Last Tuesday, loads of Linux users—many running packages released as early as this year—started reporting their devices were failing to boot. Instead, they received a cryptic error message that included the phrase: “Something has gone seriously wrong.”

The cause: an update Microsoft issued as part of its monthly patch release. It was intended to close a 2-year-old vulnerability in GRUB, an open source boot loader used to start up many Linux devices. The vulnerability, with a severity rating of 8.6 out of 10, made it possible for hackers to bypass secure boot, the industry standard for ensuring that devices running Windows or other operating systems don’t load malicious firmware or software during the bootup process. CVE-2022-2601 was discovered in 2022, but for unclear reasons, Microsoft patched it only last Tuesday.

The reports indicate that multiple distributions, including Debian, Ubuntu, Linux Mint, Zorin OS, Puppy Linux, are all affected. Microsoft has yet to acknowledge the error publicly, explain how it wasn’t detected during testing, or provide technical guidance to those affected. Company representatives didn’t respond to an email seeking answers.

    Hey Microsoft: Windows is yours, GRUB is mine. I don’t give a shit if GRUB is vulnerable, I’ll fix that myself if I choose to.

    Mind your own fucking business. The most you should ever do is let me know about it, not try to patch things you aren’t responsible for…

      The update was meant to fix a situation where an attacker would somehow get grub onto a machine that was SINGLE booting windows and use grub to tamper with secureboot. this fix was meant to only apply in single boot situations where it should be entirely unexpected to see grub. as they said, something went seriously wrong.

    I use Debian and I also was affected by this Windows update. I was able to boot by disabling secure boot. I also found this option that apparently fixes the problem by changing the sbat policy using mokutil. But I haven’t tried it out yet. Has anyone got any luck with something else besides disabling secure boot?

      And each time you want to use Windows, you have to go through hoops and updates of Windows and then updates of the applications (and possibly games) to just do the work you intended to boot into. I had Windows for a few years in dual mode too and know the problems of a Windows system that is not used often.

      If you really need some applications, then consider using a VM (however doesn’t solve the updates and usability issue of Windows). Off course some games won’t work, but if its not a game then maybe you can finally get rid of your dual boot.

        At this point, the only thing keeping me back is I have a bunch of files made in Clip Studio Paint that I can’t open in linux, but I think I might be able to run CSP in a VM, if needs be. Not really anything gaming related.

          That’s actually not bad, if this is the only thing (hold on, after looking into a bit it could be a show stopper still). An idea is, if its not too many files, would be to save them from this application in a more universal usable format and not use it anymore. But that comes with ton compatibility issues on itself, so who knows.

          It seems like WINE (the tool that is used as main part of Proton in Steam) can run Clip Studio Paint, but not great (Silver rating): https://appdb.winehq.org/objectManager.php?sClass=application&iId=15102 And then the question is if it will even work well with Wacom devices this way. Also I’m a bit worried if it will work well in a VM too.

          The upside is you can treat it as just another program with a big flat file that serves as it’s hard disk. You can move a VM between computers, they’re universal. Hell you can move it to a data center and hardly notice a difference. You can make a snapshot, try something out, and if it borks, roll it back to a previous snapshot. You can copy the VM any number of times.

          Basically it decouples operating systems from hardware so you can treat a computer like software.

    So glad I recently removed Windows from my former dual boot system completely. Was sick of getting errors during Linux boot up after running Windows for that one piece of software I couldn’t get to work in Wine or Bottles. The culprit I assumed was Windows updates, which I attempted to disable through the registry on several occasions. It would work for a short period and then Microsoft, in all their wisdom, would just reenable updates because clearly they know better than I what I want my system to do. The last time it happened was the final straw for me when I wanted to boot into Windows briefly only to be left waiting half an hour for Windows to apply updates on shutdown. Pissed me off so much I killed the power mid-update, booted up a live partition tool and wiped Windows off my system completely (updating the grub to remove dual boot). That’s when I discovered that not properly shutting down Windows would mark my other drives dirty and make them read only. To fix this I ended up having to insert Windows installation media and pretend like I wanted to reinstall Windows 10 again. Once it got to the stage when it was about to write to the drive I cancelled the installation and rebooted back into Linux. Voilà! Could write to my drives again. To hell with Windows. I’d rather live without that one piece of software and have my system do what I want it to do rather than it second guess me and disregard my instructions. This whole automatic update thing really boiled my piss. At least with Linux I can choose to apply updates when it’s convenient for me to do so.

      I have two pieces of software I cannot live without, to the point that I would rewrite them for Linux if it came to that. Running Windows as a VM using Virtual Box has been a nice experience so far. (Given that both software are not CPU nor GPU heavy and could run on a tree if need be.)

        What two pieces of software, if you don’t mind sharing?

        I ask because a relative who is a software developer could somehow barely finally leave windows, because of WinSCP, which is, afaik, a GUI for secure copy commands. Why rsync or sftp commands cannot be enough for a software developer without WinSCP was beyond me. But perhaps there is something I don’t know about each of these pieces of software.

          BookLibConnect and AaxAudioConverter. I use them do download my Audible purchases. They are both written using WPF (or some other Windows API only GUI lib) and thus cannot be run on Linux. I might rewrite them using the newest C# cross platform library, but that library does not compile native on Linux, only on Windows… (Unless you use the community maintained version).

          I did try to find replacement for both for them but their ease of use and the conversion tool for axx to m4b made it preferable to just install Windows in a VM.

          As for WinSCP, it is a SFTP/FPT client that is really nice and I did miss it initially as well. But Nautilus file manager has both SFTP and FTP support built into it. And if you want a dedicated client, I can recommend Terminus (but I am not a heavy user, rclone in terminal does most of my heavy lifting).

      Microsoft fired its entire QA team 10 years ago, and shifted the responsibility for testing onto developers. They also got rid of their dedicated hardware lab where software would be tested on many different hardware combinations.

      I have worked in two companies that made the same move of firing QA, and in both the quality of the released software took a marked dive. (In neither company did senior management admit that what everyone warned them would be a mistake was a mistake. Instead they blamed developers.)

      These days Microsoft’s testing team is whichever users receive each update first. They rely on users and telemetry to do what should be the job of dedicated testers.

      When I was still dual-booting Windows and Linux, I found that “raw disk” mode virtual machines worked wonders. I used VirtualBox, so you’d want a guide somewhat like this: https://superuser.com/questions/495025/use-physical-harddisk-in-virtual-box - other VM solutions are available, which don’t require you to accept an agreement with Oracle.

      Essentially, rather than setting aside a file on disk as your VM’s disk, you can set aside a whole existing disk. That can be a disk that already has Windows installed on it, it doesn’t erase what you have. Then you can start Windows in a VM and let it do its updates - since it can’t see the bootloader from within the VM, it can’t fuck it up. You can run any software that doesn’t have particularly high graphics requirement, too.

      I was also able to just “restart in Windows” if I wanted full performance for a game or something like that, but since Linux has gotten very good indeed at running games, that became less and less necessary until one day I just erased my Windows partition to recover the space.

              That depends, if you’re going to run a barebones W10 install with what amounts to a word processor I think 2GB should be enough. If you can run Chrome you can run a VM. 4GB if you’re feeling generous, that’s a fair compromise as compared to the disadvantages of dual booting.

                I remember trying to push the limits with a Windows 10 VM, and 2GB was the bare minimum;
                however, Windows loves to abuse virtual memory (basically using the main storage drive instead of RAM) and if that drive is a HDD the PC is little more than an IoT space heater.

                A relative of mine has a Windows 10 PC with 4GB of memory and it takes ~ 5 minutes to start Chrome after booting it up; it does have a lot of miscellaneous bloatware on it, though.

      Does that screenwriting software require a lot of performance? You might opt to install Windows into a virtual machine, as described here: https://www.windowscentral.com/how-setup-windows-10-virtual-machine-linux

      Essentially you’re using some software to emulate a computer inside your computer that can run any operating system you want. It doesn’t need to touch your actual operating system installation, you can treat it as just another program. For your use case that sounds appropriate; you occasionally need to run specific software that has low system requirements. This way you can do that without risking Microsoft borking your Linux machine any time it feels like it.

          That’s all fine and dandy but OP said they’re not very technical. Conceptually Virtualbox is a lot simpler to deal with. There’s a lot of advantages (philosophical and practical) to be had with a KVM or QEMU setup for sure, but if you want a simple to understand click-it-together setup then Virtualbox is better. If OP wants to graduate to a better setup then I hope they go for a good FOSS solution eventually but going straight for the deep end is rarely a good idea if you want people to understand what they’re doing.

        I’d imagine it requires about as much as a word processor, since that’s basically what it is. A word processor with a specialized template and some nifty autofill options. Again, dummy here. If I’m running a virtual machine, can I create a file in it that is saved to my actual machine, or would I need to, like, email it to myself using the virtual windows os?

      Do you know which bootloader you have? There are two popular ones in use currently, one called systemd boot, the other is called grub. From reading this post only grub seems to be affected. I don’t really know which one fedora defaults to at the moment, and it likely depends on what happened during the installation process as well.

        If they’re using Fedora, then it is highly likely that they are using GRUB as you have to very much go out of your way to utilize systemd-boot on Fedora the last time I checked.

        Don’t use Virtualbox as native libvirt will be faster and doesn’t involve any licensing.

          Depends if you care more about performance or ease of use. Based on the fact that OP hadn’t considered VM as a solution, I assume they aren’t super familiar with hypervisors.

            Virtualbox is a pain. Virtual manager is much easier and natively supported. You just click new and then follow the wizard

              That’s not at all the case in my experience. Sure virtual box modules can be harder to install, but libvirt has so many issues that the average user has no idea about. I’ve had networking issues, display issues, and so on. At one point it read the display scaling information and scaled down the VM display instead of scaling it up. Furthermore RedHat don’t even support virt manager anymore. They want you to use Cockpit. Honestly the all around best virtualization solution is probably VMWare or something like Gnome boxes or QuickEmu.

        I looked into it, but I can’t afford it out of pocket. The school pays for final draft, but won’t cover anything else :/ If I could, that would definitely be my go-to

          It’s free tho? Except for some minor limitations:

          “The free downloadable demonstration version of Fade In includes all key functionality except for online realtime collaboration, and will place a watermark on any printed/PDF output.”

          And there are ways around those

            Oh shit, this I did not know. I just Googled the price and I guess it only showed the paid version. Sweet! Thank you! If this works, I can officially uninstall Windows! That’s literally the last thing holding me to it. :D

              My pleasure. I will mention, that unless the author changed the program since last I used it, it also has a small popup every ten minutes or so, asking if you’d like to buy it. Remarkably, I didn’t find this terribly annoying, and forgot all about it until writing this comment - so don’t let that be a hindrance!

                So I just emailed my professor, and he says that I can use fade in if the formatting is the same as final draft, and I buy the license so there’s no watermark. Which sucks, but fuggit it it lets me keep using Linux. Do you know if the formatting is the same? This is only my second ever screenwriting class.

                  The watermark is only applied if something is printed directly from Fade In: export and print somewhere else and there should be no watermark. As for the formatting, I don’t recall - but I do know, that everything is configurable; so you can make the formatting the same, if it differs

      It looks like some GRUB versions are fixed, e.g. possibly in Ubuntu from 22.10. Dunno if Fedora has the fixed version. I’m facing the same with my Mint/Windows dual boot; considering not booting windows till I’m ready to upgrade Mint to 22.

      If you do get problems, it also looks like you can get around it by turning off secure boot until things are sorted.

      If you’re not an experienced Linux meddler I wouldn’t recommend changing your bootloader from the default given by your distribution, but I guess if this is widespread most distros will upgrade their bootlodladers soon to deal with it.

      Does your device have 16gb of ram? If so install Windows in Virtual manager with the guest addons. It will allow copy and paste along with lots of other features while keeping Windows in its own area.
