There is no bootable ISO image or CD/DVD disc inserted into the virtual optical drive of the VM. If you have another disc that is the same, or you are able to record another copy of the disc – try these options. Try to clean the disc surface carefully, polishing the scratches with special sprays. This situation is made worse if the scratches are located near the center of the optical disc where the table of contents is recorded as well as the lead-in area that includes information about disc tracks and sectors of the CD/DVD disc. Scratches and dirt on optical CD/DVD discs can make the disc data unreadable. VirtualBox allows VMs to use a physical CD/DVD drive of the host machine that can be connected to a VM in settings. Unfortunately, in most cases, it is impossible to repair a corrupted ISO file stored on a damaged HDD. For example, how to manually create a bootable macOS installation ISO image is explained in the blog post about installing macOS on VMware ESXi. Download another ISO installation image, clone a physical DVD disk to the ISO image, or create a new ISO bootable image manually. If some fragments of the ISO disk image are located on bad (damaged) blocks of the HDD (hard disk drive), the ISO file can become unreadable, and a VM will not be bootable from this ISO file. Sometimes a VM cannot boot from an ISO image when the hard disk on which the ISO image is stored gets damaged. The disk on which an ISO file is stored is damaged Verify the checksum of your file after downloading the ISO image by comparing it with the reference checksum on the source site. Sometimes the wrong disc may have been inserted by mistake. Check the media you have inserted into the optical drive attached to the VM. Burn another bootable CD/DVD disc or create a bootable ISO disk image correctly and try to boot again. The same situation may happen when an ISO image is created incorrectly without creating a disk boot area. If a physical CD/DVD disc was burned as a data disc without using the bootable disc option, you won’t be able to boot your machine by using this disc. If you want to boot from a CD/DVD disc or an ISO image but find that the disc has been created incorrectly, you may get the No bootable medium found in VirtualBox error.
