How to? -steps
Erase files and folders
Note: The default overwriting method is zero-filling, you can try other Simple Overwrite methods (Recommended) or multiple overwriting standards (depend on your needs).
Erase Free Space
Erase Entire Drive
Note: Please Do remember to check out and backup the important data on the drives, because when ByebyeData Eraser starts to work, nothing can be recovered from the selected items.
Erase Entire Disk
Note: When you select the boot disk to erase, you're about to erase everything on the disk, including the operating system. If you want to install the OS, please make sure you have the installation CD or USB, since all the restore points are too erased.
Create Bootable Media
Tips: After created the ISO file, you can burn it to CD or USB. CD burning requires no third party software; double-click to run and Windows default tool will show up; USB burning, on the other hand, we recommend Rufus.
