Black screen when starting windows after upgrade to 20.0

[Jean-LucN]

Hi,
I installed Parallels Desktop latest update this morning. I am now unable to launch my virtual machine (Windows 10). When I try to start the VM, there is first the normal display of the starting Windows screen, then the following message appears : "Vérification des disques après un arrêt incorrect. Veuillez patienter... Ne quittez pas l'application afin d'éviter toute perte de données" ( which translate like this : "checking of disks after an unexpected stop. Please wait... Don't quit to avoid any data loss".

After that, the message disappears and the system display the first screen again for a few seconds, then the display is completely black and nothing changes even when I wait several minutes.

I already tried everything I could find to fix the "back screen" error without any success. I could not launch Windows in Safe Mode because the system freeze very early and even resetting many times the virtual machine on a row doesn't trigger windows to start in Safe Mode.

I depend a lot on Parallels desktop for my work, thanks in advance to help me solve my problem ASAP.

Best Regards

Jean-Luc

Hi Jean-Luc,

That sounds incredibly frustrating, especially when you're relying on Parallels for work! The issue with the black screen after the disk check could be related to a corrupt virtual machine file or a problem during the update process. Since you can't access Safe Mode, I would recommend trying to boot from the Windows installation media within Parallels and running a repair. Another option could be restoring the VM from a previous backup if available.

If you haven't already, you might also want to try reaching out to Parallels support directly--they might be able to provide a more targeted fix.

Best of luck, I hope it gets resolved soon!
