Hi guys, basically as the title says I want to make external SSD drive with “Windows to Go” for the stuff that I really need Windows for unfortunately (proprietary CAD software) but there is no software for making this on Linux that I can find
Edit: typo
You can use something like virt-manager to mount your USB as a hard drive within the VM then install it from an ISO file.
I would recommend something like Tiny11 for this, but make sure to install the appropriate drivers for your hardware first (or at least have the installers ready for when you reboot).
