Can't Upgrade to Windows 10

I have a Mac computer which is currently running on OS X Yosemite version 10.10.5
I am running Parallels 10 version 10.3.0 (29227).
I can't seem to upgrade to Windows 10 because I get this error message: Parallesls Display Adapter (WDDM)
The display manufacturer hasn't made your display compatible with Windows 10.
I am currently running Windows 7.1 in the background.

I would like to know that if I upgrade to El Captain and buy Parallels 11 will I then be able to upgrade to Windows 10?
