Hi ,
In my laptop I normally download the virtual box OVA and it works with 2020.4 ( I am using Virtual Box 6.1.18 in a Win10 HP ZBook)

If I dowload the 2021.1 OVA or update the 2020.4 OVA or install with the 2021.1 ISO the boot process remains always hanged in the same way:after around ten seconds the boot messages halted without any specific error.
Do you have any suggestion about how to solve this issue?
