After a while of working properly, Win7 (32 bit) displays a black screen after booting. Booting in safe mode without issues. Earlier version of this same installation is still working properly. Chipset settings , or 3D/2D acceleration settings do not change anything.
Is there anything that could be done to make it work again? thanks.

Re: Windows 7 black screen
This seems to be an issue with your guest, not your host. Moving from "OSX Hosts" to "Windows Guests".
We need to see a complete VBox.log, from a complete VM run:
We need to see a complete VBox.log, from a complete VM run:
- Start the VM from cold-boot (not from a paused or saved state) / Observe error / Shutdown the VM (force close it if you have to).
- With the VM completely shut down (not paused or saved), right-click on the VM in the VirtualBox Manager and select "Show Log".
- Save only the first "VBox.log", ZIP it and attach it to your response. See the "Upload attachment" tab below the reply form.

Re: Windows 7 black screen
You have assigned all your CPUs to the VM. The host is going to run low on resources, since VirtualBox cares about physical processors (cores), not logical ones (threads). Your i7-4870HQ has 4 cores.00:00:01.382472 NumCPUs <integer> = 0x0000000000000004 (4) 00:00:01.547582 CPUM: Physical host cores: 4
Other than that, I can't find anything out of the ordinary in your log. The only thing I could suggest at this point is to boot into safe mode, and re-install the Guest Additions (GAs). When asked if you want to install the basic Direct3D, select "No". That will install the WDDM drivers instead of the XPDM ones.
Finally, what is "/Volumes/e_ssd/VirtualBox VMs/Win7_e Clone_1/Win7_e Clone_1.vdi"? An external drive?

Re: Windows 7 black screen
Thanks, but didn't work. CPU is now 2 cores, and reinstalled the Guest Additions but still black screen.
Yes, e_ssd is an external SSD drive. But I had this same issue before, while disk was still on the main drive. Before I was returning to the snapshot that worked, which I accidentally lost while cloned the machine to external drive.
Not a big deal though, more curious about what could be causing this, than in trouble.
