That being the case, your inxi output as it stands isn’t entirely useful. When you are able, please run inxi -zv8 from within a chroot environment.
It’s not practical to copy/paste the command output directly to the forum, however, you can pipe the output to a text file instead, like this:
inxi -zv8 > ~/my-inxi-output.txt
Then copy the whole file to a USB (for example) and copy/paste it from whatever computer you’re currently using to access the forum.
Yes, you can likely put that into motion while in chroot.
If you had the foresight to place /home as a separate partition when you initially installed, you likely won’t even need to move it’s content.
The trick is to use the manual formatting method and remember not to format /home - your files and most application specific settings would be found again by the new system, considering they are all stored under /home.
Of course any preferred system settings would need to be configured, and your applications themselves would need to be re-installed.
If /home is not on a separate partition, the entire content can still be copied to (an ext4 formatted) USB temporarily, and restored to the new /home after install.
There will likely be many who will be able to guide you through that; the following tutorial also has a few useful suggestions;
The latest non-Beta BIOS is recommended.
While I used the experimental UEFI BIOS myself (on my old Z68XP-UD4) without any issues, I imagine you’re comfortable with BIOS/MBR, so stick with what you know.
