Windows 10: Prevent Windows from overwriting other OS's bootloader

Hi! Just as the title suggests, I'd like to prevent Windows from overwriting the bootloader.

Currently I have several operating systems (none of them being Windows) in my computer and all of them are managed by a single bootloader which installed on the SSD, but I'd like to know:


1) If I install Windows (again), is the same thing going to happen?

2) Is there any way to prevent Windows from 'telling' the motherboard to select Windows instead of my already selected bootloader?


My perfect scenario would be:

1) I install Windows on my hard drive

2) I can press F9 or the 'boot menu' key and then select the hard drive on which I installed Windows to boot it.

3) If don't press anything, the computer will boot to grub/systemd boot or whatever my bootloader is to let me choose which OS I want to boot.

And not this:

1) I install Windows on one of my hard drives

2) Windows automatically boots, overwriting the content of the current disk that contains the bootloader.


Thank you.

:)

vista bootloader problems

I've explained this so many times...

Basically if you use Vista and Linux, you are stuck with the Vista bootloader. It's only a bootloader. I had XP, Vista and Linux all running out of the Vista bootloader with no issues.

A Bootloader is nothing more than a tiny bit of software that allows you to choose which set of commands/OS to launch.

You want to use Ubuntu and Vista, you've gotta use the Vista bootloader.
