Note:

  • If the partition resizing process involves operating system, DiskGenius will prompts to enter DOS version to complete the task. If your operating system does not support DOS system anymore, you can enter DiskGenius WinPE version to resize system partition.
  • Please do not access the partition being resized in case of any unexpected issues.
  • The resizing process may take long time if there are too many files on the partition. In that case, you can set operations after resizing finishes.
  • Partition resizing may fail to complete or even cause data loss due to hard drive or partition errors, bad sectors, sudden power failure or system errors. Thus resizing partition is a risky action to some extent and data backup is necessary.
