Paralells Reports Missing Operating System with Windows 10 bootcamp Partition I've installed Windows 10 Release Candidate on a brand new SSD drive. My Windows Bootcamp partition boots and runs correctly, but tends to crash ocassionaly. I believe this is due to bootcamp drivers that haven't been updated for Windows 10.

I've heard reports that running this setup through Parallels should resolve these crashes. When I open Paralells, however, I don't see the (typical and easy) bootcamp option:


(Notice that there is no bootcamp option)

After some searching, I've found this answer that links to an article about setting up the VM manually. I've followed the steps, but get the following error on booting:

Trying to boot from SATA drive 1...
Missing Operating system




I've even tried choosing a few different locations (SATA 0:2 - SATA 0:3)
but am still getting the same error. 

I've also followed this Paralells support article, although I only did the first part where you run DISM /Online /Cleanup-Image /RestoreHealth, but am still having the same issue.



What is the issue here? 

So my setup is: 


OS X Yosemite 10.10.4


Paralells Desktop 10 10.2.2 (29105) Trial
Actually, after my comment above I played around a bit and got to the same screen as the original post.

However: you should choose edit partitions. Chances are there will be 2 partitions of which the second was not selected (which was my actual windows drive).

Selecting the second partition instead of the first actually resolved it for me.
