Windows 10: Dual booting Windows 10 on OEM install, drive not found

I have a Dell laptop with Windows 10 Home installed. I also have a Windows 10 Pro license with the USB stick provided. I'm trying to dual boot Windows Home and a new Windows Pro install so I can configure the Windows Pro specifically for audio post production.


I have resized the C drive creating 200GB of unallocated space. When I reboot with the USB drive and start the Windows Pro install it doesn't see this partition, nor anything at all when using the Custom install option. Using shift F10 to open the terminal and run DISKPART no disks are listed when running 'list disk'.


The laptop is new. The Windows 10 Pro box is a few years old.


How can I get the Windows 10 Pro install to recognize the disk? Once installed will the install recognize the 2 installation and give me an OS choice on boot?

Dual Booting with Windows 8.1


The procedure below will allow you to boot Windows separately or in dual boot configuration.
Here's what I recommend to do:

1. Disconnect the drive containing Windows 8.1
2. Install Windows 10 with one drive connected.
3. After step 2, reconnect the drive containing Windows 8.1
4. Boot up Windows 8.1. Open disk management and take a note of the drive letter of Windows 10 OS.
   NOTE: if you boot up Windows 10, then take a note of Windows 8.1 drive letter
5. Open Admin command prompt and type: bcdboot X:\windows where X: is the drive letter of Windows 10 (Windows 8.1 if you boot from Windows 10 in step 4)
6. Reboot the PC. You should have a dual boot screen.

NOTE: To break off the dual boot setting, Win+R->msconfig->boot and delete the none default entry on the list.

 

Dual Booting 2 x Windows 10 OS Drives (Existing Installs)


It is uneccessary to do all of the above.

1. Boot up Windows 10
2. Open Disk Management and take a note of the drive letter of the other Windows 10
3. Open Admin Command Prompt and type: bcdboot X:\Windows where X is the drive letter noted in step 2
4. Reboot, you should have a dual boot menu.
