I have so uploaded a new iso and then attach the iso to a new vm. But when I try to boot the vm I obtain this error: booting from dvd/cd... boot failed: could not read from cdrom (code 0005) no bootable device Forum Solution: Find the location of the ISO image in the storage domain (search for the UUID in the file system) and re-copy the ISO over the top of the file. Just be 100% sure it's the ISO and not a VM disk (reference modification time, size etc). Once you replace the "uploaded" file with the ISO directly, everything works as expected. Kindly share detail steps on how to upload ISO image directly to Storage domain with UUID
