When changing the drive letter in Disk Manager you may receive an error that says, “The parameter is incorrect”.
This can happen is the pagefile is on that drive. Move the pagefile to a different drive, reboot, then try again.
My D drive was getting a little full so I got a bigger drive to switch it out. Before switching it out I opened up Disk Management & this is what I saw.
Not only is the D drive marked as System & Active but it is also Disk 0.
After doing the steps below, Windows booted up just fine with the new D drive.
- Right click C & select Mark partition as active.
- Open an elevated command prompt & type bcdboot c:\windows /s c:
- Plug C drive into SATA0.
- Plug the new D drive into SATA1.
- Power on the PC & go into the bios.
- Verify the boot order of the hard drives.
Now looking at Disk Management everything looks much better. Disk 0 is the C drive & Disk 1 is the new D drive. The C drive is System & Active.
