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

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.

I actually had the issue of Windows 10 deleting its OWN partitions. computer started running funny, then it BSODed and then would only boot to a flashing cursor. Booted into repair only to find that my system drive was reporting as 100% available. not even the Windows 10 system partitions were present. nothing could read any semblance of a partition table from the drive to recover any of my data.

The EULA's binding arbitration has already been shown to be a paper tiger. It is not being enforced by the courts.

What if it were a disk failure instead? Cryptolocker? Inadvertent keystroke, or even cat on the keyboard?

The partition getting deleted is obviously Microsoft's fault. The fact that it caused permanent loss of important data however is more the user's fault. If it's important it needs to be on at least two different disks, and the further separated those disks are physically the better.

Just because someone is the victim doesn't make their actions or lack thereof perfect. If you're not backing up your important data you're guaranteeing that many possible problems which would otherwise be an inconvenience immediately get bumped up to disaster.
