Yesterday I was copying things from NFS to my computer and something was stuck, after a while I tried to restart my computer but it didn't work so i force powered it off.
Now, when I booted the machine, it got to GRUB and after it couldn't boot.
It seems like vmlinuz and initrd loading successfully (no matter what version - 3.13, 3.11 i tried both of them).
all i see at the beginning is empty screen and after a while it sometimes tells me that mount points are not ready (/tmp /boot /):
"The disk drive for [some mountpoint] is not ready yet or not present. Continue to wait, or Press S to skip mounting or M for manual recovery".
except for "/", it warns about all the mountpoints in fstab.
Also can see that "rpcsec_gss daemon" is failed to start.
At one of my attempts it told me that there are serious problems with /, so I used livecd and fsck the disk. didn't find anything special.
My questions are: 1. how can I debug the boot process verbosely and find what cause this problem? 2. what can cause this trouble?
By the way, i have Ubuntu 14.04
Thanks in advance
