This is my first post in this amazing community (but I've been using Linux for 9 yrs now), and I am so excited to see your smiling faces!
I have been running Ubuntu MATE without any problems on this very laptop for a little over a year now. I originally installed 16.04 LTS and then later this year upgraded to 18.04 LTS, without any problems. Everything was working great!
It all started, when I decided to upgrade the HDD in my Lenovo V570 with a SSD. Every-time I boot my computer, I go to GRUB prompt. Even when I manually chose to boot from my SSD. But to my luck, I stumbled upon this post - except in my case, I was not seeing grub rescue prompt, but grub prompt instead.
So now, I always have to run following commands on GRUB prompt, every single time I boot my computer, but at-least I am making some progress! (What progress? A post explaining what was happening before I deleted MBR, and why I had to do it. )
grub> configfile /boot/grub/grub.cf
After booting into my system, I did this, but the issue still persists:
me@me-devhost:~$ sudo grub-install /dev/sda
[sudo] password for me:
Installing for x86_64-efi platform.
Installation finished. No error reported.
me@me-devhost:~$ sudo update-grub
Generating grub configuration file ...
