From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

While I generally agree with that, that's not what seems to be happening here. What seems to be happening is that anyone who boots Windows via grub is getting grub itself overwritten.

When you install Linux, boot loaders like grub generally are smart and try to be helpful by scanning all available OSes and provide a boot menu entry for those. This is generally to help new users who install a dual-boot system and help them not think that "Linux erased Windows" when they see the new grub boot loader.

When you boot Windows from grub, Windows treats the drive with grub (where it booted from) as the boot drive. But if you tell your BIOS to boot the Windows drive, then grub won't be invoked and Windows will boot seeing it's own drive as the boot drive.

This is mostly an assumption as this hasn't happened to me and details are still a bit scarce.
