About a year ago someone slammed my computer screen and it is now not allowing me to loggin due to a kernel panic and I do not knowhow to fix. It says kernel panic - not syncing : VFS: Unable to mount vs on unknown-block(0,0). I am using linux as my OS and even when I try to boot it on recovery mode the same problem has come up. I have also tried booting it with older versions but that also doesn't work. I have done a functional test using grub and tests are passed. My laptop is a Lenovo T420. I dont know what my RHEL version is but I do know I dont have a resue boot mode. I also do not have ubuntu. I was just wonder in if anyone could help me out and dumb it down a lot because I am very very new to working with computers, this is the first time I have tried to fix one.
