One thing many people do is make systems that will boot more than one choice of operating systems. This little article is a new and better way to do this. Often we have to fix the multi boot systems because an update changed something and damaged our grub configuration. Windows is especially good at doing this. So here is the best way to do this that allows you do make a multiboot system without having to do anything to grub or play with configurations.
This can only be done in a system that can accept more than one drive and an expansion card.
What you will need.
1.. One hard drive for each Operating System you want to install. (M.2 chips are not supported for this, must be SATA Drive)
2.. purchase one of these items.

https://www.amazon.com/gp/product/B07ZVTZVYD used for half height slots and supports up to 3 drives.
Install the board into the computer and it will control the power to each hard drive via a button on the back of the card / computer. You simply turn on the drives you want to use and turn off the ones you do not. You may set a boot order in bios still and I suggest you set a linux drive as the 1st boot and windows drives as the last ones. Reason for this is if you leave windows drives turned on along with linux drives, you will boot to linux which allows linux to access the windows drives. Windows can not see linux drives so it is pointless to boot windows and leave linux on. However with linux drives as boot priority in BIOS you will be able to access the windows drives from linux by leaving them turned on along with linux.
When installing the OS on each drive make sure it is the only one turned on. This will limit the OS to only that drive and will not try to do anything fancy with other drives. This separation also keeps all updates especially windows updates from affecting anything other than the drive they are on. That means no problems with grub or anything else as each OS is physically separated.
Obviously you choose the boot drive before turning on the system power, you can't hot swap and choose.
This configuration will remain in effect regardless of changes to any of the operating systems. This keeps your configuration safe and stable.
I have a triple boot with windows 7 windows 10 and Linux Fedora. No issues with updates or any other problems. I select what I need to use and everything is stable. Since I do not trust windows online I can download things in linux and send the download directly to the windows drive to install next time I boot on that drive.
