Ok, so I screw up my last actualization of Ubuntu - I was not paying attention and during this I encountered a lot of problems, in the end my laptop stopped working. I tried to reanimate it, but to no avail - it seems that my entire system is not responding.
Therefore, I tried to repair this by installing new Ubuntu - however, during installation (no matter my choices, be it install completetly new or recover old system) i keep getting „Errno 5 - input/output error”. I changed my USB stick, i used different entrances, I checked my ISO file. It seems the problem may be connected with problems on my filesystems.
I tried to check my filesystems with fsck commands, but it keeps saying my that i can’t do that and All answers on the internet tell me, that i need to reboot it to kill all my processes to be able to umount it. However, if i do reboot it, i can’t go back and have to boot it from the start. Is there any other way to kill all programs or to remove Errno5 problem?
