Step 4: Start the computer from the startup U disk and enter the Renee PassNow program. Select the (data backup) option, which clones the hard disk to other hard disks. Ensure that the capacity of the backup disk is larger.

Step 5: Choose the source hard disk from the list, select the destination hard disk, and click "clone". Wait for the cloning process to finish to successfully backup the computer’s hard disk files.

Step 6: If you only need to transfer some important data to the hard disk, you can choose (Data Transfer).

Step 7: Click on each disk drive letter (C/D/E/F, etc.) to find files for transfer. It is recommended to transfer them to an external disk. Transferring data is simple. For example, to transfer data from C drive to G drive, select C drive on the upper left, select G drive on the upper right, select files in C drive, and press the Copy button in the middle to easily transfer disk data. To delete a file, select it and click the Delete button in the middle, but note that deletion cannot be undone, so proceed with caution.

Tip: If any files are lost during backup or data transfer, use the (Undeleter) option on the main interface for data recovery.

After safely backing up or transferring the data, you can confidently proceed with the repair operations.
