This is my first question, so maybe I'm gonna do something wrong. I ask pardon in advance.
I've performed a proper dual boot installation of Ubuntu 18.04 alongside with Win10 (which was already installed on my PC) and it worked great for a couple of months. After I installed the latest Win10 update (to version 1909), Ubuntu can't even boot anymore.
Maybe I need to update the Grub, but I don't know how to do since I can't start Ubuntu.
Here is a pic of what I see on my monitor while Ubuntu is trying to boot:
Please, I really need to solve the problem asap, 'cause I need both of them.
