I've seen this error for full-blown installs, but not for an install into VirtualBox, so observations about UEFI and the like don't apply (as far as I can see).
I'm trying to install Lubuntu into VirtualBox. All goes well until the actual package installation starts where, after a while, a message appears saying that grub-pc installation failed (no reason given). I can pick the other options presented (install to a different location, don't install a boot loader, ignore), but clicking on the continue button justs does nothing and I have to force the machine to close down.
There are other VMs installed: Windows XP, Windows 7, Ubuntu Mate, Manjaro. All of these are fine. In fact I did have Lubuntu 15.10 installed as well, but it somehow lost its connection to the internet after upgrading to 16.04. I couldn't solve that one either, so decided to reinstall. All the other VMs are fine.
At one point I was getting some errors about lack of disk space, but I think this is a red herring as it ocurred not on a full install but on an attempt to recover a failed install. And the VM reported a Virtual Hard Disk of 8Gb with only 3Gb used.
Any suggestions would be gratefully received.
Best regards
Peter

1The problem actually was, that the
/bootpartition wasn't created, even though it was shown in the UI. It's still possible to get everything running with the guided partitioning, but when you're asked toWrite the changes to the disk?, you need to go<Back>to see a detailed list of all partitions. When clicking<Next>, the installation will finally recognise and partition everything correctly and as expected.
