Dual Boot on one PC, 2 HDD's, 2 Systems.. win 7 and win 10

[Wolfgang_1]

I had two PC's one HP and one Gateway... one system broke. Bummer, now I try to run the second hard drive with win 10 on the other system with win 7.
Connected over Sata cables, the original HDD stayed connected on Sata 1 and the sec HDD on Sata 3. After booting up the pc I’m in win 7, I have access to the files on the 2 HDD but I'd like to be able to boot into win 10 to run the system. All my data, emails, logins are on the sec HDD. I tried it in the boot Menu to boot from the sec Raid but it won’t let me. Any suggestions or solutions?

I'm not sure what you mean by "boot from the sec Raid". If your Win 10 HDD is just a single HDD you can download easyBCD to edit your boot menu and add Windows 10 as a dual boot option.

Thank you I'll give it a try with easyBCD. I'm not an expert on any of this stuff.
