More explanation:

When a Linux systerm is being installed, it looks around to see what 
other operating systems are already installed and adds them to the boot 
menu that will be created in Linux
Windows doesn't do this while it is being installed. That's why you have 
to install Windows first. Windows is unaware that there's another 
operating system if Linux is already installed.

Let's say you're installing 3 different Linux systems after you've 
installed Windows.

you already have Windows installed, there is no special boot menu.
Then:
when you install Linux #1, Linux #1's boot menu will include
Windows and Linux #1
When you install Linux #2, Linux #2's boot menu will include
Windows, Linux #1, and Linux #2
When you install Linux #3, Linux #3's boot menu will include
Windows, Linux #1, Linux #2 and Linux #3.

The default menu is that of the last Linux that was installed.

It is possible to copy a boot menu from one Linux system to another, if 
you prefer the style of one the Linux's system boot

I have 7 different Linux system (three UBUNTUs) installed but use #1's 
Ubuntu boot system. This required copying boot data from the other 
systems to #1's boot menu.
