\n\tAs you may have noticed, Microsoft has disabled the standard method of accessing Safe Mode in Windows 8 in favor of a new Modern UI system. In other words, you can no longer press F8 during the Windows start up sequence and access the black and white Advanced Boot Options menu system from which you can select Safe Mode. Microsoft’s justification for disabling the F8 key is essentially that computers boot up so fast these days that people will have trouble pressing F8 before Windows starts.
\n
\n\tI suppose that if you are running Windows 8 on a SSD-based UEFI system where as Microsoft says the F8 window is less than 200 milliseconds, you won’t be able to use F8 to get to Safe Mode. However, on my test systems, which are not UEFI and running on SATA drives, I definitely have time to press F8 and I’ll bet that a lot of you do too. Fortunately, there is a way that you can re-enable the F8 key and revive the good old black and white Safe Mode menu system.
\n
\n
\n\tNow if you do in fact have a system that boots way too fast to be able to access Safe Mode with the F8 key, then Microsoft states that when there is a boot problem, the system will automatically allow you to get to the Startup Settings menu where you can then access all the available Safe Mode options. In addition, you can access Safe Mode from within Windows by accessing a series of menus and commands in the Modern UI.
\n
\n\tI’ll show you how to reconfigure Windows 8’s boot process to allow you to use the F8 key to access the black and white Advanced Boot Options menu of old. However, before I do, I’ll show you how access Safe Mode options from the Modern UI’s Startup Settings menu-just in case you want to know. As I do, I’ll describe both the old and new options on the Safe Mode system..
\n
\n
\n\tAs you can image, the Modern UI method involves a menu system very similar to the Windows Recovery Environment that I have described in a recent series of articles. However, you can’t access Safe Mode from the Recovery Drive – instead you access it from within Windows 8. Let’s take a closer look.
\n
\n\tTo begin, press [Windows]+C to access Charms bar. When you see the Charms bar, click Settings as shown in Figure A.

\n\tOn the PC settings screen, choose General from the menu bar, scroll down to Advanced Startup, and then click Restart now button, as shown in Figure C. When you do, your Windows 8 system will reboot into the Recovery Environment.

\n
\n\tWhen you see the Troubleshoot screen, as shown in Figure E, select the Advanced options tile.

\n\tIn a moment you’ll see the Advanced options screen, as shown in Figure F. When you do, select the Startup Settings tile. (Note that when you boot from a Recovery Drive, the Advanced options screen does not contain the Startup Settings tile.)

\n\t
\n
\n\tOnce you do, you will see the Startup Settings window like the one shown in Figure G, which informs you what options you will be able to change in the Safe Mode environment. To continue, click the Restart button and the system will reboot into the Safe Mode Environment.

\n
\n\tWhen you use the Modern UI method to access Safe Mode, you’ll see a menu titled Startup Settings, as shown in Figure H. As you can see there are nine options on this menu that can be accessed by pressing the corresponding number key or by using the corresponding function key. You can also press F10 to access one more item or press [Enter] to start Windows normally.

\n\tWhen you press F10, you’ll see the additional item on the menu, as shown in Figure I. You can then press F10 again to return to the first menu or you can press [Enter] to start Windows normally.
\n

\n
\n\tTable A lists and describes each of the options on the Startup Settings menu.
\n
\n
| \n\t\t\t\t
\n\t\t\t\t\tMenu Option \n\t\t\t |
\n\t\t\t\t
\n\t\t\t\t\tDescription \n\t\t\t |
| \n\t\t\t\t
\n\t\t\t\t\tEnable debugging \n\t\t\t |
\n\t\t\t\t
\n\t\t\t\t\tThis option enables kernel debug mode in Windows. Debug mode is primarily of use to developers creating drivers for the operating system. You can learn more on Microsoft’s Dev Center site. \n\t\t\t |
| \n\t\t\t\t
\n\t\t\t\t\tEnabled boot logging \n\t\t\t |
\n\t\t\t\t
\n\t\t\t\t\tThis option enables logging when the computer is started with any of the Safe Boot options. The Boot Logging information is written to a file called Ntbtlog.txt, which can be found in the %SystemRoot% folder. The data in this file is designed to help you determine the cause of problems, such as starting a driver or other boot process errors. \n\t\t\t |
| \n\t\t\t\t
\n\t\t\t\t\tEnable low-resolution video \n\t\t\t |
\n\t\t\t\t
\n\t\t\t\t\tThis option starts Windows in a low resolution mode, typically 640 x 480. This mode is useful if the resolution is inadvertently configured for a setting that the monitor cannot properly display. \n\t\t\t |
| \n\t\t\t\t
\n\t\t\t\t\tEnable Safe Mode \n\t\t\t |
\n\t\t\t\t
\n\t\t\t\t\tThis option enables basic Safe Mode, which provides a minimal set of device drivers and services necessary to start Windows. \n\t\t\t |
| \n\t\t\t\t
\n\t\t\t\t\tEnable Safe Mode with Networking \n\t\t\t |
\n\t\t\t\t
\n\t\t\t\t\tThis option enables Safe Mode along with the drivers required to load networking. \n\t\t\t |
| \n\t\t\t\t
\n\t\t\t\t\tEnable Safe Mode with Command Prompt \n\t\t\t |
\n\t\t\t\t
\n\t\t\t\t\tThis option basically works the same as Safe Mode, except that it displays a Command Prompt window rather than the Safe Mode desktop \n\t\t\t |
| \n\t\t\t\t
\n\t\t\t\t\tDisable driver signature enforcement \n\t\t\t |
\n\t\t\t\t
\n\t\t\t\t\tAs you may know, Windows doesn’t allow any drivers to load if they haven’t been digitally signed with a signature that verifies the company it belongs to. Disabling this feature allows drivers that aren’t signed to load, which could allow malware loaded drivers access to your system. Again, this might be more appropriate for use by developers creating drivers for the operating system. \n\t\t\t |
| \n\t\t\t\t
\n\t\t\t\t\tDisable early launch anti-malware protections \n\t\t\t |
\n\t\t\t\t
\n\t\t\t\t\tThe early launch anti-malware protection feature is new with Windows 8 and is designed to allow certified anti-virus software to load a driver before any other 3rd-party driver is installed. This allows the anti-virus software to scan every driver that attempts to load. If a driver appears to be malware infected, it will block it from loading. This feature really shouldn’t be disabled unless you are certain that a driver conflict is preventing Windows from starting. \n\t\t\t |
| \n\t\t\t\t
\n\t\t\t\t\tDisable automatic restart after failure \n\t\t\t |
\n\t\t\t\t
\n\t\t\t\t\tIf windows encounters problem that causes the operating system to crash, it will display an error message and then automatically restart. In some cases that can cause a problem and you might want to disable it. For instance, the system may restart before you can read the entire error message. Or, the system could enter an endless loop where in crashes and then restarts over and over again. \n\t\t\t |
| \n\t\t\t\t
\n\t\t\t\t\tLaunch recovery environment \n\t\t\t |
\n\t\t\t\t
\n\t\t\t\t\tSelecting this option simply returns you to the Windows Recovery Environment where you can use any of the other recovery tools such as Refresh your PC. \n\t\t\t |

\n\tTo revive the F8 method of accessing the Safe mode, you begin from within Windows 8 by pressing the [Windows]+X keystroke to bring up the WinX menu, Then select the Command Prompt (Admin), as shown in Figure J. You’ll then encounter a UAC and will need to respond appropriately.

\n\t
\n
\n\tWhen the Administrator: Command Prompt window appears, type the command and press [Enter].
\n
\n\tbcdedit /set {default} bootmenupolicy legacy
\n
\n\tWhen you do, you should see the message The operation completed successfully, as shown in Figure K.
\n
\n\tCredit: Images by Greg Shultz for TechRepublic
\n\tThis command line launches the Boot Configuration Data Editor and sets the default boot menu policy to legacy i.e. back to the way it was in Windows 7 and previous versions of Windows. Now, you can close the Administrator: Command Prompt and restart Windows 8. When you see the blue windows flag appear on the screen for the first time, press and hold down the F8 key. In a moment you should see the old black and white Advanced Boot options menu, as shown in Figure L.
\n
\n\tIf at a later date you would like to disable the F8 key and go back to the original Windows 8 setting, you can launch the Administrator: Command Prompt window and type the command
\n
\n\tbcdedit /set {default} bootmenupolicy standard

\n
\n\tWhen you select one of the Safe Mode options, your system will restart and you’ll be prompted to login. When you do, the option you selected will be enabled. For example, if you select that standard Safe Mode, you will see a screen like the one shown in Figure M.
\n

\n
\n\tBefore I conclude this article, there is one more method that you can use to boot Windows 8 into Safe Mode from within the operating system. This method works just like it did in Windows 7.
\n
\n\tTo access it, press [Windows]+R to bring up the Run dialog box, type msconfig and click OK. When you see the System Configuration window, select the Boot tab. Then, in the Boot options section, select the Safe Boot check box, and then one of the available options, as shown in Figure N.
\n

\n\tWhen you click OK, the system will prompt you to restart, as shown in Figure O. When you click the Restart button, the system will then reboot straight into the Safe mode option you selected.
\n
\n
\n\tHave you had to use Safe Mode in Windows 8? Did it come up automatically as Microsoft stated? Will you revive the F8 method of accessing Safe Mode?

My first computer was a Kaypro 16 \"luggable\" running MS-DOS 2.11 which I obtained while studying computer science in 1986. After two years, I discovered that I had a knack for writing documentation and shifted my focus over to technical writing.
