Need Help: Failed to Boot0001 and Boot0002 error

I'm having trouble running my Ubuntu desktop on my VirtualBox machine. I'm on MacOS (M4). I just followed the steps of downloading VirtualBox as well as Ubuntu set it up in VirtualBox, but after trying to run the machine i get , "BdsDxe: failed to load Boot0001 "UEFI VBOX CD_ROM" and "BdsDxe: failed to load Boot0002 "UEFI VBOX HARDDISK".

Any Help would be great.
