manage and load operating systems.

grub-mkconfig -o /boot/grub/grub.cfg

---

3. Final Steps

You’ve successfully installed GRUB and set up Arch Linux!

• Exit the chroot environment:

  exit

• Unmount the partitions:

  umount -R /mnt

• Reboot your system:

  reboot

NOTE

Remember to remove the installation media (e.g., USB) after rebooting to avoid booting into the installer again.

IMPORTANT

I haven’t mentioned or written anything about installing graphics drivers for NVIDIA or AMD GPUs. You can find information for NVIDIA in these docs, but I strongly recommend checking the official Arch Wiki for installing GPU drivers for both NVIDIA and AMD.

While I could include the documentation here for installing graphics drivers, it may not be the most effective way to properly set up your GPU drivers. Thank you.
