I have Ubuntu 16.04 and I am facing the following problem: I tried to open my PC and got an error concerning the filesystem that suggested to do fsck manually. I did:
fsck /dev/sda1
And fixed all the errors by saying yes. I then tried to reboot, but my system freezes as it is shown below:
A TMP error (6) occurred attempting to read a pcr value
Systemd[1] : failed to isolate default target: Unit multiuser.target not found.freezing execution.
What should I do? Is it a kind of systematic Ubuntu error or can it be my motherboard for example?
I really need your help cause I am new to Linux and the PC belongs to my research team not to me... so terrified of losing data!
