virtualbox.org

Hello,
I try to install Ubuntu 20.04 LTS on my Windows 10 pro laptop.
However, the VM is stuck on a blinking cursor if I don't interact vith the VM, or if I try to install or to use the Live Machine.
I installed Slax, and it work well.
Can somebody help me ?
Thanks,

EDIT: I added the log.

You allocated more RAM than you have available. Frankly, your host has barely enough RAM for one modern OS, never mind two.

Plus, you have Hyper-v enabled.
