[Solved] Can't install virtual machines in VM VirtualBox

Everytime that I try to install Fedora (33 and 32) it asks me for the .ISO file, starts and asks me to "check the file and install" or "install". Both options start with a black screen and do nothin more, even after an hour.
I have this problem with Fedora, but also with Windows 10 and Windows server 2019.

I give the virtual box enough space (12GB for fedora and 30GB for windows/windows server), 4GB of RAM, 4 cores, 3D acceleration, 128MB of video memory and it is connected to the internet via NAT, Host-only and bridged network. Can't seem to find the reason why it doesn't work...
Don't think it is the specs of my computer either: 16GB RAM, intel i7-3770K @ 3.50GHz, Windows Education running 64-bit, Hyper-V is also turned on...

Hyper-V is enabled and needs to be disabled. See HMR3Init: Attempting fall back to NEM (Hyper-V is active).
