How do I prevent Windows Update from breaking my dual boot BEFORE it happens? (self.linuxquestions)

Now that we're a week in and most people have probably repaired their PCs from the shitty Windows Update breaking GRUB I have some question.

I have a dual boot as well and thought I was safe, as I installed my Linux Mint on an independent disk. My friend laughed and told me that won't protect me.

I logged into Windows some days ago as I had to write a document in MS Word for university and the windows update told me it was ready with a very threatening red dot in the tray. I expected it to take control over my PC and to reboot 10 times, do some typical Windows stuff, but nothing happened.

Now I have this update waiting and I am scared my Linux will break. I know there are fixes out there, but is there a way to prevent it BEFORE it happens? Can I somehow upgrade the vulnerable GRUB version?

Thanks a lot for your help my fellow penguin fans.

You could build yourself a bootloader-on-USB-thumbdrive. You could then either just decide that's your primary bootloader and unplug it every time you boot into Windows before it gets far enough into Windows to break your bootloader or just use it as a recovery device to get back into Linux and get Linux to fix your bootloader as soon as you've booted it. (The former approach is more in line with your "before it happens" requirement than the latter.)
