'Choose existing disk' and select the vdi disk image.Įither make the bootable disk the 'IDE Primary Master', or immediately after booting press F12 and select the boot disk. In the storage settings, select the IDE controller, and 'add hard disk' using the buttons at the bottom of the screen. Usually, Virtual Box creates an alias from /usr/bin/VBoxManage to /Applications/VirtualBox.app/Contents/MacOS/VBoxManage.) (VBoxManage is a tool installed by VirtualBox. VDI is the native Virtual Box disk format. In order to tell Virtual Box that the file is a hard disk, you must first convert the IMG file to a VDI file. This is unlike ISO distributions, which do contain a partition table (even though their content is also not compressed). The IMG files distributed by FreeBSD contain a raw UFS file system raw meaning without overhead (metadata), compression or partition schema. While it should not matter (you have a file which contains a bootable system), in practise I only got it to work using a bootable hard disk. So you either have to tell Virtual Box it is a floppy, regular hard disk, or CD. It is not possible to tell Virtual Box you want to boot from a USB disk.
