How to change boot drive?

[Daniel 558]

I changed the boot drive from C to D (using EasyBCD) , now my pc won't boot.
How can I change the boot drive back to C?
I have access to Windows 10 recovery menu which has a command line prompt.
Thanks in advance.

Hi, I think this can be done with diskpart. See if this page helps:

If you can get back into Windows afterwards, you can then use Disk Management in Windows to assign drive letters if needed.
