LM 19.3 to 20 failed miserably

Hi guys

Linux Mint 19.3 to 20 on ASUS laptop

I did an upgrade on my laptop and it seemed that everything went fine and after reboot I ended up with (initramfs) and a blinking marker.

Using advanced options doesn't matter, none of the choices makes it work.

Using Timeshift to restore my backup doesn't work either and all I get in the startup now are 4 choices:

Linux Mint 20 Cinnamon
Advanced options for Linux Mint 20 Cinnamon
Memory test
Memory test serial

I don't know what information you need to help me on this so just tell me and I'll get it.

Thanks
