Sometimes things break—it’s Linux life! 💻 Maybe your Manjaro installation isn’t booting correctly after an update or some system tweaks. Don’t panic! You can easily fix boot-related issues using your Manjaro Live USB stick.
Here’s how you can update your GRUB bootloader and regenerate your initramfs directly from a Manjaro Live USB. Let’s dive in! 🌊
🔧 Step 1: Boot into the Manjaro Live USB & Mount your System
Boot your computer with a Manjaro USB stick. Open a terminal and identify your root partition using:
sudo fdisk -l
Let’s say your root partition is /dev/sda2, then mount it:
sudo mount /dev/sda2 /mnt
If you have separate boot or EFI partitions, mount them too:
- For a separate /boot partition:
sudo mount /dev/sda1 /mnt/boot
- For an EFI partition:
sudo mount /dev/sdaX /mnt/boot/efi
(Replace /dev/sdaX with your actual EFI partition.)
🛠️ Step 2: Enter your Installed System with manjaro-chroot
Manjaro makes this super easy:
sudo manjaro-chroot /mnt
Now you’re working inside your actual system environment! 🚪
⚙️ Step 3: Update GRUB Bootloader
Run these commands based on your boot type:
- For BIOS/Legacy boot:
grub-install /dev/sda
update-grub
- For EFI boot:
grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=manjaro --recheck
update-grub
🔄 Step 4: Regenerate your Initramfs
Now regenerate initramfs images:
mkinitcpio -P
🎉 Step 5: Finish & Restart!
Exit the chroot environment:
exit
Unmount your partitions:
sudo umount -R /mnt
And reboot your system:
sudo reboot
That’s it! 🎯 Your Manjaro system should now boot up smoothly.
