It's a cliche thing to say but one typo and there's a very real possibility you'll nuke your system. The following instructions assume you've moved it to /media/dave/disk.img ( dave is an external USB disk)īefore you do any serious writing, make sure you have backups. If you're planning to write it to the disk that it's currently sitting on, you'll want to stick it on a separate internal disk, or, worst-comes-to-worst an external disk. Move /media/wherever-the-image-is/disk.img somewhere that you're not about to write to. VBoxManage clonehd your-virtualbox-disk.vdi disk.img -format RAW Qemu-img convert your-vmware-disk.vmdk -O raw disk.img Load a terminal and fire in: cd /media/wherever-the-image-is/ You can do this from your current system without having to boot to a LiveCD. You can but I personally feel it's more convenient to write it to an intermediary, standard image first. Preliminary step: Convert the disk to something usefulīoth VMWare and VirtualBox (amongst others) use disk formats that don't lend themselves well to being written directly to disk. It's not even that hard, it just takes some time, a Ubuntu LiveCD, sticky-back-plastic, and an external USB disk (if you don't have more than one internal disks).
