boot - Ubuntu falls in emergency mode after upgrade 14.04 -> 16.04 - Ask Ubuntu

i have upgraded ubuntu 14.04 16.04. after loading falls in emergency mode. unfortunately couldn't copy paste output of journalctl -xb command (it seems journal exists in emergency mode). have written errors on piece of paper , copy errors one:

systemd_udev[294]: specified group 'pugindev' unknown nvidia-persistentced[564]: failed query nvidia devices... syscmd[1]: dev-disk-by\x2dlabel-data.device failed mount /filearchive. special device /dev/sdc1 not exists kernel: hid-generic 0003:046e:6000.0002 usb_submit_urb(ctrl): failed -1 error connecting consolekit gnome-session-binary[1019]: error: failed connect sys. aborting 

on nvidia: have gtx660 series card.

how solve ?

update: according @heynnema's advice, publish outputs:

and 1 blkid:

about disks in few words: 1) 128gb ocz-vertex-4 ssd disk linux placed (/dev/sda)

2) 2 tb wd green. /dev/sdc. have 1 ext4 partition. mounted @ /filearchive

3) 2 tb wd green. /dev/sdb. have 3 partitions. first 1 /dev/sdb1 contains windows. next 1 /dev/sdb2 ext4 data partition mounted /filearchive2. last /dev/sdb3 lvm partition.

by way if choose on load following: boot menu -> advanced mode -> ubuntu 16.04 (upstart)

then able load system. using startx after ubuntu falls command line mode. disks mounted correctly.

couple of issues...

1. in /etc/fstab, you're mounting sdc1 ext4 when looks might ntfs, or it's possibly corrupted
2. your /etc/fstab mounts filearchive(s)s device, instead of uuid. can cause intermittent mount issues. change /dev/sdxx uuid={the value taken blkid command}
3. your /etc/fstab mounts filearchive(s) in unusual place. should @ /mnt or /media.
4. if sdc1 ntfs, may have unclean file system, fixed chkdsk in windows (if dual-boot , have windows). you'd want disable fast boot in windows power control panel, , hibernation powercfg /h off in elevated command prompt window

short term: i'd comment out 2 filearchive(s) mounts in /etc/fstab can boot now, , fix them after can boot

keep posted.
