Linux MD raid had a spat of random issues were it appeared that multiple disks without a partition suddenly got partitioned (on a boot). And at least some of those people NEVER dual booted (so no windows). The leading theory was that a bios/EFI update decided that disks that it did not identify as having data needed to get "fixed" and have a GPT partition table on it. There were 3-4 different people that reported this in a 2-3 month window with none since then, with a wide variety of controllers, but a number of them started after firmware updates or motherboard replacements/upgrades. And I know enough "smart" developers that love to write code to "fix" things that they "know" are wrong and simply don't understand. I have also seen a software update "fix" (ie change) the partitioning because they decided the old way was wrong and did not consider there might be data on it.
