VirtualBox comes with a tool to convert an img to it's vdi format:
Quote: vboxmanage convertdd my.img my.vdi |

I just realised I forgot to ask what type of image it is. VirtualBox will run a floppy disk image as it is, only a hard disk image needs to be converted.
If that's what you have done, you might have to remove the image from the list (possibly rename it) and add it again. [vdi's have a unique ID that gets checked] |

Code: Could not get the storage format of the medium 'path/myos.img' (VERR_NOT_SUPPORTED) |

... 'path/myos.img'...
Are you sure you used the vdi that was generated? |

In my ubuntu linux in Vbox, you first make a hdd image, just the default than click on floppy, click mount, then you highlight image file, find the img image and click OK.
Then when you click start (if the floppy img was bootable) it should work. |
