If you're an OCD type of person, and you want your Boot mode to run back in
"Normal" mode, that might require a Windows reset or more likely a complete Windows reinstallation from
Factory Recovery Media discs. This might require that you make those discs, and if you are on a tablet that means you'll have to buy an external usb dvd writer to do so. You can buy one here on Amazon:

Another way to go, is to simply purchase the Factory Recovery Media (DVD discs or USB stick) directly from the computer manufacturer. Some companies such as Dell, HP, and now Toshiba, allow you to order the Media online with a Credit Card. I just did this with a Toshiba C855 a couple of weeks ago; and of course since it's from Toshiba, it worked flawlessly!
Others will require you to make a phone call to their Tech Support.
Cost is $29-$99 US. Assuming that you're hard drive hasn't failed, this will take care of that problem. If you prefer to do your own hardware testing first, which is a good idea since tablets, as laptops and cell phones do take a beating, especially with inadvertent drops, here's a link to do that:
