#VIRTUALBOX BOOT FROM USB ISO IMAGE MAC#

If I try to boot from this newly created image, Virtual Box gives an error 'FATAL: No bootable medium found! System halted.'. Unfortunately, this does not seem to create a partition. For IMG there seems less conventions, but you may want to try -format RdWr to convert to a NDIF read/write image). Use -format UDZO for zlib compressed DMG files. (Similarly, use hdiutil with -format UDRW to convert from IMG or ISO to DMG (actually: UDIF read/write image) which can be used with dd. To convert the raw disk image to ISO, run:

In order to tell Virtual Box that the file is a CD, you must first convert the IMG file to a ISO file. It seems that the IMG files distributed by FreeBSD are not suitable (perhaps Virtual Box expects an image with a partition table? I tried converting with hdiutils convert but to no avail.) In that case, choose one of the other methods (hard disk booting or CD booting). If you get an error 'Could not get the storage format of the medium '' (VERR_NOT_SUPPORTED)', Virtual Box can't read the IMG file. Would you ike to choose a virtual floppy to put in the drive or to leave it empty for now?' Select 'Choose disk' and select the appropriate IMG file. You will be asked: 'You are about to add a new floppy drive to controller Floppy Controller. Now use the disk icon to add a new floppy. You first need to 'Add Floppy Controller' with on of the small buttons at the bottom of the screen. In the storage settings, there is by default only a IDE controller. Otherwise, Virtual Box will try to boot from the (still empty) default disk, and you get the error 'FATAL: No bootable medium found! System halted.' '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.
