Can the hard disk size be increased?

[ChrisR4]

I'm trying to upgrade from Windows 8.1 to Windows 10 on my Parallels 11 VM. The hard drive is currently at 64GB. Is there anyway that I can increase the hard drive space using Parallels so that I can install Windows 10? I need about 9GB according to the Windows 10 Setup.

Hi ChrisR4, We suggest you to follow the steps in this article to increase the Hard Disk space for your Windows Virtual Machine. Additionally, refer to this KB to upgrade your Windows Virtual Machine.

That worked successfully! Thanks! Now, when I try to upgrade to Windows 10, it tells me Parallels Display Adapter (WDDM). The display manufacturer hasn't made your display compatible with Windows 10. Check with the manufacturer for support. Is this really a problem, or can I ignore it? I realize that when you upgrade to a newer version of Windows, some device drivers aren't updated yet, but I wanted to make sure this wouldn't be a problem.
