Windows 10: W7 pro & W10 dual boot problem

I want to Dual Boot my existing W7 pro with W10 pro as in Dual Boot Tutorial by Brink. I made W10 Installation USB removed fast boot & secure boot and installed W10. I have W7 (C drive) on a 500gb SSD and installed a new 500gb SSD for W10 (D drive) I installed W10 on the D drive no problem. Just as shown in the tutorial by Brink, How to Clean Install Windows 10. Everything worked fine except no Dual boot.

On reviewing my steps, I disconnected the C drive so that the W10 install would not install over my W7 pro. My plan was to run and evaluate W10 on a separate drive, adding Applications ie Quick Books, FedEx ship manager one at a time to be sure all worked well. If all OK then I would do another W10 upgrade over my W7.

1. But, I have no dual boot, I think maybe disconnecting the C Drive was wrong, I shot myself in the foot. Do I have to uninstall W10 and reinstall with my C Drive connected? If so, will W10 install on the C drive over W7, that would be a problem. Does the W10 install process allow me to select the installation location.

2. During the Install process, I was asked to enter my Product code I entered the code from my W7 Pro package but got an error message, product code was incorrect. I then checked the later box but I will have to solve this problem. The code I entered was from my W7 pro package?? what to do?

Thank You for any comments

Creating Dual Boot of Windows 7 and WIndows 10

Original Title: W7 and W10 together?

Since WMC is missing in W10, can I keep W7 and install W10 for dual boot?

 

Age of Empires 2 The Age of Kings won't work on Win 10.

I have a dual-boot machine with XP-32 (installed first) and W10 (former W7-64). So it is possible to have a dual-boot.

To do it : you have to install XP first, then W7. W7 "installs" a dual-boot menu. Thus you can choose the os you want to start with.

Then you upgrade W7 to W10. You still have the os menu choice at startup.
