How do I covert my 2 backup mage1.img and image0.img fils into 1 .iso file to reinstall

  • 772

I have backed up Linux however my VM backup results in 2 image files. image1.img and image0.img. I am stumped and would Like to have some suggestions on how I can use the image files to recreate a new bootable Ubuntu server install .iso. I basically want to clone my entire ubuntu server configuration that I have established.

  1. To combine 2 or more files it is easy to use cat as this:

    cat image1.img image2.img > result.img

    But to make a bootable .iso image tasks is more complicated, xorriso is a nice tool, please refer to https://willhaley.com/blog/custom-debian-live-environment/ xorriso part.

    In addition if you made .img file using dd you can restore back your OS using a live image running a command like this:

    dd if=/path/to/image1.img of=/dev/sdxx bs=64M
