I have an HP Probook 440 G3.
I was previously dual-booting Linux Mint Cinnamon 18.3 with no issues for about a year. Then I started getting the "No boot device found" and other errors. After trying many solutions and finding no solution I decided to wipe my whole hard disk and fresh install Ubuntu.
I freshly installed Ubuntu 18.04 LTS, but I am still facing the errors. My whole filesystem goes into read-only mode after an hour of use and I face this error when I try to reboot the system.
Sometime I am able to again boot into my OS by doing a force restart using Ctrl + Alt + PrtScr + RSEIUB. Otherwise I have to boot into a LIVE OS and do a
fsck on /dev/sda2.
Here are the fsck logs https://gist.github.com/nvzard/aecbc8ef62f268a9b413356cb6e4d2da
The fsck fixes the error temporary but I have to do that again when I face the error after 1-2 hour of use.
Here are results of
fdisk -l https://gist.github.com/nvzard/1b225b192469efcd353b3385cfa454e9
I even tried the solution suggested in EXT4-fs error after Ubuntu 17.04 upgrade but it didn't seem to work for me.
I also did a
smartctl check but got no errors.
Sorry, I don't remember all the solutions I tried because I did try many and I don't remember them.
Please help me solve this problem. I'll post the result of all the commands you want me to try. I have been stuck with it for about a week now and really need my laptop to finish my work. Thanks for your help.
