I'm running 2 OS's on my computer. Win 10 as my default and win 7. i have a 128GB ssd for my win 10 and a 2TB HDD for storage. I hooked up a 500GB HDD and installed win 7 onto that one. Is it possible to have it where my Win 10 wont detect the HDD that my win 7 is on; and when im on my win 7 drive, have it not detect either of the ssd or the 2tb. Making them shut off from each other. My motherboard is an Asus z97-e. The only way i can currently think of this is to manually turn off the sata port through the bios every time i turn it on. but i would rather see if there was an options to just completely separate them without having to go through the bios every time.
