Something nice and slightly risky today: a tutorial explaining how to attach raw devices like bootable external USB drives as storage medium to VirtualBox, including word of caution, how to correctly identify physical hardware, how to create, map, and add raw device files to virtual machines, how to resolve errors around permissions and groups, testing with Rufus-created bootable media, some other tips and tricks, and more. Have fun. https://www.dedoimedo.com/computers/virtualbox-raw-disk.html Cheers, Mrk
I've been doing this using "vboxmanage internalcommands createrawvmdk" so long I did not knew you could do it with "vboxmanage createmedium". I like this method better, since it is documented.
