I have a dual boot system installed following blog - Ubuntu 16.04 with windows 10 along with an additional swap partition. It was working fine for several months and something like no boot device detected
appeared after a shutdown (I'm not sure about the reason, but I had installed somethings Software Updater suggested). On the next restart, monitor went to power saving mode and I had to shutdown using the power button. It remained the same for two other attempts, then I reconnected everything from RAM, SATA cables, power cables etc and cleaned dust all over.
Now, system shows some message like:
watchdog=1 notification connection refused
And cursor blinks on a black screen. Some type of repeated messages are printed at almost same time intervals. Starting words are:
Oops
Modules linked in
CPU
Hardware name
Task
---end trace ---
Along with some HEX codes and ?
symbols.
If I tried to login with Ctrl + Alt + F*, it prints:
/dev/sda3: recovering journal
/dev/sda3: clean *** / *** files, *** / *** blocks
On the next keypress:
agetty[949]: segfault at *** ip *** sp *** error 14 in locale-archeive[***]
I have tried to see the contents from Grub menu. There is (hd0,msdos3)/
with /boot/grub
and other system directories. (hd0,msdos2)
and (hd0,msdos4)
with /home
contents and windows
partitions. Remaining (hd0,msdos1)
shows unknown filesystem
.
How can I correct the errors? Or at least copy the contents and reinstall Ubuntu?
