VirtualBox no bootable medium found

What causes the VirtualBox no bootable medium found an error? According to the investigation, there are several common reasons that can lead to the VirtualBox fatal no bootable medium found error:

  • The bootable ISO disk image is not bootable or has been created improperly. If the physical CD/DVD disc was burned as a data disc instead of a bootable disc, you will get the fatal no bootable medium found error when booting your VM by using the disc.
  • The ISO image you have created is stored on a faulty disk. In some cases, you cannot boot the VM from an ISO image if it is stored a damaged hard disk drive. Since some fragments of the ISO image are coincidently located on bad blocks of the hard disk, the ISO image will be unreadable.
  • The virtual optical drive is empty. If you insert the bootable disc into the virtual optical drive of VM incorrectly, the VirtualBox fatal no bootable medium found error can occur.
  • The boot order in the VM settings is incorrect. If you haven’t selected the virtual hard disk as a boot device in the boot order list or the disk boot image contains lower boot priority, you can get the no bootable medium found VirtualBox fatal error.
  • The virtual optical disc drive is missing. When the virtual CD/DVD drive is missing from VM configuration, you may get the no bootable medium found system halted error.
  • The disk controller is configured on SATA. In many cases, SATA can only work properly when it has been used as the first controller. Otherwise, you need to burn the ISO image on an IDE controller to avoid the VirtualBox error.

The possible causes of the no bootable medium found error has been analyzed. Now, let’s start exploring methods to fix this vexing error.
