I'm using Virtual Box 5.2.22 r126460 on macOS Mojave 10.14.2.
When I launch Debian 9.6.0 amd64 I got a black screen with a cursor blinking.
I can't figure out how to fix it.
I have no 2D or 3D acceleration enabled.

Re: Black screen with blinking cursor
Do you really need 22769 MB of RAM for your guest? Isn't 4 or 6 or 8 GB enough? Not a show-stopper, but you're going to be stressing your host unnecessarily...00:00:03.640639 Host RAM: 32768MB (32.0GB) total, 25377MB (24.7GB) available 00:00:03.756171 RamSize <integer> = 0x000000058f100000 (23 875 026 944, 22 769 MB, 22.2 GB)
On the other hand, you completely neglected your poor VRAM. Take that all the way to the max 128 MB, you can afford it...00:00:03.756465 VRamSize <integer> = 0x0000000001000000 (16 777 216, 16 MB)
For future reference, you should completely shut down the VM before grabbing the VBox.log. Then ZIP it before attaching it to your response. It helps save a (virtual) tree or two...

Re: Black screen with blinking cursor
Setting memory to arround 8GB and VRAM to 128MB doesn't fix the issue.

Re: Black screen with blinking cursor
I did a fresh installation and it works now.
My mistake was arround grub installation that I did manually instead of the automatic one that was not proposed by default.

Re: Black screen with blinking cursor
So you selected in a sense the wrong place to boot from?
