[SOLVED] Trouble with GRUB re-installation

[gold_finger]

In order to avoid troubles with GRUB conflicts I installed each fresh installed distro's GRUB on each one's / and over them all I tried to re-install
Lite's GRUB

If you installed (grub) boot loader for other distros to their respective root partitions, then all you needed to do is boot back into LL afterwards and run this command to add them to LL grub's boot menu:

Code:

sudo update-grub]

Because of modifications made to LL's grub configuration, trying to boot LL from the grub of a different distro ends up being extremely difficult.  Therefore always a good idea to leave LL's grub in charge of booting the machine (which is what you were trying to do).  In your case, you didn't need to try installing LL's grub to each distro's root partition afterwards (if that's what you were doing) and that ended up just causing problems.

Now, to get LL booting again, boot from live LL disk and follow instructions below in a terminal.  Each line below needs to be entered separately and in the order shown.   [Note: anywhere you see "XY" or "X", change that to the correct drive letter ("X") and partition number ("Y") for your LL root partition.]

Code:

sudo mount /dev/sdXY /mnt
for i in /dev /dev/pts /proc /sys; do sudo mount -B $i /mnt$i; done
sudo chroot /mnt
grub-install /dev/sdX
update-grub
exit
for i in /sys /proc /dev/pts /dev; do sudo umount /mnt$i; done
sudo umount /mnt
