Do not mount the place where you want to write to. Mount your the place where your qcow2 image is being stored (eg the external USB disk as /media/dave). This assumes you're going to overwrite a whole disk.īoot into an Ubuntu Live CD and click Try Ubuntu. Write the image to a disk of its very own
CloneZilla can help you take whole disk backups if you have somewhere for that data to be stored. 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. Qemu-img convert test.qcow2 -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.
Preliminary step: Convert the disk to something useful
It's not even that hard, it just takes some time, a Ubuntu LiveCD, and an external USB disk (if you don't have more than one internal disks).
