When I try to run the Linux Mint Installer, I get several seemingly random errors at various points throughout the process. I have tried several ISOs flashed using Rufus, Ventoy, and Balena Etcher to several different USB drives plugged into several different ports, verified the checksum hashes, disabled fast boot and secure boot, and everything else I can find online. It seems no matter what I try the installer crashes. Below are some of the errors I am running into, I'm not able to get further into the install process anymore to verify what those error codes were later on.

I am not 100% certain how to obtain log files anyone may need to help troubleshoot, but any assistance would be greatly appreciated.

the last 3 lines tell you

#

it's very simple. the installer sees no internal drive.

#

if you run lsblk -o name,type,model,label,size you probably won't either

probably point 4

When I go in disks, all of my internal drives are detected. I’m not home right now, so I will check later but is it possible its just not mounted?

void shore if you run `lsblk -o name,type,model,label,size` you probably won't either

I ran this command and all my internal drives are present

I also just got another error:

Before I ran the installer this time I used GParted to create a partition for mint that's 130 gb

if u already created ext4 filesystem, then u can leave this 'format' tickbox off, but mountpoint must be set

#

I'm not even getting to the installation type page, it crashed after the keyboard layout page.

void shore Dec 29, 2025, 6:23 PM

#

#

well that is fine

#

no reason it should crash.

cunning folio Dec 29, 2025, 6:31 PM

#

This time it didn't even get to the first page and it crashed.

#

your other options: verify the ISO integrity on the usb flash memory itself

#

use other usb, use other ISO (mint 22.1) , or LMDE 7

#

LMDE uses different installer but still operates much like the ubuntu version

if u have a whole bunch of internal drives, power-down and unplug them ALL, except the intended target

What flasher did you use?

#

Etcher or Rufus?

#

oh you tried all of them

#

which version of mint is this?

cunning folio Dec 29, 2025, 9:31 PM

#

22.2, I'm trying LMDE 7 now and it gets all the way to Copying Files but then the whole system freezes but the slideshow keeps going which is weird

void shore Dec 29, 2025, 9:33 PM

#

give time

#

install on hdd takes about 25 minutes

scarlet night Dec 29, 2025, 9:34 PM

#

it feels like a programming error on the devs' side

#

report this on ubiquity's github

LMDE 7 was able to install. I'm still not sure why Linux Mint 22.2 didn't work, but regardless I'm successfully running Linux on my PC now.
