Help: How to create Windows VM in Parallel Desktop 11 using existing Boot Camp partition?

Hi guys,
Need some help here.
I'm using Parallel Desktop 11 version 11.2.3 (32663). My iMac 5K 2017 is running macOS High Sierra.
I already have a Windows Boot Camp partition. I would like to create a VM in Parallel Desktop using the existing Boot Camp partition.
When I try to create a new VM, I don't see the option for "Use Windows from Boot Camp".
I have tried the methods mentioned in this article: http://kb.parallels.com/en/112941, but to no avail.
Would really appreciate your help. Thank you.

 

okay I think I know the answer to this already. Parallel Desktop 11 is not compatible to High Sierra.
This sucks.
