I can't open windows 10 using parallels in my MAC. There is a permanent black screen
I have the same problem. Have tried everything including uninstalling. Still won't work. I need this computer to work ASAP!
Guys, please try Actions-> Reset
or check this KB article for the resolution steps
I have the same issue, but the KB article is no help because the first step in the article is to click on the start menu. How can I click on the start menu if the Windows 10 screen is black?
Hi, which version of Parallels Desktop are you using? And when does the issue appear? Maybe after Windows or Parallels Desktop update?
Previously Parallels worked fine. Then, it says my mac out of space. So i have move the virtual machine to hard drive. however, when i double click to launch Windows 10, it only shows screen with temporary window and buffer logo and stopped at blank/ black screen. I have tried Action> Reset, did not work. I have quit and restart Mac, I have restart the window 3 times, also did not work. Please HELP.
@hamidi, did you receive the "out of space" warning after starting your VM?
I need help too. Black screen, nothing fixes it.
I have an interesting variation of black screen - see attached.
I've tried all the steps from stop/reset/start to booting in safe mode. Still only get black screen.
MacOS Mojave/Parallels 13
When does it appear? After any updates?
Could you please test the same behavior with Parallels Desktop 15 during the free trial period?
Updated to Parallels 15 - now just pure black screen (see attached)
Could you collect the tech.report right after the issue reproduced and post the report's ID here.

I have been experiencing this post-login black screen for a number of days as well. I am running Parallels 15, and this appears to have begun after my W10 VM took the "major feature update" to Windows 10 Version 1803.
The initial update from 1709 to 1803 still seems to allow the VM to work properly, but one of the many post-1803 bugfix updates that get installed immediately after the big feature update seems to be causing this. I'm now using the Windows diagnostic tools wushowhide.diagcab and wu10.diagcab to attempt to suppress specific individual updates, so that I can see which update is responsible.
Luckily, I have a 4-TB scratch disk available, so I can shut down and archive the VM prior to each individual update- this prevents having to go all the way back to 1709 and endure the multi-reboot Windows 1803 update process for each test. If and when I can conclusively identify the culprit, I'll post that info here.
I note that it is possible to send ctl-alt-delete, start the task manager, and manually launch the control panel and Explorer, even despite the black screen. However, when Explorer starts, I get only a single window floating on black. It has not yet been possible to get the actual desktop environment/start menu/etc, only individual items. That may be the key to debugging this.
One final note: I have also revirtualized the source PC *after* all the 1803 updates were done on it (which involves a clean installation of Parallels Tools after virtualization), and it works just fine. Thus, my current conjecture is that this is the result of a specific update killing Parallels Tools. I haven't had any success reinstalling Parallels Tools from the task manager after it happens: it seems that a running desktop environment is required to do so.
My bet is that it is some obscure video driver conflict resident in one of the early 1803 bug patches, that is then silently corrected by the *next* 1803 bug patch...
