At the Startup Options screen, you will have three options to choose from (see Figure.1):
One way to start Windows 8 in Windows Recovery Environment is to simply press SHIFT and then click on Restart. What’s good about this method is that you can do it from within Windows, or you can do it even if no one is logged onto the system.
So if you need to troubleshoot a Windows 8 machine or boot from a secondary device and you can’t log into the system, then you can still restart in Windows RE by clicking on the power button icon at the bottom right of the login screen.
The second way to do it is to go to PC Settings in Windows 8. You can do that by opening the Charms bar and then clicking on Settings.
Then click on Change PC Settings at the bottom of the settings bar:
Finally, click on General and then click on Restart now under the Advanced startup section.
Lastly, if Windows 8 detects any boot problem with the system, it will automatically load up Windows RE boot options.
If your board supports the new UEFI firmware, this will happen automatically. If not, you would still need to press the F8 key, but you will not have a lot of time since Windows 8 loads so much faster.
Instead, the best way would be to use Methods 1 or 2. However, if you cannot boot into Windows 8 at all, and the boot options do not come up automatically, you’ll have to hope you created a Windows 8 USB Recovery Drive. A recovery drive in Windows 8 will basically let you create a bootable USB flash drive that will load the Windows RE environment in case it won’t load automatically and you can’t get into Windows.
When you see the Dell Logo and the Windows 8 Circling dots, Hold the power button down until system shuts off.
Perform this procedure 3 times.
