Yesterday I updated my system. I don't update my system everyday (maybe once a week). I don't know what I updated, but everything worked fine, till I rebooted my system today. Which ended with my main image not been abling to boot.
I post more details in a sec.
APPEND root=/dev/sda3 ro nvidia-drm.modeset=1 modprobe.blacklist=speck vga=0x034b
that was the line for my system till today. This doesn't work anymore. I got dropped to an emergency shell. I post more details in a sec.
