There is a game I am considering getting; it has been out for a few months now, and the devs are specifically blocking it from running under proton with a Kernel Level Anticheat which specifically blocks linux.

Folks on the discussion boards made the point tht it is technically possible to install windows for just one steam game, so I am looking for a guide on how to do that?

I’ve heard that if you don’t activate windows, you can still use it, and if you get the LSTC (?) Version of windows, it is not so annoying.

Does anyone have a guide for how to install windows alongside linux for one game?

If we have a discussion in the comments about whether it is tactically appropriate to give money to a game corporation that requires windows, i guess we can, but i would rather learn how to install windows in the least annoying way possible.

    I am not an expert on Windows game rootkits (or Windows in general…), but would it perhaps run in a VM?
    At least then you wouldn’t have to do a “real” install…

      Nah, that used to be a solution a few years back if you had the patience to setup GPU-passthrough with a single or two GPUs. But these anticheat rootkits now detect a running VM and deny you service either way.

      Dualbooting Windows 10 LTSC with massgrave activation seems to be the best option for now if you really nee…want a Windows installation with GPU acceleration. For Nongaming/Rendering tasks: Winboat.

        I played Forza Horizon 6 pirated like this. It isn’t an easy solution, but it worked for that one. I’m not saying it’ll work for anything else, but it does work for Denuvuwu.

      Get the Windows 11 IoT LTSC specifically. IoT is better according to nassgrave, and Windows 11 so you get good compatibility with new games. Not much debloating is needed, just use WinUtil by CTT and tweak/disable shit.

      This is what I do, just a spare nvme drive thrown in an external enclosure. Rufus has an option called “windows to go” that installs the iso as opposed to making a bootable installer, and it gives an option to block Windows from overwriting local disks to avoid the boot loader issues too. Has worked quite well up until a point recently where it just refused to boot anymore with an unhelpful error despite not having been touched in months. No updates or changes since it worked before. Good ol windows…

        I was installing Win10 Pro to a SSD that I would stick in an external case. Would work, for a while, but eventually would get an error and would be unable to boot, or repair it. Windows seems to be designed to know when it’s installed on an external drive, and to hose itself out of spite. I gave up after the fourth time, resigned to the fact I just had to find an alternative CAD software package that I could access from Linux.

          Interesting. I suppose I’ll see if it happens again, luckily not too big a deal as Windows was more a convenience for a couple utilities I use, already found a Linux friendly way for one of them thanks to it borking itself recently. If they’re intentionally doing that and giving me an excuse to rid myself entirely of Windows, I guess I won’t complain too much ahaha. I just chalked it up to the usual Windows shenanigans

    If you must run Windows, do it on a completely separate device if you can. That way your one game that’s DRM-locked to Windows can stay on its own machine without Windows getting hostile to your Linux install like in a dual-boot.

    If you don’t have/can’t obtain a separate device for installing Windows on and you must dual-boot, the safest way to do that is to disconnect your Linux drive(s), install Windows on its own fresh drive so it can have its own boot partition and its own bootloader, reconnect your Linux drive(s) after your Windows drive is finished setting up, and then set your Linux bootloader, usually GRUB, to query your Windows drive and let you pick it to boot from, that way hopefully Windows stays on its own drive and its own boot partition and doesn’t try to screw over your Linux drive and its boot partition.

      What i half remember is that if the windows installer (or Linux installer for that matter) detects an EFI boot partition, it will write to it, regardless of what the software says it will do, which is why we have to do this.

      But once windows is installed and grub uses the chainloader method to pass the boot to windows’s bootloader, does that mean that future windows updates will restrict their changes to the windows bootloader? Basically, what risks should I watch out for if Windows is on a drive in the same computer as linux?

      I have tried to have separate computers share the same desk, speakers, keyboard, mouse, and dual monitors in the past, but it is not easy or cheap to do well :/

        GRUB just queries it so you can pick it and boot from it, it should still be on its own drive if you do as I described with it, or at least it did last time I dual-booted, which was forever ago.

        Also, dual booting is much easier when using Windows 10 with Linux than using Windows 11 with Linux.

        If you purely want Windows to have minimum impact on your Linux system then avoid Windows 11.

    You can do one of three, for different levels of ease and performance:

    1. Install boxes/gnome-boxes, install the windows os on a virtual machine. Just press the plus to choose an iso file and go.
    2. If you have an extra hard drive, you can install windows on that hard drive, and have to set up grub to recognise it.
    3. Change the partition size of your hd using a live cd/usb version of Linux (you can’t change partition size on partitions that are in use) , make a new partition and install windows on that partition. Add this new OS to grub.

    You will need to do further research on some of the stuff I said, but I have you the correct things to look up.

    They go down in order of difficulty. Boxes will be less efficient but easiest. The other two have the same efficiency, but the second is a bit more challenging

      I wouldn’t suggest Boxes for gaming. Even if it could do a GPU passthrough, I don’t think current anticheat games, like what OP wants to run, play well with that.

    Maybe what you want to hear, but I once bought Marathon because it wasn’t declared that GNU/Linux is blocked again, like Destiny 2 was. I requested a refund on Steam and 30 minutes later was granted. It’s not worth the hassle for one game, IMO.

        I stopped bothering reading specs because my gaming pc (bazzite—yeah I know, I’m extremely lazy) just runs whatever I throw at it. I feel like you’d have to very aggressively develop a game exclusively for windows too manage to get it to not run on Linux these days.

    If you want to dual-boot Windows and Linux, I strongly recommend that you install them on separate devices, and physically disconnect your Linux device. It’s a pain in the ass, but Windows Update has a particular appetite for bootloaders and will eventually eat whatever you have on your EFI partition (including the Linux kernel and ramdisk) and replace it with its own.

    Otherwise, you can use Chris Titus’ winutil script to delay or completely disable updates, and also to debloat the system and disable anti-features like telemetry and the start menu search.

    Not sure if this applies to LTSC, but if you can, install a European edition of Windows (-N suffix) and set an EU location and timezone, it will allow you to more easily uninstall components because of EU regulations.

      I can confirm you only need to physically disconnect the non-windows target drive during installation, and as long as you offline the remaining drives after connecting them, windows and other drives will be fine with updates (THIS is the most important part, do it in Disk Management on first boot into windows).

      I’ve run two Windows instances for years, through multiple OS major updates and never had problems with this setup, before doing the offline drive change to each of them, they would both fuck over each other (I had one for work and one for personal).

      One thing I did that may be necessary, is I didn’t let a boot loader handle the dual boot, I only used BIOS to manage changing the boot target when switching over - I was doing dual windows boots at the time so this may actually be fine with grub, so ymmv on that front.

      I physically disconnected all drives to force the EFI partition on the actual Windows drive. It still shat all over boot settings after the first major update.

      Someone recommended I try rEFInd and it’s been great. No update has forced me back into the UEFI to set boot order since.

      Might be an ASUS MB thing, I never figured it out or bothered afterwards.

        There are interfaces that allow a sufficiently privileged process to change EFI settings from the OS. Those settings are stored in the UEFI chipset, independent from the bootloader.

            Don’t even get me started on fucking Gigabyte. With all my heart,

            FUCK GIGABYTE.

            It is the single worst manufacturer I’ve ever had to deal with in both a personal and professional capacity. We’ve had to RMA half a classroom over the last two years because of busted motherboards. In separate incidents, two power supplies violently self-destructed and took the motherboards and CPUs with them. My own Gigabyte 2060 Super’s fans had to be replaced within two years because the bearings were crap.

            Worse, even the motherboards that didn’t mercifully explode are a fucking chore because Gigabyte’s UEFI implementation is the worst on the fucking planet. No two versions work alike. Some options are in completely different menus. Sometimes CSM or SecureBoot are busted out of the box. If PXE is enabled (which we have to use frequently), it will ALWAYS put PXE at the start of the boot order. And if it can’t connect to a PXE server, it doesn’t fall back to the next boot option. It gracefully shits itself and sits on an error message until someone manually restarts it and interrupts the process.

            Fuck Gigabyte.

            Why it matters is because there are different workarounds for different games. Some can run just fine in a VM. Others have wine tricks or proton tricks that you can use. Still others run dockerized on winboat.

            Being evasive just means that people have to give you generalized solutions that may or may not work for your particular scenario. Help could exist for you, but you’ll never know.

    Put the installer on a USB, remove your Linux drive (because you should install it on a separate drive, and Microsoft will infect your boot partition otherwise), and run it. That’s it.

      I’ve had Windows cause enough problems with wrecking my Linux boot partition to not want to try this again. I wouldn’t recommend it to anyone. It works fine most of the time. But I’m not willing to risk that rare occasion when windows renders my Linux drive unbootable. Maybe there’s a way to fix the boot partition and I haven’t figured it out. But restoring my whole system is so annoying that I wouldn’t risk it.

      So i would recommend that the best option is to consider just ignoring that game and playing the endless number of great games out there that run on Linux already.

    If you decide to go the dual-boot route with shared storage between windows and Linux, then I recommend using a btrfs partition. You’ll have to install WinBtrfs to use it on windows, but the experience is a filesystem that’s much better than ntfs on both windows and Linux.
