How to do System Clone or System Migration?

WinToHDD can help you to clone your current Windows OS installation (Windows vista or later) to another disk (HDD/SSD). As its name implies, the system clone means to make an exact copy of the original operating system to another storage device such as a hard disk drive (HDD) or a solid state drive (SSD). It not only copies the operating system files, but also the installed applications and other custom settings, so you don't need to reinstall the applications and reconfigure the operating system after cloning.


Using WinToHDD to clone your current Windows OS installation to another disk:
  1. Click to open the WinToHDD installation file. Follow the steps in the setup dialogs. You'll have the option to specify where to install WinToHDD.
  2. Please use the following guidelines to prepare the partitions on the destination hard disk drive.
    • Booting BIOS-based computers: Please covert the USB drive to MBR partition scheme and create the system and boot partitions. The system partition can be FAT32 or NTFS format and the boot partition must be NTFS format. The system partition and boot partition can be the same partition.
    • Booting UEFI-based computers: Please covert the USB drive to GPT partition scheme and create the EFI system partition (ESP) and boot partition. The EFI system partition must be FAT32 format and the boot partition must be NTFS format.
    1. The destination boot partition must be 20% larger than the used space on source boot partition.
    2. If the destination system partition is FAT32 format, then it must be greater than or equal to 40 MB and less than or equal to 32 GB.
    3. Sector by sector clone option enables you to clone all sectors from source boot partition to destination boot partition.
