Clonezilla

You can use this method to clone a physical machine to another physical machine, or migrate a VMware ESXi VM to Proxmox...

Please note that Clonezilla cannot restore to a smaller disk; you must have a destination disk of the same size or larger.

If the source machine uses UEFI mode, the target machine must also be configured in UEFI mode.

Similarly, if the source machine is running in Legacy mode, the target machine must also be in Legacy mode.

This method works for both Windows and Linux, as long as Linux can properly see the disk.
