I managed to dual-boot my computer which has Windows 7 with Windows 8. I have tried Windows 8 a few months ago though. By the way, my Windows 7 is a home premium, this is why, there is no BitLocker.
However, with Windows 8, I use Windows 8 pro, this feature is included. What is BitLocker? BitLocker Drive Encryption is basically protecting your drive, which I do it with a password.
Read more about BitLocker in this Wikipedia for more technical explanation.
There are obviously many ways to access the BitLocker settings and I will show you how to get there in two ways. (Due to my learning process with Windows 8 :-))
2 Options To Turn BitLocker On
Option #1. (The easiest)
1. Press your Windows key on your keyboard, it’s the key which has “Windows” label. Now, you should be in start screen. Right click anywhere in empty space, you should see a small round icon, which says, “all apps”. Click it.
2. Look for “File Explorer“, if you don’t see it, scroll to the right, until you find it. Once you do, click “File Explorer” icon.
Alternatively to find, “File Explorer”, hover your mouse in the very left bottom corner of your screen (where the old start Windows was located) then right click, and select, “File Explorer”.
3. Click any drive you want to activate BitLocker.
4. For this tutorial, I choose Hard drive, “F”. In the new ribbon menu at the top, “Drive tools” which is green highlighted in my system, click that, and then click, “Manage”. You will see the “BitLocker” icon at the very left of the menu. Click the small arrow under this icon.
5. I don’t know in your system, but I got this error message,
“This device cannot use a Trusted Platform Module. Your administrator must set the “Allow BitLocker without a compatible TPM” option in the “Require additional authentication at start-up” policy for OS volumes.”
If you have this too, then click cancel.
6. Now we must go to “Edit Group Policy” first. To get there, hover your left bottom screen again, until you see Start screen thumbnail, right click, and select, “Control Panel”.
7. Then, in Control Panel dialog box, type, “group policy”. You will see “Edit Group Policy” in “Adminitrative Tools” results.
8. Now, in “Local Group Policy Editor”, look for “Administrative Templates” in the drop down, and click the little arrow next to it, you will see “Windows Components“, click its little arrow.
9. Scroll down, you will see “BitLocker Drive Encryption” click the little arrow.
10. Then click “Operating System Drives“, you will see “Require additional authentication at startup”, select it, and right click it, select “edit”.
11. In this dialog box, see this screenshot, click on “Enabled” and Apply, and OK. Close all Windows except File Explorer.
12. Back to File Explorer, select a drive, go to “Drive Tools, “Manage”, “Turn BitLocker On”
13. You will see then the BitLocker windows and it will ask you how to protect your drive, either inserting a USB or typing password. Choose wisely.
In this tutorial, I use, “Enter a password”.
14. Enter your password. Then click Next.
15. Choose how to backup your recovery key. I choose, save to a USB flash drive. Click “Next”
16. It will ask, how much of our drives we want to encrypt. Read them, and choose carefully too. In this tutorial I use the default setting, because my computer is relatively new.
17. It will then ask you, “Are you ready to encrypt this drive” if you do, click “continue” button.
18. Now, it asks you to restart your computer, best to follow it.
Basically, now it will restart your computer, and before you see your start screen again, you need to enter your password that you just typed earlier.
If you choose, the whole drives (in step 16), it will then showing you that BitLocker is doing the encryption, and you can see it in this dialog box. But if you choose the fast process, you are done.
1. Win+C press these keys together at the same time, and you will see charms bar, click on search icon.
2. Click in Settings, and then type in “Bitlocker” in search.
3. Click on “BitLocker Drive Encryption” in the left area of your start screen.
4. Now you can see, drives you can protect with BitLocker.
5. Click on “turn BitLocker on”
6. If you have error, go to step no 6 above in the option no. 1 above.
If you don’t have the error, follow step no 13 Option no 1 above.
That’s all actually, it’s so easy, backup your recovery key wisely!.
