This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

  • I'd suggest booting a 'live' system (eg. Ubuntu install media), then fsck [file-system check] your disk partition(s) to find & correct any errors (which is possibly of untidy power-off). After this, a reboot will most likely find it back to normal. – guiverc Apr 9 at 7:20
  • Okay, thanks @guiverc . Can you give step by step guide for this process or any link? I'll try this after get my live usb-boot – fulltimecoder Apr 9 at 8:34

  • Look at all the answers of the duplicate @fulltimecoder : your disk just disappeared (check cables or replace disk but first follow the duplicate) – Fabby Apr 10 at 11:25

After strugling with tutorial around Askubuntu and from another sites unfortunately it still the same.

Then I tried to access recovery process and upstart on previous kernel version in the list on advance option page of start menu. It's working and everything accessible including the internet by command below.

sudo nmtui

Then from command line I remove active kernel

sudo apt remove linux-image-x.x.x-xx-generic linux-headers-x.x.x-xx-generic

Reinstall again the latest and perfect one of my Ubuntu version

sudo apt-get install linux-generic

Then reboot,

sudo reboot

Everything working like before in my case.

  • I still suspect it's related to a fsck. Every 30th boot the system will force-check itself (the count can be altered but 30 is default) which achieves what I suggested. I suggested 'live' media as it's easiest when the drive/partition is unmounted (the install-media will be mounted not your hdd/sdd) but if the 30th fsck wasn't your fix (which should be performed after a incorrect shutdown as your describe) you may have issues unfixed that will re-occur so I'd still suggest file-system-check be performed (because of accidental shutdown) – guiverc Apr 10 at 2:49
