I'm going to switch from Windows 11 to Linux soon but first I wish to backup every every data and config files I can in my current Windows installation, even those that wouldn't natively work in Linux. I know the \Users folder is important to back up, but I don't know what other directories I am missing.

IT guy here.

The best thing to do is first to verify that bitlocker is turned off, then remove the drive from the computer, replace it with a new drive, and install Linux on that.

Then take the old drive, get a USB enclousure, install the drive and plug it in to your Likux machine, you should now be able to access the Windows files

I have two physical drives so I can dual boot. I've already disabled Bitlocker so I can directly copy the Windows files and folders to the Linux drive. The backup is temporarily kept in an external drive for redundancy in case I screw up the transfer process.

Am I covered in a setup like this?

As a general rule when it comes reinstalling a computer while preserving data, I will always recommend removing all drives but the boot drive during install.

Especially since Linux and Windows identifies hard drives in a very different manner.

This is done to prevent any mistake and make it easier to understand what drive contains what data.
