By design, Windows 8/RT does not support pre-boot diagnostics or a BIOS option. However, there is a recovery mode.
Before attempting a system recovery, ensure that the system is charged and is not in a hung state by pressing and holding the power button for 10+ seconds, then attempt to boot the device by pressing the power button for 2-3 seconds. If it will not boot, press and hold the power button for 10+ seconds to ensure that it is off.
- Hold the volume-up button and then press the power button for 2-3 seconds.

Once completed, the customer will have to go through the Windows initial setup sequence again. Refreshing the device will maintain the customer's files and settings while attempting to clean problems with the operating system. Refresh can take 30+ minutes to complete.
