Problem Installing Leap 16 on VirtualBox is truly frustrating.
Choosing the default options for the disk and partitions—the system simply does not boot. I have tested this on several computers and the result is always the same: No operating system.
“What was happening was that after the installation, when I selected the option ‘boot from hard drive’, the system would not start and displayed the error: ‘The virtual machine failed to boot’, together with a mount option.
I removed the floppy and DVD boot options in VirtualBox, and that solved the issue.”
