I moved to Ubuntu 18.04 around January 20th 2019 and it's been working since installation until now, it suddenly crashed and became unusable outside of a terminal. (root mode in recovery or with nomodeset and CTRL + ALT + F2).

I've been trying to fix the issue with the help of various forums but it seems nothing is helping, most revolving around the graphics driver, so I felt I should reinstall.

Now attempting to reinstall, all issues persist when attempting to install Ubuntu 18.10 as well:

* logs about noueavu read faults

* errors on installer startup for a slideshow

* frozen screen when nomodeset argument is passed

* file errors on disk (what this is about)

When I check the disk for errors (via the installer USB, bottom option) on my personal laptop is returns that there are errors in 1 file.
When I check on my work laptop, it returns the disk is completely fine, my work laptop runs Ubuntu 18.04 as well but hasn't had any problems.

I can also confirm following this tutorial that there is nothing wrong with the image, the same USB was used when trying between both laptops.

To create the bootable USB I used the Create Startup Disk tool preinstalled on Ubuntu.

Hardware:

GTX970m

i7-4710HQ

32GB RAM

512GB SSD (SATA Samsung 850 Pro)

(Doubt it matters but for what it's worth.)

Installing from a 64GB Samsung Flash Drive

Any ideas what would cause file errors to be found in one computer but not another?

Notable BIOS settings (if that helps?)

* Legacy USB enabled

* XHCI Pre boot enabled

* Secure boot enabled EDIT: now disabled

* CSM disabled

* Fast boot enabled

Edit:

Owned SSD for around 2-3 years, not sure if it matters but mentioning anyways.

I was able to install Windows successfully and in device manager I'm able to see my GPU just fine, there was no problems in installation.

Ubuntu 18.04 however still has all the problems when trying to install, or try from the USB, despite all options working perfectly off the same USB on my other laptop.

This answer only works in my case, it seems most of the above was correct and would work if the GPU was the issue but it wasn't for me!

The reason I had issues on my laptop and not on others is because one of my RAM modules were failing.
Upon running a memtest (possible via Grub menu when booting into installer in BIOS mode), I discovered one of my 4 RAM modules were throwing tonnes of errors.
I removed it and all problems solved, unfortunatly I'm down 8GB of RAM too but that would explain all the various segfaults and errors.

EDIT:
An update, if there is anyone who has suffered memtest failures like how I did, if you happen to have Corsair RAM then you can contact them and have it RMAed, as Corsair have unlimited warranty for memtest failures on their memory.
