You will obviously have to be mindful of disk space for where you move it around to. Now you have a however large whatever.iso. Having your ext4 partition mounted as /whatever mkisofs -o /somehwere_else/whatever.iso /whatever
Image backup are (almost always) the worst way to backup a filesystem. It's more useful, can be extracted easily to anywhere you want, and doesn't waste space or time copying empty or unused sectors. with tar or rsync or even cp -a) rather than an image backup. Personally, I would recommend a file copy (e.g. Or even dual-boot between Debian 9 and Debian 10. Then you can just mount the old drive somewhere on the new system.

BTW, if you took an image of the entire disk rather than just a partition, you could run your old system as a VM in your new system.Īnother alternative is just to install a second disk and install the Debian 10 on that. To mount it: qemu-nbd -connect=/dev/nbd0 /path/to/backup.qcow2īoth qemu-img and qemu-nbd are in the qemu-utils package. Or, as mentioned by user1133275 in a comment, you could use process substitution: ddrescue /dev/sdXn >(ssh 'cat > backup.img')įinally, if you want a compressed, mountable filesystem you could use qemu-img: qemu-img convert -c -O qcow2 /dev/sdXn backup.qcow2 with scp) afterwards, or write it to an NFS mount. If the partition has read-errors, you might want to use ddrescue instead of cat: ddrescue /dev/sdXn /dev/sdYiĭdrescue won't write to stdout (or read from stdin, either), so if you want that backup.img on another machine, you'll have to copy it (e.g. Or if you want a progress bar while it's copying and/or control over how much buffering is used during the copy, you could use pv: pv /dev/sdXn > backup.img You could use dd instead of cat, but there's no good reason to do so: dd if=/dev/sdXn of=backup.img Or to a file or partition on another machine: cat /dev/sdXn | ssh 'cat > backup.img' Click next to install the driver.As root, just cat the partition to another partition: cat /dev/sdXn > /dev/sdYi

You’ll notice that Windows doesn’t have Internet access at first. Save the settings, and select Reset in the main BIOS menu to test out your new resolution. This may change in the future, but we have to use ramfb for now. It’s limited to a relatively small resolution, due to standard VGA for ARM64 not being supported, and having to use ramfb instead. Then, set your display resolution up to 1440x900 in Device Manager > OVMF Platform Configuration (or any other resolution you want to use).

If something goes wrong and you need to revert to a snapshot, just do Remember to take another differently-named snapshot after installation is complete (I like to name mine clean_install).
Qemu-img snapshot disk.qcow2 -c brand_new That way, we won’t have to redownload the VHDX file. We are going to take a snapshot of our QCOW2 file, just in case anything goes wrong during installation. Once it’s done, delete the original VHDX file, as we no longer need it. Now you just wait this might take a while. Remember to change Windows.vhdx to the path to your own vhdx file. Qemu-img convert -O qcow2 Windows.vhdx disk.qcow2 We want to convert it to a QCOW2 file, so we can take snapshots of it and compress it. Now that you’ve built QEMU, the Windows VHDX is probably done downloading.
