1-Create modified filesystem.squashfs
mksquashfs / /mnt/disk/filesystem.squashfs -comp xz -e /rofs /cdrom /media /proc /sys /mnt
2-Delete filesystem.squashfs from the iso and replace it with the one from step 1
3-boot from the iso file 
4-install Cubic
sudo apt-add-repository ppa:cubic-wizard/release
sudo apt update
sudo apt install cubic
mount squashfs from the iso with the modified filesystem.squashfs to /media/mint/disk/

take the numbers from 

sudo apt install --reinstall linux-headers-5.15.0-41 linux-headers-5.15.0-41-generic linux-image-5.15.0-41-generic

compress custom-root/boot to a tar.gz archive 

sudo rm -rf * inside custom-root

sudo rsync -av -A -X /media/mint/disk/ /media/mint/c83f4a2e-933b-4e2e-8d80-2f7fff081412/custom-root
sudo rm -rf /custom-root/boot

4-in chroot execute 
sudo mkdir proc
sudo mkdir sys
sudo chmod 755 proc sys

extract the compressed file. You will find it in /root/Desktop 
copy the extracted files to custom-root/boot

5-if you are asked what kernel to select. The last entry always has a short name, select it.
