I discovered that I can export from the old VirtualBox to OVF format just by manually changing the name of the file it will create from .OVA to .OVF. And the new VirtualBox on the Latitude will import it, except that at the end the import fails:
VirtualBox Error Failed to import appliance ... Windows 10.ovf Detail Result code NS_ERROR_INVAL ID_ARG (0x80070057) I tried it both ways - exporting as OVA and exporting as OVF, and the new VirtualBox will try to import either one, but at the end always gives the above error message. I also tried copying the Windows 10.vdi file to ~/VirtualBox/VDI on the new computer (where I had to create the folder first), but the new VirtualBox does not see the machine. I also tried putting it in ~/VirtualBox VMs, which is the default folder that the installer created on the new computer, but it still is not visible. At the end I decided to just reinstall Windows 10 in VirtualBox on the new computer from the .ISO that I still have. It took a couple of hours of swearing, but I finally got it installed, except when I launch it I get a screen with a lot of little squares instead of a Windows 10 screen. In VirtualBox the icon for Windows 10 appears and the Settings to the right also appear, and appear correct, but I can't figure out how to fix the video problem.

The format is not selectable, but (see above) the file that it will create appears in a box below and you can just edit the name to .ova or .ovf. >I do not bother - just: > rsync -a "VirtualBox VMs" .../home/$USER/ > rsync -a .config/VirtualBox .../home/$USER/.config/ > >Then start your new virtualbox and you should see everything as it used >to be. I don't understand the rsync commands above. The .vdi files are on one computer and they need to be copied to a new computer, and the computers are not directly connected. It is faster and easier just to copy files from the old computer to a USB drive and plug the drive into the new computer. And I already did that on the new computer, both to ~/.VirtualBox/VDI (which I had to create) and to ~/VirtualBox VMs (created by the installer of 6.1.26). Tomorrow I'm going to scour the VitualBox forums hoping to find step by step 'for dummies' instructions for how to install Windows 10 from an ISO. I should add that this is not a crucial matter. My old computer has Windows 2000, Windows XP and Windows 10, and none of them have been run for at least a couple of years; Windows 2000 for at least five years. If I had any brains I'd just forget about it. I should add that the old computer has Xubuntu 20.04.2 with VirtualBox 6.1.16 and the new computer has Xubuntu 21.10 with VirtualBox 6.1.26.
