VirtualBox - How easy is it to export Ubuntu VDI to raw partitions

Question

I would like to ask how easy is it to export an Ubuntu VDI in VirtualBox to raw partitions and make them boot natively with the boot menu?

Answer 1

Pretty straight forward. Boot the virtual using clonezilla and copy the VDI data to a file. Then from outside the virtual use clonezilla to write it to a physical disk.
