Every Linux VM boots to a black screen

Post by HenryM »

I have tried a few Linux distros, and every one boots to a black screen. This happens whether I boot from an ISO file, or create a new VM and use a virtual hard disk from OSBoxes, or if I use a prepackaged Kali machine from Offensive Security. How do I fix this? The only VM that has worked so far is FreeDOS. My computer is capable of virtualization, and it has sufficient CPU and memory.

Update:
I installed the expansion pack, expanded the VMs memory to 4 GB, and increased the processor to 4 cores. It still boots to as black screen. The hard disk comes preconfigured as actual size 10.04 GB and virtual size 80 GB.

Pick one VM, then provide a VM log file. Make sure the VM is fully shut down, then right click it in the manager UI. Select "Show Log" and save "VBox.log" (no other file) to a zip file. Attach the zip here.

You have Hyper-v enabled. Read HMR3Init: Attempting fall back to NEM (Hyper-V is active).

Topic moved to Windows Hosts since the guest is mostly irrelevant.

Is there any way to run both? I do not run them at the same time, but I have both installed.

I have heard that some people do that (*), but I've never tried it myself since I have no interest in Hyper-v or any related Windows feature.

(*) in fact the FAQ I referred you to has a discussion of this at the very end.

FWIW, I'm one of the people using the method described in the TenForums tutorial (which mpack is referring you to), and I can confirm that the method works as expected.
