Thanks for taking some of your precious time checking my case.
I have configured a windows 7 on my VBOX (installed in Ubuntu 20.04) and the message popup when I launch it.

VirtualBox - Guru Meditation

A critical error has occurred while running the virtual machine and machine
execution has been stopped.

Please upgrade VirtualBox to the current release (6.1.32).

You should also give Win7 2 CPU cores. I would also double the RAM allocation (to 8192GB) since you can easily afford it.

Hi mpack,

Thanks for the help.
After upgrading from 6.1.22 to 6.1.32, the error didn't pop up.
