To free copy a partition to another disk in Windows 10 without data loss, you'll need to use third-party disk cloning or imaging software, as Windows 10 doesn't have a built-in feature for this purpose. Here's a straightforward approach:
1. Choose a Reliable Cloning Tool:
- Popular free options or tools for safe disk cloning.
2. Prepare Your Hardware:
- Connect the new disk to your PC via a USB-to-SATA adapter, external enclosure, or directly inside your PC if possible.
3. Backup Important Data:
- Before proceeding, back up critical files to prevent any accidental data loss during the process.
4. Clone the Partition:
- To copy a partition to another disk. Open the chosen software and select the partition you want to copy. Then, select the target disk as the destination.
- Follow the software’s prompts to start the cloning process. This usually involves a few clicks and some confirmation steps.
5. Verify the Clone:
- Once complete, check that the cloned partition appears correctly on the new disk. You can use Disk Management to see the new partition.
6. Boot from the New Disk:
- If you want to make the new disk bootable (e.g., clone your OS), ensure the clone is an exact copy of your system drive, and then change your BIOS settings to boot from the new disk.
