Need help to PROPERLY install dual boot: Windows 10 & Windows 10

You see the Indentifier field right below the Windows Boot Loader headings? That's what goes in the {} - whatever that identifier is will be the section that you are changing. It might be {default}, it might be {current}-which will always be the OS you are currently booted into- or if the section is neither the default nor the current OS, it might have a long string of characters making up a GUID - cut and paste that to make it easier.

Here's mine:

Code:

C:\Windows\system32>bcdedit

If I wanted to change Windows 7 Pro, for example, the command would be:
bcdedit /set {ec06c168-caf8-11e7-b1ac-10c37ba1c52b} description "Windows 10 Professional"

If I wanted to change Windows 10 Pro, the command would be:
bcdedit /set {current} description "Windows 10 Professional"

Still having a problem with the syntax:

If you are actually booted into Windows 10 Old the command would be:

bcdedit /set {current} description "Windows 10 OLD"

Finally getting there!

I finally got it! Uh-Oh, I lost it. I'll blame a bad headache. I want to change the description of my new Windows 10 OS to "Windows 10 Pro New" Please tell me the exact command to do this. Then, I'd like to switch the default boot order so that the Old version is the default (right now, the new version is the default). How do I do this?

Boot into the new Windows 10. When booted into the new Windows 10, it will be the current OS. So the command would be:
bcdedit /set {current} description "Windows 10 Pro New"

To change the default, run MSCONFIG - go to the boot tab. You can change the default OS there.

Next, I'll want to begin loading my software into the New OS. To avoid getting stuck with a bad app installation, I could use System Restore and/or an incremental Macrium Reflect image. What would you suggest as a protocol?

Also, what software would you recommend I install first (like Kaspersky, etc.)

Thanks, Commander!

I would recommend you do both - built-in Windows restore points and Macrium Reflect backups. The very first thing I would do in both operating systems is in a Command Prompt (Admin) run:
powercfg -h off

That turns off hibernation and fast startup, both of which can interfere with dual booting. I would not install any extra anti-malware/antivirus programs.

Well, Commander, I'm glad to find out that I'm not crazy. I've been entering that command and checking the syntax very carefully and am convinced that I'm typing it correctly. The difference is that, in my new version of Windows 10, I don't see Command Prompt (Admin). Instead, I see Power Shell (Admin) - which is what I am using. It doesn't like the parameter "/set". I don't know how to solve this problem.

If you, like me, never use powershell, then right click on a blank section of the task bar and choose Task Bar Settings and set the highlighted setting to off:
