run installer curl -L https://install.pivpn.io/ | bash

• configure wireguard
• setup non root user
• Set a port

Create a user with pivpn add

Example:

root@funhaus:~# pivpn add
Enter a Name for the Client: user.name

The conf file can also be found in /home/user.name/configs

Copy the conf to your machine. Install WireGuard and use that conf.

In qbitorrent you should make sure the application is set to use the VPN network, otherwise it’ll use both. Go to Settings > Advanced > Set Wireguard from “Network Interface”

If you install Linux first, Windows will see a grub partition on install and go “Oh, let me use this too” disregarding it’s for an entirely different OS. Then when grub is updated by Windows it goes “What’s all this crap, nah, we don’t need any of this” and then your Linux distro can’t be booted.

I’ve dual booted for years, never had an issue because I installed Windows first.
