Question: Hi there,
I have a pc with a HDD of 1 tb with windows 10 installed, I would like to add a second hard drive HDD with 500gb space from my old PC but my second hard drive already has windows 7 installed in it and some important data.
I don’t want to lose my data in the second hard drive. Is there a way I can install my second hard drive to my PC without losing its data.
Answer:Connect your 500GB drive to a free sata port with sata data cable and to PSU with sata power cable.
Make sure boot order in BIOS is correct.
Boot into windows 10.
That’s it.
