It is a time for a single linux boot.
I never did dual boot. The first time moving from windows 2000 to Linux, my hard drive was only 2 GB and I couldn’t fit both of the OS:es on it, so I nuked the windows one.
At one point my 1GB disk was the “big one” in the dorm. It was the windows share of some random media. I had room for the whole 40MB videos “Jesus vs Frosty” (The Spirit of Christmas) and “Jesus vs Santa Claus”. It was before South Park became an actual show, but people watched those 100’s of times off my hard drive.
When I bought a 3GB from Fry’s it was an open question how we’d fill it. Of course, that was just as the mp3 codec started to gain traction… Problem solved.
I put windows in the shame box (VM).
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.
God, I’d have a back up in case I went full office space.
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!
This has been my solution for a long time.
If you need to dual boot, be sure to use separate EFI partitions for windows and Linux, separate drives if possible. Windows has done this far too many times.
Just remove Windows. One problem less on the list.
and unplug your linux drive when booting windows, just in case
So they were trying to patch systems that use GRUB for Windows-only installs? What a load of BS. Why would anybody install GRUB to boot only Windows with that? Or am I overlooking something?
Furthermore, if GRUB has a security issue, they should’ve contributed a patch at the source instead of patching it themselves somehow. I’m a bit stunned at the audacity of touching unmounted filesystems in an OS patch. Good thing Windows still doesn’t include EXT4 and BTRFS drivers because they might start messing with unencrypted Linux system drives at this rate

What is that latter fallback called? I set up my boot manually using an EFI stub last time I installed arch but wasn’t aware of any fallback bootloader

Thanks for the detailed explanation, makes a lot of sense! I guess what I did was set up a UEFI entry that specifies the location of the Linux kernel without any intermediate bootloader. Pretty sure I didn’t set the fallback, so I’m guessing that’s still owned by windows.

I agree they should have sent a patch to the grub source, but keep in mind big software companies like microsoft, Verizon, … do not normally allow their product teams to send a patch or PR to open source projects. This is because in their contract it states that all code written on and during company times is owned by the company. 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.
This changes when the team explicitly works on the foss product/project like the ms wsl team or the team working on linux supporting azure hardware, but that is an exception. I do not believe the microsoft kernel/bootloader team is allowed to send patches to grub.Its a terrible thing, and it shouldnt be, but thats the fact of the world atm.
What? Microsoft have written and released and contributed to many open source projects - they created vscode for one. They are even one of the top contributors to the Linux kernel.
Yes, but not all devs within microsoft are allowed to work on non-ms foss projects. I assume wsl devs are allowed to send stuff to linux but visual studio devs probably are not.
The wrote and released VS Code - a completely opensource development environment. If they wanted to patch Grub I bet they could have found the permissions internally to do that. Microsoft is a lot more open to OSS contributions then they were in the past.
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 vscodeSure, my bad. But it does not change my point. They have released stuff as opensource even if not all of it. Which means they can if they want to.
I know, hence why i said youre not wrong but the example was wrong :p
Also, its more complex than that. Some teams can, some cant. And if they can it all depends on what project or context. The business world isnt that cut and dry hehe
No surprises there, just the usual shitSo, 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.
FWIW, I’m dual-booting windows and mint atm. Separate drives, but just one EFI partition, and this update hasn’t borked things for me.
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.
I had the intention of reinstalling my windows because it was like from back when win10 was new and the winsxs folder was so big that a 100GB partition was not enough for just windows with all the 3rd party programs installed on another partition… but I noticed that all my games run on Linux so I ended up wiping the 100GB nvme windows partition and moving my dual boot Linux there. I’ve been without windows for a couple of months now and I haven’t really missed it.
This is a regular occurrence and honestly we need to stop recommending dual boot. Use separate drives if you need to, but sharing the same drive is destined to brick something
But having 2 drives does not solve the boot loading issue, I mean, even if you have two drives, you still have only one bootloader, not?
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.
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.
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?
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.
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.
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.
The boot entries live in firmware yes, efibootmgr can create and remove them. The are pointers to the bootloader. Many systems can boot from the disk itself without the entry, the entry just makes it pretty (“Fedora” instead of NVME1).
I’m not exactly sure what you’re suggesting. Isn’t that more or less what I just said?
Somewhat. One, a system can be bootable without the entries because they are just pointers to the actual bootloader, 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, they’re just saying “if I click Fedora load the shim from the EFI system partition on disk 1”.
This is very different than the old world where windows would delete your bootloader entirely and the MBR couldn’t be easily explored. 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, although it didn’t touch the shim itself).
The initial comment was about the bootloader and really only applies to MBR partitions.
I don’t think dual boot has ever been a good solution (unless you also run one or both of the OS’s under the other in a VM).
Like, if you are unsure about linux, trying it out, learning, whatever, you can just boot a live"cd", or maybe install it on an external (flash) drive.
If you are kinda sure you want to switch, just nuke Windows; it’s easier to switch that way than to have everything on two systems, having to switch.
That is until you want to switch and use mostly linux, but you have friends who want to play one of those few games that only works on windows
The second windows isnt the only option for “all games without any effort”, it will be dead.
Well i believe it already is for the majority of games, though I don’t game anymore so I don’t know, proton wasnt 100% a year or two back
I’ve been on Steam+Proton for more than 3 years now. So many many games are now supported. It is usually the DRM kernel anti-cheats that are Windoxez only tend to be the broken ones. I dont buy or care about games that run anti-cheat in Windoze kernel.
I literally got this error using a bootable SSD with Ubuntu Mate on it. Separate drives aren’t immune to the issue.
This isn’t true if you have a bootloader on each drive, which, I think, is what the we’re talking about.
Classic
That’s what happens when you don’t keep windows locked inside a virtual machine.
Microsoft breaks bootloader and nixes Linux partition
Microsoft: “patch seems to be working as intended”
Doesn’t Windows break dual booting semi-regularly? I’ve always avoided it as I’ve had friends get burned by this in the past. I guess I just keep different OSes on different drives, but that obviously isn’t feasible for everyone.
I know that used to be the case. It’s why I stopped trying to use a dual-booting system and instead just installed windows in Virtualbox.
It’s a lot better in uefi, MBR dual booting was always sort of hacky.
I have dualboot set-up on my MacBook and have no. But it is a long time ago, since I last started macOS and my Mac would not get new macOS updates anyway😂 that was the reason to install Linux in the first place 😝
I guess I switch to single boot Fedora Silverblue just in time
Microsoft! You missed your last chance to stay on my computers with your os. Take care, so long and thanks for all the cons.
The only way to fix your computer is to uninstall all spyware like Windows
