Dead Ubuntu desktop - [RESOLVED]

Earlier this year I had a desktop built up by a local computer emporium for a friend. In particular I specified an SSD primary drive and HDD secondary (to be used for backups), and I installed Ubuntu 16.04. It worked very well and my friend was very pleased with the speed.

Recently she complained that the PC was ailing and then became dead, as in no lights or fan – nothing – so I have just picked up the PC from Oxford and brought it back to Yorkshire. I guessed a dead power supply so opened up the PC and discovered a batch of wires had come adrift; specifically those that run from the front panel to one end of the motherboard. They were:
Start button, LED, HDLED, USB – which explained why the start button didn’t operate. My guess is that my lady friend got someone to “have a look at it”, but I’m too much of a gentleman to enquire!
I connected them all up (thankfully they were labelled!) and pressed Go: Lights on, fans whirring, POST then error:

error no such device: ec20bf64-f0e4-41ac-b17c-c52eed11994e
entering rescue mode …
grub rescue>

…and I couldn’t think of any likely commands except “start”, “quit”, etc., which weren’t recognised, so I checked the EUFI setup from which I extracted this:

[i]UEFI Set up utility
i3-2120 cpu
8GB

Storage
SATA2_0 Toshiba THNSNF 128GCSS (SSD)
SATA2_1 TSSCORP DVD-RW SH-216AB
SATA2_2 -not installed
SATA2_3 ST500DM002 – 1BD142 (HDD I guess)

Boot options
#1 PM: Toshiba…. (SSD)
#2 SM: TSST…. (DVD)

Boot BBS Priorities
Boot option 1 PM: SSD
Boot option 2 SM: ST500 (HDD)
[/i]

I can’t see anything obviously wrong, and at least the reference to “grub” is encouraging as it’s found the right drive, but the “no such device” is worrying. The “boot options” and “Boot BBS priorities” don’t match, either.
I would be very grateful for advice on how to find the cause of the problem - and then solve it, of course.
Thank you.

Can you boot to a 16.04 LiveUSB/LiveDVD and post the output from:

sudo fdisk -l

and

sudo blkid

I’m going to need you to run those commands again but prefixed with “sudo” as in my last posting … and post the output;)

can you also run:

sudo  mount /dev/sda2 /mnt

then post the contents of

gedit /mnt/boot/grub/grub.cfg

and

gedit /mnt/etc/fstab

My apologies, Mark - a senior moment. I get a lot of those.
I have done as requested.

Okay let’s try reinstalling GRUB … boot to a LiveUSB/LiveDVD and run these commands in sequence

sudo mount /dev/sda2 /mnt

then

for i in /dev /dev/pts /proc /sys /run; do sudo mount -B $i /mnt$i; done

then

sudo chroot /mnt

then

grub-install /dev/sda

then

update-grub

then hit Ctrl+D to exit the chroot environment.

Now shut down the PC … remove the LiveUSB/LiveDVD … and see if it will boot normally

No, Mark - I get the same error.

As the Live USB can access files on both the SSD and the HDD, does this indicate that I could simply re-install Ubuntu? After all the previous owner no longer wants the PC.

Well you could yes.

Or we could try to fix the UEFI bootloader

That said a reinstall may be a better way forward because you’ll only have to clean her stuff off if we fix it

If you think any of our readers might be interested in how one might fix the UEFI bootloader then I’m game; but it’s a lot of effort for you.
Based on the info that we have, do you reckon that a re-install is likely to be trouble free? … and will that fix the bootloader as well?

Yeah I can see no reason why a reinstall wouldn’t work so you as well just go ahead and do it Keith :slight_smile:

If on the other hand you want to try fixing it … boot to the LiveUSB IN UEFI MODE then post the output from:

efibootmgr -v

Screwed that up…just trying again…

I can’t for the life of me see where the UUID ec20bf64-f0e4-41ac-b17c-c52eed11994e is coming from…

Has the hard drive ever had a Linux distro on it ?

What happens of you disconnect the HDD but leave the SSD attached … then try to boot, selecting the SSD from the EFI boot menu ?

No; the system had Windows 10 on the SSD when I bought it just to demonstrate that the system worked. I installed Ubuntu 16.04 on the SSD then had to then delete the HDD partitions to get rid of whatever Windows had put on it (& formatted in Ext4) and named the volume “Data” for backups etc. It all worked fine for weeks then died.

I have disconnected the HDD but when pressing F11 at the UEFI screen to select boot device, the system went straight to a black screen with the following text:
“Reboot and select proper boot device or insert Boot media in selected Boot device and press any key”

Swapping the HDD lead to the SSD gave the same result, but that it didn’t go to the boot order screen when pressing F11 is significant, I feel.
This is beginning to look difficult.

Probably simplest to just reinstall at this point Keith

Sounds good to me, Mark. I shall report back tomorrow.
Meanwhile: many thanks for taking the trouble to try and sort it out.

The re-installation of Ubuntu 16.04 went OK. Although it would have been nice to know what the problem was, one can have too much of a good thing so re-installing was definitely the best way forward.
I am now the proud possessor of a really fast PC and my lady friend will regret returning it to me!

As usual I am indebted to you, Mark, for taking so much trouble. Many thanks.
Keith

Dunno why, I didn’t get it working this time :wink:

Can’t win 'em all, our kid! :wink:
