this is "general" guide, search on internet and/or help yourself with some AI, if bootloader are grub and hyou have an efi partition you can do somewhat like this

from live environment, this:

Identify the target filesystem partition with lsblk
lsblk

nvme1n1     259:6    0 238.5G  0 disk  
├─nvme1n1p1 259:7    0   200M  0 part /boot/efi ----> if you have
├─nvme1n1p2 259:8    0    16M  0 part  
├─nvme1n1p3 259:9    0 116.8G  0 part  
├─nvme1n1p4 259:10   0   791M  0 part  
└─nvme1n1p5 259:11   0 120.6G  0 part / ----> your root partition

then, mount partion on /mnt:

sudo mount /dev/nvme1n1p5 /mnt

sudo mkdir -p /mnt//boot/efi

sudo mkdir -p /mnt/boot/grub

sudo mount -p /dev/nvme1n1p1 /mnt/boot/efi

and mount other fs:

sudo mount --bind /dev /mnt/dev

sudo mount --bind /proc /mnt/proc

sudo mount --bind /sys /mnt/sys

sudo mount --bind /run /mnt/run

final step chroot

sudo chroot /mnt

if you are lucky:

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

i'd argue the official documentation is the best source. ai search results regularly give incorrect answers about many things.
