I can no longer boot MX-16.1 on my dual boot system.

grub rescue error: file `/boot/grub/x86_64-efi/normal.mod` not found

Tried to repair grub using MX Tools (USB MX-16). No joy.

I mounted / (/dev/sda4) manually from a terminal window.
/boot/grub/x86_64-efi/normal.mod does indeed exist.

What can I "try" from the grub rescue prompt to get MX-16.1 to boot?
( I would prefer not to reinstall MX from scratch if possible, MX-17 will be out in a few months).

By the way this boot problem occurred immediately after installing Ext2Fsd on the windows system / partition.

Thank you in advance for any advice or suggestions offered ...

looks like you mixed uefi and legacy boot mods. check BIOS settings. Sorry, my bad!!! Misunderstood that to a new install.
Possibly you need to check file system using e2fsck.

Boot into some live CD/USB and mount partition containing grub configs and check partition labels/id's. I'm not sure what's causing the problem but it could be due to a reordering of partition labels. So, check uuid's and id's in general with respect to what is present in the grub.cfg.

Thank you colorpurple21859 for the grub rescue how to link.

I am now able to at least boot my Linux system by entering the following:

set prefix=(hd0,4)/boot/grub
set root=(hd0,4)
insmod normal
normal

which brings me to expected grub boot menu.

I will start a new thread to help me determine why I can not
correctly configure grub.

Thanks to all who posted replies.
