⚠️ Important Note Before Beginning:
Disk partitioning involves structural changes to your hard drive. While EaseUS is a reputable tool, there is always a risk of data loss due to power failure, software crashes, or hardware errors. Always back up your critical data to an external drive or cloud storage before performing any partition operations.
