Question

running 2 OS.

Sep 13, 2017 4:29PM PDT

HY,, I have Win 10 running perfectly. I want to run some older games, so, with a other Hard drive, I installed Win 7. That seemed OK, ,,however,,the problem is, when I start up,, instead of running with Win 10, it runs with Win 7,, Win 7, is now showing as being the C drive, whereas before, Win 10 was the C drive, I tried to install the games on Win 7 when both drives were connected, but the games wud only go to Win 10.

Is there any way, that I can switch the C drive from Win 7 to Win 10, and also,, how can I load a game, or anything else,, to either drive? Surely there is some way of switching from one drive to the other ( Win 10 to Win 7,)when I want to install,, rather than all installs going to just the C drive. If the Main drive is C, then how can I load/install on E drive?

Thanks.

Hy James, Thanks for that,, and I will try it on start up. Will the same thing work when I am on, like now, or, only on start up? I have disconnected the Sata lead from the Win 7,, which is making Win 10 the C drive, and I am hoping, when I connect the Win 7, that will probly be a D drive, or something like that, n not the C drive.

Thanks for yur help,,greatly appreciated.

Some programs in their installation program have the option to install on another drive than the Windows you run is installed on. Others don't. If there no such option when you install it, it isn't possible.

But it being installed on drive X, doesn't necessarily mean that you can't run it after booting from drive Y, even if drive X and drive Y have different versions of Windows. That depends on the program. You only know if you try.
If after installing on the Windows 10 disk, you can't run it from Windows 10 (because it's incompatible, even in compatibility mode) and you can't run it from Windows 7 (because it's on the other disk), you'll have to boot into Windows 7 both for installing the game and for running it.
