Acronis True Image OEM
Acronis True Image OEM provides a hidden but accessible image on the hard drive of the controller.
During system boot, press the Delete key during BIOS post. Then you will be prompted to press F4, and then you can enter the Acronis utility to reinstall from this original image. The Acronis utility included with Windows also provides the ability to create custom backups and locate them on external USB or other attached media. Upon running the Windows Acronis program for the first time, you will be prompted to upgrade to the full version to enable features such as network backups, incremental backups, and more. This functionality is optional and is not supported by National Instruments.
Phoenix Firstware is used to store a factory image of your hard drive in an inaccessible area of the drive. By changing the reported size of the disk drive, the Firstware area is hidden so other activity on the disk (including full formats) does not remove it. By tapping the F4 or Alt keys when booting, you will see the option to recover your hard drive from this original image. For more information, reference your controller's user manual.
Images Directory (Obsolete)
In older controllers, the C:\images directory was used to store the software to reinstall the OS on the controller. This method is no longer used on PXI, VXI, cRIO-908x, or cDAQ-913x controllers.
