Windows 10 Anniversary Update Borks Dual-Boot Partitions (omgubuntu.co.uk) 281

Posted by msmash from the case-of-mission-partition dept.
Windows 10 Anniversary Update may affect and even delete other partitions on the same disk, OMGUbuntu is reporting, citing several complaints by users. "Broken boot loaders on an update are one thing but losing data, even entire partitions?" asks the author. Microsoft-centric news blog WindowsReport is corroborating on the report, adding that in some cases, the new OS was not able to detect some partitions. It says (edited): Many users are reporting that some of their partitions disappeared after installing the Anniversary Update. Usually, it's the smallest partition that disappears, although we couldn't say for sure whether the partition is deleted or if Windows simply doesn't detect it. Some users are saying that the partition is not allocated, while others can detect it once they install third-party partition management applications.We have reached out to Microsoft for clarification, and will update the post when we hear back from them.

    As in, installing Windows after installing Linux will mess with the boot loader.

    Everyone running a dual boot system should already be aware of this since the recommendation is always to install Linux second.

    New major updates to Windows 10 are basically entirely new operating systems. They just make the process more transparent these days.

        The Win10 upgrader (from Win7) did exactly this to my Linux partitions.

        The upgrader needed a few hundred MB of space to create some sort of rescue partition. Rather than resize the 1TB NTFS primary partition at the front of the disk (of which 900GB were free) it decided that (because it didn't recognize the filesystem type in the partition) it was okay to _delete_ the first logical partition, resize the extended partition by a few hundred MB, and move the extended partition down. It then made another primary partition in front of the newly moved extended partition and formatted that primary partition with NTFS.

        I've _never_ had a Windows installer do so much damage. Overwriting the bootloader? Sure! That's shitty, but entirely reasonable. Deleting partitions that aren't FAT* or NTFS because you don't recognize what they are and -thus- assume that they're unused? That's _incredibly_ shitty.

        This is the kinder, more open-source friendly Microsoft, guys.

        I hope to hell that this Win10 update doesn't put me through this shit again. That wasn't a fun day.

    • Yup, that's been the case since at least the Windows 95 days.

    Back in the late 1990's I was dual booting Windows and Linux. A PC magazine had included a CD with an early version Red Hat Linux and ran a series of articles on the strange OS. Linux had no problems dealing with the Windows partitions.

    Move forward a bit to Windows XP and more dual booting.Commercial and free partition managers support Linux partitions. Windows would still screw with Linux partition, particularly when installing Windows, so having keeping each OS on a separate physical HDD became critical. That way you could unplug the Linux drive to protect it from MS incompetence. Amusingly, Linux could mount Windows partitions to transfer files over and I was able to install a driver on Windows that allowed Windows to mount Linux partitions, however, Windows XP had no native support for non-windows partitions. Linux proves to be more capable in key area than Windows but I'm still using WInXP as my main OS.

    Jump forward to Windows 7 and Linux dual booting. The situation has improved a bit because you could technically let Win7 manage booting mulitple OS but it still screws with Linux partitions and has no native support for Linux partition types. Linux still does a better job and I can go months without booting into Windows anyway. More commercial software supports Linux, including games, and the open source applications available have greatly improved to the point of being better than MS products. I really hated the ribbon interface nonsense in MS Office because it reduced my productivity, it was nearly a stupid as having some animated paperclip jumping around on your screen while you're trying to work...

    Windows 8 appears and I decided than if I'm ever forced to replace Win7 I'll just give up on dual booting and just stick with Linux full time. Windows 10 brings spyware and adware built into the OS, setting a new low for MS and having some very surprising side effects; friends, family and people barely know are wanting to know about Linux and how they can get away from Windows 10. There has never been a version of Windows that happily coexists with another OS, why would anyone be surprised that Win10 is breaking Linux dual boots? It is either intentionally evil or supreme incompetence; MS has a history of both.

    Single, basic bitches NTFS partition. Perfectly fine in Windows 7. Perfectly fine in Windows 10 before the rapeiversary update. Now inaccessible, showing as raw in disk management, and Windows is begging to format it.

    Worse than the "lol that's a perfectly fine external drive you've plugged in and it works fine, but u wanna scan and fix anyway?" shit because the data is actually inaccessible on Windows 10.

    • Reminds me of an issue I have with WDC 'advanced format' drives (4096 physical, 512 logical sector size) plugged into my cheapo' external usb adapter. It messes up and treats them as 4096/4096 (or 512/512?) devices, so all the sector offsets are counted wrong. But sector 0 still works and so the partition table can be read. The contents can be interpreted properly using a geom gnop sector size adapter device, if desperate.

    Unless you absolutely have to, do _not_ install Linux and Windows on the same physical hard drive. For many purposes (e.g. basic coding and web stuff) a lightweight Linux distro will run just fine off a USB memory stick (I use Ultra Fit's in either the 32GB or 64GB size). Then, if you are buying a laptop and you're a techie, get something where it is trivially easy to swap out either the hard drive (i.e. not Asus crap where you have to remove the keyboard to get at the hard drive), or the optical drive. For example, boot Windows of one hard drive, and stick another in the optical drive bay. If you have a desktop, you have room for more than one physical drive. This also means that, during critical stuff like OS installs, you can physically disconnect your Linux drive so that Windows cannot get at it. My favourite example of Redmond silliness involved Windows 2000 appearing to enumerate partitions one way in the partitioning part of setup, and another way for the formatting part. Basically, on my dual boot drive, Windows 2000 setup ended up formatting the wrong partition. I say it had cocked up when I noticed the size of the partition it was formatting: my shared data drive. By the time I had stopped the process, of course, the FATs were already overwritten.
