Yesterday night, I installed Ubuntu, it was working fine that night. Today morning I opened my laptop for my class, it was working fine, but after some time my class got struck. And it opened CLI(command line interface) and in some text, it showed I/O error. So, I though a restart of he computer would be a quick fix, but when I restarted, It opened CLI again and it showed COMRESET failed (errno=-16). I still have the bootable drive, so if you want me to do something with it, I can do anything with it like reinstall, or anything else what you would recommend to solve the problem. I tried to re-install ubuntu 20.04 LTS but it showed me an error that it is getting an I/O error. But, it is working fine when I am in trying mode. Please say something, what can I do to fix it, I need to fix it fast!
(And also to mention, my laptop had a little accident, when I was holding my laptop and moving to a room, it fell on a bed, not too far in height, not too near, it fell from a distance of about 30cm)
