Yes, I have done a few things already, including memtest. I’ll copy from the forum:
The things I have tried:
Updating my BIOS.
The ISO I downloaded has been md5 checked, all fine. I have also tried 2 other ISO files from 2 other mirrors - same.
Three (3) USB drives to install Mint, ranging from 8 GB to 24GB.
Installing with or without multimedia codecs.
Turning on secure boot before install (I was desperate, found a forum post with a similar error message, later I found out that it was for a different reason).
Turning off secure boot before install (I found a different forum post where the exact opposite was recommended - later I found out that it was for a different reason).
Installing in compatibility mode.
Offering a sacrifice to Xebeth’Qlu, tormentor of souls.
Running gparted before install, deleting the previously half-installed partition, formatting it myself to ext4, then running the installer.
Splitting the aforementioned partition into a 16GB swap partition (I have 16GB RAM) and leaving the rest of it as ext4 (mounted at “/”).
Running chkdsk -f on the SSD containing the MBR+Win10, then rebooting the PC twice, according to one of the error messages in my post below (then trying to install again).
Tbh you might have failing RAM or something. Have you run Memtest?
