Windows 10: Dual Boot Windows 10 On Different Drives

I would just like to get confirmation on whether it is possible or not to dual boot two Windows 10 installations on separate drives with the same boot manager.


For information I have tried using bcdedit and EasyBCD, and it works flawlessly on two partitions on thesame drive, however whenever I try to set it up ontwo different drives Windows gives me the following error when trying to start the installation on the 2nd drive


Recovery

Your PC/Device needs to be repaired


The application or operating system couldn't be loaded because a required file is missing or contains errors.


File: \windows\system32\winload.efi


Error code: 0xc000000e


Now, I know that the file exists, that it isn't corrupt and that the disk is bootable because removing any disk lets me boot the other without issue.


Seems to be like there is a limitation with Windows Boot Manager. Can anyone verify this?

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.
