I have VirtualBox Portable installed from I moved it on a USB drive and added a virtual Ubuntu.

It works fine on the computer I created it, but moving the usb drive to a different the Ubuntu does not start any more.

I already changed location descriptions in <machine>.vbox and the VirtualBox.xml. When pressing Shift while starting the GRUB loader comes up, so I tried the recovery mode. Same here – startup freezes and nothing happens. Any hints for me?
