Microsoft has issued a security update that has broken dual-boot Linux and Windows machines. The update wasn’t supposed to reach dual-boot PCs.Tom Warren (The Verge)
This means that it is impossible for them to make a patch or PR because it would conflict with the projects licence and fact its open source.
That's not how it works. It just means the company owns the code for all intents and purposes, which also means that if they tell you that you can release it under a FOSS license / contribute to someone else's project, you can absolutely do that (they effectively grant you the license to use "their" code that you wrote under a FOSS license somewhere else).
They can forbid you to work on opensource stuff while being in free time? I mean, I understand that you are not allowed to generate open code that utilises private know how of the company you work for. But not working on Linux in free time seems very strange to me 😮

I keep Linux and windows on separate disks, grub or windows boot manager don't know about each other.
I have the Linux disk as the primary boot, if I need to boot into windows i use the bios boot selection screen.
It's a bit of a pain at times(have to mash F12 to get the bios boot menu) bit it's less of a headache than trying to fix grub
Your assessment of probability is speculation
It is, but anecdote is insufficient to counter it.
No. You can have more than one EFI system partition with separate bootloaders on each drive and set their boot order in the BIOS, just like booting from USB or anything else.
This is also possible with just one drive. The efi boot entries for each OS are stored separately in the efi system partition.
Legit have never had an issue with multi boot and windows like ever, tbf I don't go into windows that frequently anymore but it's never given me grief in at least a decade. I know my experience isn't universal though, so sorry to anyone who does have boot issues after windows updates.
In the worst case, could use bcdedit and use the windows boot loader (tbh I have no idea if that works here, but could be worth a try)
Reference article for the bcdedit command, which creates new stores, modify existing stores, and add boot menu parameters.learn.microsoft.com
even if you have two drives, you still have only one bootloader, not?
The idea is to have completely separate boot and OS drives. You select which one you want to boot through the BIOS boot selection (ie. pressing F10 or F11 at the BIOS screen).
This functionally makes each OS "unaware" of the other one.
I'm not saying you're lying, but you said
do not allow software developers to send a patch or PR to open source projects.
But this sentence in particular was misleading. Maybe you specifically did not have the right to do so, but in the Linux and BSD codebases there are a lot of @microsoft @netflix @oracle contributions, so at least there is someone in those companies authorized to do so
Yeah if you write proprietary code and then work on a similar project in your spare time, your company might sue you because you're likely reusing code you've seen or written at work.
For example Windows developers are forbidden from working on ReactOS
Fair, and ill edit my post accordingly!
There are teams that are allowed, and within those companies are teams that are directly related to foss projects because those companies are in the foundation or supports of the foundation. However, thats doesnt mean every (product) team in the company is allowed to or that they can do or change whatever they like. Its a complex mess
Unfortunately it really doesn’t. And it’s actually Linux that’s the bigger problem: whenever it decides to updates GRUB it looks for OSes on all of your drives to make grub entries for them. It also doesn’t necessarily modify the version of grub on the booted drive.
Yes I’m sure there’s a way to manually configure everything perfectly but my goal is a setup where I don’t have to constantly manually fix things.
EFI can also live in firmware memory.
You can pull the linux drive, boot from the windows drive, and if one of the firmware updates was for efi, windows will trash the entry for your Linux disk.
This has happened for me many times, I had to use a grub rescue disk to rebuild the efi table.
Oh you sweet sweet summer boy....
We're talking Microsoft here, they'll make sure they're aware and they'll make sure to f you over because Microsoft
Remove your Microsoft installation, done.
Yes but...
But what? This is Microsoft, they fucked it up so many times that it's either incompetence or sabotage, and knowing Microsoft, it's probably both.
This is the same company that invented millions to sabotage Linux through the legal system (hello sco), and the same company that in purpose left gaping security holes open as to not lose any money, causing China to hack the US government through said holes.
Then we decide that just that money isn't enough so we'll spy on you at every step of the way, we will force feed you ads, and we'll use you to train our shitty AI
Frack Microsoft, frack any and all of their software.
Really depends on the virtualization technology, hardware, configuration and game. Not a gamer myself.
Gaming on linux has come a long way in recent years though, in no small part thanks to Steam.
While I generally agree with that, that's not what seems to be happening here. What seems to be happening is that anyone who boots Windows via grub is getting grub itself overwritten.
When you install Linux, boot loaders like grub generally are smart and try to be helpful by scanning all available OSes and provide a boot menu entry for those. This is generally to help new users who install a dual-boot system and help them not think that "Linux erased Windows" when they see the new grub boot loader.
When you boot Windows from grub, Windows treats the drive with grub (where it booted from) as the boot drive. But if you tell your BIOS to boot the Windows drive, then grub won't be invoked and Windows will boot seeing it's own drive as the boot drive.
This is mostly an assumption as this hasn't happened to me and details are still a bit scarce.
If you install each OS with it's own drive as the boot device, then you won't see this issue.
Unless you boot Windows via the grub boot menu. If you do that then Windows will see that drive as the boot device.
If you select the OS by using the BIOS boot selection then you won't see this issue.
I was bitten by Windows doing exactly this almost 15 years ago. Since that day if I ever had a need for dual-boot (even if running different distros) each OS will get it's own dedicated drive, and I select what I want to boot through the BBS (BIOS Boot Selection). It's usually invoked with F10 or F11 (but could be a different key combo.
I did that and a Windows update nuked Linux from the BIOS boot loader a few weeks ago.
The only safe option is to have completely separate machines. Thankfully with the rise of ridiculously powerful minipcs that's easier than ever.
My install does not seem to do this. I removed the windows drive when installing Linux on a new drive. Put both drives in and select which one to boot in the bios. Its been that way for about a year and, so far, grub updates have never noticed the windows install nor added to grub.
That's with bazzite, can't speak for any other distro as that is the only dual-boot machine I own. Bazzite does mention they do not recommend traditional dual boot with the boot loader and recommend the bios method so maybe they have something changed to avoid that?
I recently discovered that Rufus has an option to set up a Windows ISO as "Windows on the go" so I dug out an old 500Gb SSD that had a USB adapter with it and installed Windows on that. So now instead of dual booting I can just hit F12 and boot from USB on the rare occasions when I need to run something in Windows.
It's also quite satisfying to be able to physically remove Windows and shove it into a drawer when it goes full Windows too lol.
Rufus: Create bootable USB drives the easy wayrufus.ie
I pretty much did just go full office space on it lol. Here's a fun thing I just learned:
Windows 11 apparently defaults to a tiny fraction of space for system restore points, and if it runs out of space it just deletes the old ones without asking or telling you. Because it defaults to a tiny amount of space, it apparently only ever keeps one system restore point on hand.
This means I made a manual one on a clean install when I'd got my settings sorted, so I can hop back to that when Windows inevitably fucks up. But because it's Windows, what it did was apply a big update, fuck it up, then save that fuck up as the only restore point.
I restored it anyway just to see what would happen, and that broke even more stuff. Back in the drawer!
I should have been more clear,
Assuming dev/sda is Linux and dev/sdb is Windows, I have grub on sda and Windows bootloader on sdb. I use a hotkey at boot to tell the bios which drive to boot from.
Theoretically windows thinks it's the only OS unless it's scoping out that second hard disk.
If you've recently updated Windows and found your system no longer dual boots, here's why and what you can do about it.Jack Wallen (ZDNET)
So, excusing my ignorance as a fairly recent Linux convert, what does this mean for my dual boot system?
I haven’t booted windows for weeks and am pretty sure there have been no updates since it was freshly reinstalled (maybe 6 months ago) as a dual boot with Debian.
Is this only a problem if I allow Windows to update?
Are Microsoft likely to fix the issue in a subsequent release?
Yes, you don't have to worry as long as you don't boot up windows and let it install the update.
This is not the first time they break dual boots by touching the partitions, but this is the first time they deliberately break it (that I know of).
I always had windows on its own drive because of that. If you don't use windows a lot then I would suggest to do the same. You have to change to windows through bios but it isn't that much more work.
Thanks for the reply, and good to know!
I think I’ll blow away the windows install on this machine completely.
I still have another pc for some audio tools that don’t run under Linux, but this machine is my daily driver now and I couldn’t be happier.
Not saying youre wrong, but you took the wrong project as an example hehe.
Visual code is not open source. Its core is, but visual code isnt.
The difference is what visual code ships with, on top of its core.
Its like saying chrome == chromium ( it isnt ).
Visual code comes with a lot of features, addins and other stuff that isnt in the core.
.net debugger for example, is not found in vscodium ( build of the vscode core ). And there is more stuff i cant think of now but have come across.
Source: been using vscodium for a few months instead of vscode
Somewhat. One, a system can be bootable without the entries, so even if windows does the stupid and deletes them it isn’t the end of the world. It does depend on your specific firmware though.
Also two, you can write them again with a single line in efibootmgr.
This is very different than the old world where windows would delete your bootloader entirely. They live in the efi system partition instead - or at least the shim does- and typically every OS leaves the other ones alone (even Windows, except in this case).
