Hello, I have virtual box 6.0.4 r128413 (Qt5.6.2)
I would like to install debian as guest.
So I do: machine-> new -> debian32 bit-> 1024 mb ram -> vdi disk
then I go to settings and I notice that there are not valid settings, virtualbox is telling me to disable in system -> acceleration the hardware virtualization.
then I chose an iso for the ide controller: debian-9.8.0.i386-netinst.iso
I click ok and then start.
there is the virtualbox logo, then there is the debian cli asking me what I want to do.
I choose Install.
and then nothing happens.
All I get is a black screen.
I attach the virtual machine logs.
can someone explain what is happening?

You'll find life much easier if you enable VT-x in the VM settings. Probably you can't do that right away because something on your host is preventing you from using it. For that you should read a related FAQ: I have a 64bit host, but can't install 64bit guests.

Also, I'm pretty sure that IOAPIC needs to be enabled for a Debian guest.

Moving this topic to Windows hosts since it is not a generic "Using VirtualBox" question or solution.

You need to enable virtualisation (VT-x) in the motherboard / PC / laptop BIOS. Your Intel i5-4570 CPU supports it. See your PC's manufacturer help on how to do this. Also, make sure that nothing else has an exclusive hold on the VT-x. Fixing this should also give you the ability to install 64bit guest operating systems.

Next, I would go into the guest settings and change the vGPU from VMSVGA to VBoxVGA. The former is a new addition in VirtualBox 6.0.x and has a few issues at the present time. While you are there, increase the video RAM to 128MB from its current setting of 16MB.

thank you very much!
enabling (VT-x) worked like a charm
