Restore the /boot partition

Yea how do I do that

you still need to clean your disk, since its full:
clear your journal:
sudo journalctl --rotate
sudo journalctl -m --vacuum-time=1s
clear pacmans cache:
sudo pacman -Scc
then search here on forum or on manajro wiki how to reinstall bootloader
youll do it from manjaro usb and from chroot with this command:
sudo manjaro-chroot -a
and then follow this link

So do I format and remake the /boot and /boot/efi before this?

first clean your disk… oh i see you have two bootloaders one for win one for manjaro?

Cannot really ditch windows due to games and the Ms office suite.

i just wanted to know if you have 2 bootloaders … so dont touch the windows boot, only the manjaro one …

So I am safe to format boot and boot/efi
Because the grub bootloader I am very sure it is on a separate drive

if they are not related to windows then yes… i never restored the grub loader so i dont know what exactly you have to do, so the wiki link and also posts here on forum will be helpfull to you

Some pain later the new boot entry in the boot selector boots into nothingness and restarts

did you followed the wiki and checked on forum how to restore grub? because i have no experiences with it … maybe creating a new topic with failed restore of grub, and detailing what exactly you did …

Guess I will be stuck with windows for a while. I was planning to switch to Arch soon so this might as well be the push I needed. But for reasons I will not be using the install script.

all right, but dont again let your disk gets full

I’ll make it 512 MiB now
Each for /boot and /boot/efi
Because I do not have the vaguest idea, just to be sure.

Luckily the / partition is intact I can backup anything that matters.

I have a 300MB partition for /boot/efi and a 1GB partition for /boot.
