[Amina Alomari]

Hello
Have a nice day.

I have a costum built pc .. with the following specs
Cpu core i7 7700
16 gb ram
Nvidia gtx 1070
2 terra hdd
Case ATX K550
Motheboard asus strix h270f gaming
Power supply xfx p1 600b xtfr

The windows on my hdd now is windows 7 x64
I am wondering if i can install a second hdd in my case and install windows 10 on it?
Would that work? And would my new hdd affect the old one in any way?
And if it works .. any tips on how to do it basically? Or how to start?

Thanks ahead

You can do what you plan on doing. I had a dual boot system with Win 7 and Win 10.

The tutorial from the Windows 10 Help Forums may help with the installation.

You can have more than one OS on a single disk, but if you do something wrong you loose everything.
My suggestion is to install on another drive (as you planed), so if something goes wrong, you just wasted time.
Very important: Disconnect your Win 7 disk from the MB leaving on only the disk you intend to install win 10. After installation you may attach the win 7 disk back to the MB.
