I am currently trying to install GhostBSD 4.0 B3 under Virtual Box on a Windows7 64bit.
BSD 64Bit VM
I am able to boot off the ISO just fine and get to the Desktop. I run the Installer and fill out my Country, Use the Enire HD with BSD Boot Loader, my User info, etc. When I “Forward” I just go back to the Desktop and the installation doesn't happen.
I have also had this issue under VMWare 3 and 5 on a Mac and VMWare 9 on Windows. No matter what Virtual Machine software I use I get the same results.
