Hello - I did an upgrade to Mint Vanessa and after the upgrade at reboot I get error
error: '/boot/vmlinuz-5.4.0-146-generic' not found
error" you need load the kernel first

This is a multiboot system and I am able to boot to MX Linux

Any help is appreciated (limited knowledge here)

open a terminal in mxlinux run reboot see if that fixes it. If not will need more information about the partitions/uuids of the systems.

Ok - I ran it and thought maybe it was going to be fixed but...same think on reboot.

$ sudo update-grub

At the boot menu, highlight mint press e for edit change /boot/vmlinuz-5.4.0-146-generic on the linux line to /boot/vmlinuz and the initrd line to /boot/initrd.img
ctrl-x to boot.
If that doesn’t work change to /vmliuz and /initrd.img
If it boots open a terminal and run "sudo update-grub

OK when I - highlight mint press e for edit change /boot/vmlinuz-5.4.0-146-generic on the linux line to /boot/vmlinuz and the initrd line to /boot/initrd.img
ctrl-x to boot.
This worked except.... when i made the changes and hit cntrl-x it went back to the boot option screen and got same error.
When i made the changes and hit F10 it went ahead and booted into Mint but when i ran "sudo update-grub" i get the following...
mint@mint-System-Product-Name:~$ sudo update-grub
Sourcing file `/etc/default/grub'
Sourcing file `/etc/default/grub.d/50_linuxmint.cfg'
Sourcing file `/etc/default/grub.d/init-select.cfg'

/etc/grub.d/bin/grubcfg_proxy: error while loading shared libraries: libcrypto.so.1.1: cannot open shared object file: No such file or directory
mint@mint-System-Product-Name:~$
Then when i reboot and select Mint the original error comes up
So... if hit "e" on Mint during boot and make the changes and hit F10 it will boot into Mint but it doesnt seem to save the changes nor does "sudo update-grub" seem to correct the issue.
It is a start though as I can at least get Mint to run.

try running
sudo apt update
sudo apt upgrade

OK - ran those and error still pops up at boot.
Loads fine when i hit "e" to edit and remove the text as suggested.

This is the problem:
a little googling I came across on how to fix:

To keep from having to edit the grub menu each time a temporary fix is to edit /boot/grub/grub.cg and make the /boot/vmlinuz and /boot/initrd.img edits to the first grub mint entry.

Ok.... per the link you provided I....
Download the .deb file from the link below to your Downloads folder.
http://security.debian.org/debian-se...b9u6_amd64.deb

Then per the thread ran sudo update-grub

mint@mint-System-Product-Name:~$ sudo update-grub

Now Im going to reboot and see what happens!

Hmmm....well that didnt work. I still have to edit the two lines.
(perhaps I missed the actual fix in the link?)

post the contents of /etc/apt/sources.list

Maybe...this?

root@mint-System-Product-Name:/etc# cat /etc/apt/sources.list
# deb cdrom:[Linux Mint 20.1 _Ulyssa_ - Release amd64 20210103]/ focal contrib main
# This system was installed using small removable media
# (e.g. netinst, live or single CD). The matching "deb cdrom"
# entries were disabled at the end of the installation process.
# For information about how to configure apt package sources,
# see the sources.list(5) manual.
root@mint-System-Product-Name:/etc#

what about the contents of /etc/apt/sources.list.d/official-package-repositories.list

That's strange, there was no errors with update-grub and the file in sources.list.d looks correct. run
