3 - Configure and Set Active Partition
A very common cause for error no such partition to show up is not having the correct partition set as active.

Step 4. Go to "Troubleshoot" > "Advanced Options" > "Command Prompt" to launch the CMD.
Step 5. Now, Type diskpart and hit the Enter. Type the following commands in order and hit enter afterward:
list disk: (this lists all hard drives in your computer)
select disk n: (n means the disk where Windows 10 is installed. Here you can choose disk 0 or any other disk where Windows 10 is installed)
list volume: (this list all volumes on system disk)
select volume n: (n refers to the number of system partition)
