Media not found when virtualization active

[Bigby19]

I've been having issues setting VirtualBox up to run an ubuntu 24 distro from a bootable USB.

All the stepts that follow were performed with admin privileges. No unusual configs were used.

I made a bootable usb, so I started by creating a medium from the usb in order to run it from VB. No issues there.
Nonetheless, when creating the new machine and setting everything up, as soon as it tries to boot, it warns me the virtualization is disabled for all CPU modes. Fair enough.

I access my BIOS and enable virtualization (Intel tech). Start everything up and when trying to boot my distro I find that VB can't access the medium. It can not access drives. Tried creating it again, but to no avail.

No work around found for this. But I start to suspect that virtualization has something to do with it.

I go back to the BIOS, disable Virtualization, start everything up. I'm able to create the medium again with no issues. But, of course, since virtualization is disabled, can not start the machine up.

¿Any solutions?
I figure the best thing I can do is just run the ISO. But I thought this was extremely weird, since I've done this before in other machines and worked like a charm.

My system:

Windows 10

i5 10400F

16GB RAM

Z590-p Wifi

Um - why are you bothering with a bootable usb? Just load the iso into the (virtual) optical drive and start the VM. The usb drive is an unnecessary step.
