GNU Grub when booting

[GS84700]

Hi everyone,

Just a couple days ago, I signed in the forum to see how to update firefox on linux mint (yes, I'm a newbie). As it turned out, I had no updated mint-upgrade-info. I did that and a whole bunch of updates, including firefox became available and I downloaded all of them. For details, if that is important for the topic at hand, here's the link to that thread:
viewtopic.php?f=47&t=269918&p=1472857#p1472857

So... After that, I used my laptop without shutting it down.
Now I did shut it down, and when I turned back up, instead of booting, I got the following message (in French since I'm French, but it's translated here)

GNU GRUB version 2.02~beta2-36ubuntu3.14+linuxmint1
Minimal BASH-like line editing is supported. For the first word, TAB lists possible command completions. Anywhere else TAB lists possible device or file completions.

grub>

Only linux mint is installed on my computer.

Once again I'm no tech buff, and I choose to migrate from apple to linuxmint because mint was supposed to be very low to zero maintenance. I know, dispointing, we all have different gifts.

Thanks for any input/advice on how to solve the issue

I might add that I'm currently reading the grub manual, to no avail, and that the default keyboard has been changed from azerty to qwerty, which makes it a pain to work with.

Looks like one or more of the Level 4 & 5 updates has borked the system = a reinstall of LM is likely needed. ...

That will teach me a lesson to download without paying attention Live and learn...
So there is just no way to restart computer with setup previous to the upgrade that cause the system to fail?
And does that mean I've lost all my data on my pc?

After quite some research I have found that if I press shift during loading that would make the grub menu appear, from which I could choose the old kernel since the new one is not working.
Problem is, I've tried shift, right shift, space, escape, etc. I can't access the grub menu

Can someone please tell me how to access grub menu (the version is 2.02 beta 2
thanks a lot

Re keyboard changing itself to qwerty; Click on menu, click on preferences when it opens, about 3/4 way down you should find <keyboard>click on that ,go to layouts click on add (or+)then either by language or country scroll down until you find your desired layout click on add. in the next window there should be a place to test your layout; if it works lucky you: I had to restart 5 times with the DVD version of Mint 18,3 to get a German Layout that stayed there. Needless to say I am not impressed with Mint 18,3
I hope you have better Luck.Liam

I've figured it out!!!!!!!
So here is what I've done, following in great part this page I've found on the internet :
https://www.linux.com/learn/how-rescue- ... ub-2-linux

grub> set root=(hd0,1)
grub> linux /vmlinuz-4.10.0-38-generic root=/dev/sda1
grub> initrd /initrd.img-4.10.0-38-generic
grub> boot

And I've hurried to erase the kernel that cause all that mess
Need to reboot and make sure it works!

So yes it works!

I hope this will help any users not being able to access grub menu.
