Parallels 10 Black Screen with Windows 7

Hello,

I have been using Parallels 10 with Yosemite mostly problem free since the OS and Parallels have been upgraded... until this morning. There was a Windows 7 update this morning that rendered Parallels COMPLETELY unusable. I get nothing but a black screen now and when I go into Coherence, nothing shows up.

This is a problem I've had before, only I can typically just reinstall Parallel tools and it resolves the problem. This time it's different and it's not just affecting the Coherence mode, but the whole VM. I cannot access Windows AT ALL, meaning I cannot rollback the update, or uninstall Parallel Tools.

Here's a few things I've attempted: I've restarted the VM, shut down it down, reset the VM, rebooted my Mac, upgraded to Yosemite 10.10.3 as well as attempted to reinstall Parallel Tools. Nothing has helped and the VM is not working at all!

Does anyone have any suggestions? I've contacted support (Support Code: 42596-50433), but am concerned that they will not be prompt in getting back to me based on others comments. At this point Parallels is USELESS and it is setting me WAY behind with my work...

Aside from uninstalling Parallels and attempting a full reinstall, does anyone have any suggestions?

Thank you
Nick

Hi Ram,

Thank you for providing me with that suggestion. I have attempted the suggested steps, however this did NOT resolve my issue. In attempting to boot windows in "safe mode", it unsuccessfully boots windows. It goes through a series of command prompts, then just goes to a "Black Screen" again. At this point Parallels is completely NOT working and I am unable to access ANY files in Windows, nor can I access any information in Windows. This is absolutely detrimental to my small business!

To answer your questions
1. I have filed a support ticket as I indicated in my original post. The Support Code is: 42596-50433. I have NOT received any response or support yet.
2. The Parallels Desktop build installed on my machine is: Version 10.2.0 (28956)

The Parallels Desktop build is running on an iMac with OS X Yosemite 10.10.3, and the VM is running Windows 7 Ultimate.

Your prompt attention is appreciated to help me resolve this.
Thank you,
Nick Forte
