Ive literally never heard of that. Windows can overwrite grub/your bootloader though (easy fix, just boot into a live usb and reinstall grub).
If Linux eats your Windows install that's a serious bug. That means it's overwritten data on a drive that's not even mounted, without you directing it to do so.
Disclaimer: I'm not knowledgeable about the "under the hood" things on Linux OR Windows. I've just heard it can happen and really don't want that for myself.
