[SOLVED] Windows 10: Running two separate Win 10 installation on separate drives (Work/Gaming). How to do it best?

Apparently, my question is strange enough that there aren't any similar ones that don't involve a Windows/Ubuntu dual boot.
Incidentally, I wouldn't mind running linux on its own drive, but my question is not about that. I have several old laptops that run some kind of dual boot, I know how they work.

No, my question is: what is the best way to run, out of the same computer, two separate Cdrives, each with its own independent windows 10. One for work, one for Gaming.

As you can likely see from my signature, I have a fairly good windows workstation and I am in the market for a more modern Graphic card.

I would like to start gaming again though, and "Gaming" for me means Auto racing simulators and Flight Simulators. I have the racing seat, the manual shifter, 4 different wheels and some old Flight sim gear as well.

Here is the issue: My work windows install is geared toward working with a number of clients. For that reason I have to have Gdrive, MS Onedrive, Adobe Cloud, Dropbox and a plethora of other programs, as well as all sort of monitoring software, etc. etc. This means not only a bunch of processes running in the background, but also means notices from a half dozen services, interruptions, calls, etc.

Well, back when I was more involved in Racing and Flying Simulation I used a separate Windows profile I could setup differently from my working profile. It wasn't ideal but it was better than nothing.

This time I happen to have at least 3 SATA3 SSD slots that are not being used plus a PCI3 SSD slot that's empty.
It occurred to me that running a separate installation of windows just for gaming would make a heck of a lot more sense. In fact, I calculated I could run the OS and most of my games out of a 250GB SSD I have laying around and then use another 250GB SSD as a documents/files repository, cutting out even my 4 (3 internal, one external) document and backup drives.

In fact, if it works, I'll be happy to go out and buy a PCIe SSD just like the one my machine is running right now, put it in the other slot and run my Gaming Windows 10 out of that, using one of the 250GB SATA SSD out of the SATA port for anything that may not fit in the Cdrive, if that's even a concern. For instance, Microsoft Flight Sim is supposed to be huge. If my C drive is a bit tight, I could use one of my extra SSD just for it.
In Driving Sims Circuits can take a lot of physical space, again, I can put those in a separate SSD.

That way, my work computer is pretty much left out of the gaming business, my games should run pretty fast and the only thing they will really share will be a bunch of 4TB storage HD I won't be using while I am gaming.

1) Is there something that can help me make a choice between startup disks either before I shut off (like the macOs does) or that gives me a chance to choose the start up drive as soon as the computer restarts, defaults to my main Installation, but lets me choose another disk to start with without it being a hassle?
In other words, is there a way for me to say "Next restart, use the OS from this HD" or something similar enough?

2) Do I have to buy another copy of Windows 10? I would be only using one installation at a time on the same hardware. The ID should be the same. Anyway, do I have to buy a new Windows 10 or in my case one copy could be enough? I don't care either way, but if I can save $200 for Windows pro I'd be happier, or maybe I can run Windows Home for Gaming.

What say you? Can anyone help?
 
Solution
Disconnect all drive but the one that will be your game drive. Install windows 10, & drivers.
Shutdown and swap the game drive for the work drive.
install Windows & drivers.
Shutdown. Install all the drives.
Enter toe bios and set the drive that you will boot to most often as the Primary boot device.
When you want to boot the other drive, on the screen that tells you ro press Del to enter Setup/bios there is another option to boot from another drive. Press that F-key and select the drive you want to boot from.
If the drives are the same model, you might have to try a few time to get used to which drive is which.
Win7, Win7 backup, Win10 & Ubuntu here all on separate drives in my pc.

I'm not sure if you will need to be in Legacy mode...

I'm not sure if you will need to be in Legacy mode in the bios since I run raid and legacy is required.

Thank you very much. It's essentially the process I did when I rebuilt by rig a few months ago (back when we wore masks for halloween) but I am pretty sure that without your reminder I would have screwed that up.

Another question that occurred to me: I read someplace that partitioning SSDs is not such a good idea. Any guidance in that regard?

My ultimate configuration will be 3 x Win 10 + Linux.
Work Windows
Gaming Windows
Music Production WIndows (Although, Gaming and Music Production have such similar requirement it may not be worth it to have a triple boot).
I also wanted to build a Hackintosh at some point. Yes, I know that the Hackintosh is going the way of the Dodo, but I am still using a Mac Mini with High Sierra and I really like Garageband and Logic Pro as a "canvas" for ideas, even though I complete my songs on Windows, sometimes restarting from scratch.

Anyway, since I have an extra slot on my motherboard, I will buy another 500GB or even a 1000GB SSD and mount it on the MOBO. I'll save my 2.5" form factor ssd for Linux.

Thank you again
 
"partitioning" is not so much a "bad idea", as it is "mostly useless".
Whether it be solid state or spinning drives.

Partitions on a spinning drive are physical delineations. Outer portion, inner portion, etc.

Partitions on an SSD are merely logical representations. The software (Windows/Linux/whatever) shows you the different partitions, but the drive and its firmware puts the data wherever it chooses. And shuffles it around for wear leveling.
