Ubuntu 16.04/17.10 Boots to Initramfs

I am running Ubuntu 16.04 on a HP Pavilion Laptop 15-AW004NA. It ran initially for a couple of weeks fine, but now only boots to initramfs. I have re-installed Ubuntu a few times, it will typically work once or twice. Then crash whilst doing a normal operation such as web browsing. After which it wont boot past initramfs.

I have tried: -

manually running the fsck (with -y command it cycles through thousands of commands and CPU hikes up) re-installing Ubuntu 16.04 (encrypted and non-encrypted discs) installing Ubuntu 16.04 then upgrading to 17.10 installing Lubuntu 16.04

I have checked the hard drive using Smart Data and Self Tests, results looked fine.

Live boot works fine with Ubuntu and Lubuntu.

Any ideas how i can debug further???

Cheers Lizard

Solution 1:

To check the file system on your Ubuntu partition...

• boot to the GRUB menu
• choose Advanced Options
• choose Recovery mode
• choose Root access
• at the # prompt, type sudo fsck -f /
• repeat the fsck command if there were errors
• type reboot

If for some reason you can't do the above...

• boot to a Ubuntu Live DVD/USB
• start gparted and determine which /dev/sdaX is your Ubuntu EXT4 partition
• quit gparted
• open a terminal window
• type sudo fsck -f /dev/sdaX # replacing X with the number you found earlier
• repeat the fsck command if there were errors
• type reboot
