I have a dual boot windows 10 - linux system and just installed ubuntu 18.04 a couple days ago. The error in the picture below just started showing up.

It doesnt prevent me from using ubuntu or windows, just curious what's causing it.

I googled around a bit - ended up running bad blocks, gnome disks, crystal disk info and chkdsk in windows .. nothing so far points to the drive failing. Any help would be appreciated.

  • It does sound like a hdd/sdd issue to me, so I'd ask your hdd/sdd electronics to provide info about it's health (ie. view your SMART or self-monitoring analysis & reporting technology which is on almost all drives (excluding a few low-end drives)). You can view the data with smartctl or gnome-disks (gnome-disks is a gui tool & provides far less data so is easier to understand). Refer help.ubuntu.com/community/Smartmontools for more info

  • I added a picture above. I used gnome-disks again and that was the result. I will give smartmontools a try and report back later today or tomorrow

  • I followed help.ubuntu.com/community/Smartmontools. It found no errors. Added picture to original post

  • You might be effected by this bug: bugs.launchpad.net/ubuntu/+source/grub2/+bug/1553687 Aug 5, 2018 at 1:22
  • I see. Thanks for the help. I'll keep an eye out for a solution but it doesn't seem to effect my system negatively so I'm going to just leave it alone

Now this seems like an old question by now, but since alot of people around the internet seems to have this problem, I'd like to post how I fixed the problem.

I had two problems:

  1. can't find command "hwmatch"
  2. failure writing sector 0x... to "hd0"

The first error I fixed by running:

  1. sudo apt install grub-efi-amd64
  2. sudo dpkg-reconfigure grub-efi-amd64 Through the whole reconfigure process, I just pressed "enter"

The second error, the same as yours, I fixed by changing the boot mode in BIOS from "UEFI" to "legacy mode"

try upgrading to an SSD or SSHD. hard disks does'nt work well for laptops (SSHD's also, but it's better than hard disks) . if you are on a desktop, try a new hard disk or SSD.

  • I have the same error using a laptop with an SSD. Sorry, but simply stating that "hard disks does'nt work well for laptops" is just plain non-sense. Also you don't say why. Jan 26, 2020 at 10:58
