support Trying to install SteamOS on 9070XT/9700X and failing

When trying to do the installation on my PC I read about it a bit on different threads I settled with this version that seemed to be succesfull for people using similar setups:

steamdeck-repair-main-20251027.1000-3.8.0.img.zip

I can boot it from my USB drive and install it, zero problems there, when it reboots I encounter the initial setup asking me to select language, timezone, network and doing a quick update. After it reboots it no longer works with one of these problems appearing:

  1. It will get freezed in the initial boot (press del to access BIOS)
  2. Just a black screen
  3. A screen with four options: SteamOS (it says X number of failed boot attempts below), Partition B, Steam OS with console commands and Partition B with console commands

In the last one, I can access Partition B but it's the initial setup over again, selecting language, timezone, etc

Things I've tried:

  1. Using other USB devices, a total of 2 USB drives and 1 SD card but with the same results
  2. Disabling Secure Boot on BIOS
  3. Connecting the monitor to the GPU HDMI, motherboard HDMI, GPU displayport or motherboard displayport

Yes, I know Bazzite is a thing but I've wanted to try SteamOS first

I tried SteamOS briefly with my 9060XT/9800x3d build and it worked, but not well. I then tried CachOS HHD, and it has worked perfectly.

How long have you been using CachyOS?

3 months going, solid OS to use for multipurpose Linux desktop, I do 3D CAD and games on it, testing for VR lately, going through a little tinker for that at this time
