To do this, you need to go into your system settings, select memory, and then select the hard disk symbol. Once you are in the hard disk menu, you need to press these buttons in sequence: X X Left Right X X. A message will pop up asking you whether you want to perform system maintenance on your storage devices. Select yes.

Continue holding it until the console is completely booted and the dashboard appears. The console would’ve automatically cleared any failed system updates during the boot process.
If the E79 error code still appears on your screen despite all the steps outlined above, then you need to replace your Xbox 360’s hard drive with a working model.
