If you need to dual boot, you should also use a dedicated disk to prevent Windows from deleting your Linux. It has been known to happen

What, no, socks are step one, while you’re waiting for your prescription.

No, it’s a EFI app I developed in Rust that does a query over multicast UDP and uses the result to select which EFI app (Windows bootloaded (yeah I know…) Or systemd-boot to start Arch)

There’s nothing related to proxmox itself, it’s just there that I host my LXC with the service that responds to the quey.

I boot on a custom EFI app to control my dualboot (instead of systemd-boot or grub) that asks a service on my proxmox server which OS I’m supposed to boot.

Overkill, but it allows me to control my dual-boot without a keyboard in my computer (because it’s a Bluetooth keyboard so I can’t really use it in grub anyway)
