I've tried quite a few things to solve the problem, such as remove virtualbox, reinstall, remove again, build from sources, install countless dependencies that might be useful, check linux headers, verify SHA1 checksums of the images, change virtual RAM and disk size, change disk type from dynamically allocated to fixed and I'm still stuck. I just get a black screen with an underscore. The screen shows : Loading /live/vmlinuz.okĪnd then nothing. I get a warning (telling me that the window is optimized for 32 bits colors whereas the virtual screen is set to 24 bits) which I ignore and the main menu of the live CD appears telling me to choose an option. In storage -> IDE drive I choose a live-CD image of Kali (AMD64 or I386 i've tried both).

In system I remove floppy disk from boot order, and tick IO-APIC.Then I make a few adjustments in the configuration menu : I build a 'classical' virtual machine for Kali: I'm trying to boot/install Kali Linux in Virtualbox under Elementary OS (based on Ubuntu 12) as host on a 64 bits computer.
