Restore Manjaro grub boot list

If a new Linux is installed in multi-boot after Manjaro, the latter will appear in the new boot list but it will not be bootable.

A solution is to restore and use Manjaro's boot list.

At that other linux grub menu, go into its grub prompt (grub>) by pressing 'c'
At its grub prompt,

grub> search.file /boot/intel-ucode.img root
grub> configfile /boot/grub/grub.cfg
Manjaro grub menu will then appear, enter at the first (top) entry and we will boot into Manjaro.

When booted into Manjaro, at terminal,

sudo grub-install /dev/sda
sudo update-grub
After restart the Manjaro boot list will be accessible directly.
