Note: These instructions are focused on Windows 7. However, the process is very similar for Windows 8 and 10 as well.
When rebooting your system, if you are asked to choose between WipeDrive or Windows from the Boot Manager screen, simply choose Windows. The software should then be uninstalled upon boot-up, and the selection should be removed the next time you reboot your system.
If, however, you have rebooted the machine multiple times, and the Windows Boot Manager is still asking for you to choose between Windows 7 and WipeDrive, follow these instructions to remove it manually:
Warning: Please follow these instructions carefully. If the selection for "Windows" is removed instead of the selection for "WipeDrive", you will not be able to access Windows any more, and will need to use a repair or re-installation CD to use Windows again.
1) Click here, then click Register under 'Non-commercial' on that page. After clicking Register, you will be prompted for your name and e-mail. You don't have to enter that information if you don't want to, however, if you do, the developers of the software would use it to keep you informed of any newer versions that they release. These new versions may include bugfixes, and ways to prevent the user from accidentally removing Windows entirely. Click Download to begin downloading the software.
2) Run the downloaded installation file and proceed with installation. If you're unsure of any option during installation, simply click Next or OK.
5) Make sure to select Windows as the default boot option, the Timeout Options are set to Skip the boot menu, and that you click the Save Settings button when finished. Failure to set these may keep the default boot setting as WipeDrive, but erase Windows, making it almost impossible to load Windows after you reboot the system.
