From this video you will learn how to update Arch Linux bootloader to dualboot it with another Linux system.
In the video How to Install Linux Mint without a Bootloader you have learned how to install Linux Mint as a second OS along with Arch Linux • How to Install Linux M... This video is a continuation of that video
1. Mount the partition with the new system.
- List the partitions of your system:
lsblk
- Mount it:
sudo mound /dev/sdXx /mnt
2. Install OS prober:
sudo pacman -S os-prober
3. Update GRUB:
sudo grub-mkconfig -o /boot/grub/grub.cfg
You should see that GRUB has found your second Linux system.
When your GRUB is updated, reboot your Arch Linux and try to boot into the second system.
If you configured your Arch Linux to skip GRUB menu and boot as fast as possible, as I showed it in my video “10 Things to do first in Arch Linux”,
You need to press ESC or SHIFT key during the boot to enter the GRUB menu.
If you have not touched your GRUB, you should see this GRUB menu automatically.
And as you can see here, there is a choice to boot either Arch Linux or Linux Mint, which is my second system in this case.
I hope this tip was helpful. I would appreciate if you like and share this video.
