Windows 10: Can't shrink volume more than 2GB

Good day, I am an MCSE in windows 10The UI won't allow me to shrink more than 2GB off a 200GB free drive, any ideas? All optimization has been done, hibernation disabled etc no luck. Any insight would be great I'd like to duel boot Best,Dylan

Shrinking a volume

Hi tfd3

Close Disk Management

Click your Start Button, then just type cmd

From the resulting list, right click Command Prompt and choose 'Run as Administrator'

Paste this command and hit Enter:

diskpart

Paste this command and hit Enter:

list volume

(note down the number of the Volume you intend to shrink)

Paste this command and hit Enter (replace x with correct volume number)

select volume x

extend filesystem

When that completes, close Command Prompt and try shrinking that partition again in Disk Management

 

Shrinking a volume

Hi, Dave. I followed your instructions. All seemed to go well, but Disk Management still reports "The parameter is incorrect" when I try to shrink the volume.

Shrinking a volume

Thanks, Stefano. At your suggestion I did a Defragmentation on the drive I want to shrink. That took almost a day on a 1 TB drive. The drive is now 0% fragmented. But still I'm getting "wrong perameter" when I try to shrink the volume. Here's a screenshot
of the dialog window for shrinking the drive:

The amount of space I last put in to shrink was 50012. Any idea why that didn't work?
