Help! My Ubuntu is booting to "press enter for maintenance"

[melao]

For some reason my pine is booting to the following:

press enter for maintenance
(or type Control-D to continue):

I am using "xubuntu-xenial-mate-20160528-longsleep-pine64-8GB "

I thought that maybe it could be a runlevel problem, but I cannot find /etc/inittab  and I tried using init 2, but it does not work.

I also tried fsck -y , but the system is mounted, and I dont dont know what I can and cannot unmount :/

Please help. I dont want to reconfigure the whole system again :/

Ok, I reinstalled everything...
