Create virtual disk from bootable usb

 Open disk maangement using run--> diskmgmt.msc and note the disk number of usb pendrive.

Say disk 1.

Run below command using virtualbox command line.

VBoxManage internalcommands createrawvmdk -filename C:\usb.vmdk -rawdisk \\.\PhysicalDrive#

Replace # with disk id for example PhysicalDrive1 for disk1.

Now, usb.vmdk contains a reference to the usb flash drive.

It need to connected still.

Reference: 1 2

If you want a complete copy of the disk then use the clone command and it will generate a new disk with all data but without link to the usb.

VBoxManage clonehd <old> <new> --format VDI
