Virtualbox also has a converter, if you start with the original hard drive (full drive, not the partition):
vboxmanage convertfromraw /dev/sdb my_new_virtual_drive.vdi --format VDI
Done. I’ve used this with windows and Linux (Mint) disks, all worked fine for me.

Subject: Re: replacing Windows w/ Linux
I have converted several windows 7 and windows 2012 servers to proxmox kvm by using clonezilla (helps to add the kvm driver first)
For virtualbox I have used a vmware converter with success but I hear that Disksvhd is better.
I added a youtube video that shows the basic process.
time factor will be based on speed and drive size and after the process recheck the MS license depending on the windows version you may need to update the license as if you upgraded the hardware
