Using QEMU/Virt-Manager you can just create a new VM and instead of creating a virtual disk you just input the path to your drive manually. In my case it's mounted at /dev/sdb
This will pass your full drive to the VM and Windows will just boot up like magic
Edit: If you already have a Windows VM I would assume you could just edit it and change from virtual drive to your full Windows drive instead. I don't think you have to make a new one
I also considered using Tiny11 and Ghost Spectre but ended up with Revi because I don't really trust Tiny11 or Ghost Spectre. It's super easy for a malicious actor to include malware in those redistributed ISOs.
Of course the same thing can be said about Revi but Revi also offers the option to run their Playbook on a regular install of Windows. Or you could make your own custom Windows Playbook with Ameliorated.
Then there is also AtlasOS which, like Revi, is made using Ameliorated. I chose Revi because they had MS store and Windows defender still working and I like their custom tool. But according to Atlas developers, Windows Defender will be coming back in the next release.
In the end I guess what it comes down to is who you trust. The safest bet would be to debloat Windows yourself.
I am using single GPU VFIO passthrough and it's good enough to game on, especially if you also pin your CPU threads in the VM.
You will lose a little bit of performance but if you really need that extra power you can just switch to bare metal Windows using dual boot
If you don't want the full bloated Windows I can recommend that you check out ReviOS
If you don't want the themed desktop (KDE) then Garuda KDE lite is great. They also offer other desktop environments that I also think is without the skin
I plan to go these route but to also bring in the Garuda repos and some tweaks they make. I am running Garuda right now and it works really well for gaming and I like some of their scripts, like garuda-update
I remember my first time installing Ubuntu as a teenager and the fact that the desktop environment was Gnome made me hate it. At that age and time I wanted something familiar and Windows-like. Since then, 13 years ago, I always hated Gnome (and Ubuntu) and I don't feel like that is going to change any time soon.
The new SteamOS opened my eyes to KDE Plasma and now I am running Garuda on my main desktop. Eventually I plan to switch to Arch and "make my own distro" or just use SteamOS once it gets official desktop release.
The new SteamOS has good support for touch but unfortunately it has no official release yet. HoloISO should be okey as long as you don't use Nvidia (because of wayland)
I would guess its selling point is that it's easy for beginners to use and look a little like Windows.
My friends dad recommended it to me and I tried it for some time but I never liked and probably never will like Ubuntu.
You can use distros like Arch or Debian as a base and install KDE to it as a desktop. Many distros based on Arch or Debian come with a desktop pre-installed. Like KDE.
My favorite distro with KDE is Garuda KDE lite (it removes the visuals from regular Garuda).
It uses Arch as a base, just like Steam OS and works well for me to game on. Steam OS for desktops is something I think will become popular once the official release from Valve comes.
I can recommend Garuda KDE Lite. I had some problems with pacman keyring being outdated when installing and had to set it up but other than that it works great
