How to virtualize Win10 from Linux (into VirtualBox on Linux) and shrink it?

Basically, what I need could be similar to what most other people running Windows for work would want, I suppose, so let us get started on my requirements: 1. Somehow copy a raw disk (e.g. /dev/sda) onto a bigger medium. In my case, Windows is stored on a 1TB SATA SSD and I want to clone it into the VirtualBox VDI format and store it onto my bigger NVMe SSD medium which has about 1.5TB of free space. 2. After making proper adjustments to the VirtualBox VM settings, start the VM up. 3. Free as much of the VM's disk space as possible, such as uninstalling games, etc.. which are irrelevant to the VM's use case. 4. Then, shrink the VM's disk to the minimum (used space only).
