2 hard drives

[Michael_334]

Is there a way to boot into windows 7 hard drive and then go into windows ten on the other hard drive. My one (main) drive will not let me boot ten from it but I can boot 7 on other. I want to use the ten interface

u cannot go into one version of windows from another version unless its a vm...better reinstall the windows 10 on a seperate drive/partition...

Yea unless you use something like Oracle Virtual Box you have to reboot to access each OS. If you DON"T need them at the same exact time it is better if they are installed on their own drive / partition (Install windows 7 first THEN windows 10). If you need both, download Virtual Box, it is free, and install a version of windows on that.
