Sometimes it takes a while for the .iso image to boot.
https://www.virtualbox.org/manual/UserManual.html
This is the users manual for virtual box.
You might check you virtual box settings before starting.

Hi,

I create VirtualMachine to use VirtualBox.
and jammy-desktop-amd64.iso use to boot.
then grub menu display console, and I select Ubuntu.
soon, displayed error

error: invalid magic number
error: you need to load kernel first
Press any key to contine...

soon, grub menu display again.

and I create another VirturalMachine to use VirtualBox at same PC.
and ubuntu-20.04.4-desktop-amd64.iso use to boot.
soon, ubuntu boot up.
I think jammy-desktop-amd64.iso have some problem.

Did you execute a checksum test on the iso file?

Have you tried a new download?

If the checksum does not match, then this is an indication that something went wrong with the download.
You have to do a new download and verify that the checksum is correct.

Can you help with this problem?
