dual w7 w10 on 2 different drives

[craign924]

Hello support members,

i want to accomplish the task of dual booting w7 and w10 on 2 different drives.
i have read posts on how to do this but I do not understand why i would need to upgrade w7 to w10 and then revert it back to w7 which seems to be the general suggestions.

I have been using the drive with w7 on it for years, I would like to keep that untouched.

I want to purchase a copy of w10 pro OEM, and install it on the new drive. and have a choice
of what OS to boot into.

I need some advice.

Thank You,

Craig

Hi,

I dont think you need to upgrade to Win10 then revert back. The procedure is like this:
1- Install Windows 7 on Drive C (or any drive)
2- Install Win10 as a new installation (not upgrade) on Drive D

This way you should have 2 operating systems on your machine, so you can boot anyone you like. I never done it Win X with Win 10 but this is how I did it before.

Regards,

You already have a viable Win 7 running on a drive?
No problem.

Purchase Win 10

The only question is how you wish to 'choose' the OS to boot ito.

1. Choose via the BIOS boot menu.
For this, you disconnect ALL drives except the one where you want the Win 10.
In stall it
Once done, reconnect any other drives.
Upon boot up, you choose the OS and drive in the BIOS boot menu

2. Choose via a Windows boot menu
For this, you leave the Win 7 drive connected.
Install Win 10 on the other drive.
At bot up, you will be presented with a Windows style boot menu, giving you the option of which OS you want.


Either way works. I've used both.
