I have 16 and I don't know anything about this, I just want to play video games and stuff, and install a "new" HDD

I had an old PC with Windows Vista, I didn't use it since 2013, cause it doesn't work anymore, so a few days ago I took the HDD from my old computer, but I know that the old HDD has an OS installed.

I was reading a lot about that, but I can't understand anything! :( I just want to know if you can give me some tips and recommendations before set up the old HDD because I have another one with Windows 10, I don't want to have problems, does my old HDD (Windows Vista OS) will interfere with my new HDD (Windows 10 OS) ?

It shouldn't. Your Windows 10 HDD is most likely set as the default boot drive in the BIOS (the drive in which your computers firmware will automatically look for an operating system to start) and your older Vista drive should just appear as a data/storage drive. Now saying that there could be problems but most likely not.

If you are looking to use that old HDD to store games on then I really suggest formatting it. This will delete all the data off that drive (so if you want to save anything youll need to move that data to your Windows 10 drive) and give you a fresh start.

Again this process will delete all data off whichever drive you choose.

with the OSs on separate drives you’ll be using the BIOS to select which one you want to boot. That means if you boot to one and decide you wan to use the other you’ll need to reboot, use whatever F key accesses the BIOS, access the boot menu, switch the primary boot device, save and exit. When you reboot the OS loads

that’s the basic answer on “how do I do it”. As for not wanting problems - you’ll have them. One example is you’ll need to install correct drivers on each OS.

you typically have a dual boot to take advantage of features and benefits specific to each OS, or tinker with an unfamiliar OS, so you’re not really getting either with two versions of Windows. But it’s good practice for when you want to try Linux or another very different OS.

Install the other HDD but it wasn’t installed on the machine in which it will now live so you’ll need to do some work, particularly with drivers, as for wanting an OS that won’t interfere with your Win 10 install...no OS would. They’ll be like polar bears and penguins in the wild and never see each other or know the other exists.

It won't mess with your current Win 10 install.
But also, it probably won't boot up in the new hardware.
And in the unlikely event it does boot up, the license will deactivate itself in 30 days.
