VM VirtualBox is Oracle's virtual machine software. In the complete installation virtual machine, you can attach and use any USB form host computer. But when you want to boot the guest virtual machine from a bootable USB, the attachment isn't useful. Then you can try this tip:

• Plug your USB into the host computer and get the disk ID number in Disk management:

• Run Windows command prompt as administrator. Input following commands:

cd "C:\Program Files\Oracle\VirtualBox"
VBoxManage internalcommands createrawvmdk -filename "C:\usb.vmdk" -rawdisk \\.\PhysicalDriveTHE_DISK_ID_NUMBER_HERE

• Return VirtualBox, open virtual machine settings and choose to add file "C:\usb.vmdk" as a virtual hard disk

• Now, when you boot up virtual machine, you can choose to boot from USB disk (press F12 to choose boot devices).

Wish succeed!
