Hi! When I try to start any virtual machine (I have Manjaro and Zorin) the guru meditation screen pops up. I've tried to reset my bios settings to default (when it was working) and it still gives me this not so reassuring window.

The little guru meditated on a Triple Fault soon as it touched the OS CD:

A Triple Fault is Virutalbox's throwing up of the hands because something really unusual is wrong.

This time what that thing is isn't readily visible.

You have free use of VT-x, so no Hyper-V interference, which is good:

00:00:02.833621 HM: HMR3Init: VT-x w/ nested paging and unrestricted guest execution hw support

You're using 3D acceleration in the guest, which wouldn't be usable while booting from the CD-ROM. Try turning 3D off until after the guest OS is installed.

Though the following is probably not the cause of the trouble, slide your guest processors back to 2 until you get the guest installed. Modern OS's like 2 processors; more can slow down the guest until you pack on 3rd-party parallel-processing software that can use the extra cores.
