Changing the EFI (Boot) disk that starts Windows.


Staff member
You want to change disk, but when you remove the disk you want to change, Windows does not boot.

For example, although my windows software was installed on drive C, the EFI partition was installed on the SSD in drive E.

When I removed the SSD, Windows did not start.

Open the admin script and enter the following command.
You can then change the disk by turning off the computer.

bcdboot C:\Windows /s C:
