How to start Windows in Safe Mode

Introduction

Windows Safe Mode is a way of booting up your Windows operating system in order to run administrative and diagnostic tasks on your installation. When you boot into Safe Mode the operating system only loads the bare minimum of software that is required for the operating system to work. This mode of operating is designed to let you troubleshoot and run diagnostics on your computer. Windows Safe Mode loads a basic video drivers so your programs may look different than normal.

For Win98/ME, XP, Vista and Windows 7 there are two methods of booting into Safe Mode, while 95 and 2000 only have one. We will describe these methods below:





F8 - By pressing the F8 key right when Windows starts, usually right after you hear your computer beep when you reboot it, you will be brought to a menu where you can choose to boot into safe mode. If it does not work on the first try, reboot and try again as you have to be quick when you press it. I have found that during boot up right after the computer shows you all the equipment , memory, etc installed on your computer, if you start lightly tapping the F8 key you will usually be able to get to the desired menu.

System Configuration Utility - You can use the System Configuration Utility, or MSCONFIG, found in Windows 98, ME, XP, Windows Vista, and Windows 7 to make Windows boot into Safe Mode on the next reboot. We will go into specific details in the sections below. Please note, that you should not force your computer to boot into Safe Mode using the System Configuration Utility if you suspect you are infected with malware as the malware may corrupt keys required to boot into Safe Mode. You can read more about this here.

Windows 95

Windows 95 can only boot into Safe Mode using the F8 method as it does not have a System Configuration Utility.

Using the F8 Method:
1.Restart your computer.
2.When the machine first starts it will generally list some equipment that is installed in your machine, amount of memory, hard drives installed etc. When it is finished with that it will say "Starting Windows 95". Immediately after seeing "Starting Windows 95" press the F8 key.
3.You will now be presented with a menu. Select the option for Safe Mode using the arrow keys.
4.Then press enter on your keyboard to boot into Safe Mode.
5.Do whatever tasks you require and when you are done reboot to boot back into normal mode.

Windows 98/ME

NOTE: Windows ME may look slightly different than what is shown in the images below. You should still have no problem following along.




Using the F8 Method:
1.Restart your computer.
2.When the machine first starts again it will generally list some equipment that is installed in your machine, amount of memory, hard drives installed etc. At this point you should gently tap the F8 key repeatedly until you are presented with a menu.
3.When you have the menu on the screen. Select the option for Safe Mode using the arrow keys.
4.Then press enter on your keyboard to boot into Safe Mode.

Problems that can occur by forcing Safe Mode using the System Configuration Utility

It is possible to make your computer continuously boot up into safe mode using the System Configuration utility as described above. The program does this by changing your boot.ini file, the settings file that configures your computer's boot sequence, and adding the /safeboot argument to your operating systems startup line. An example of this can be seen below.



Original [operating systems]
multi(0)disk(0)rdisk(0)partition(2)\WINDOWS="Micro soft Windows XP Professional" /FASTDETECT /NOEXECUTE=OPTIN
After using MsConfig.exe [operating systems]
multi(0)disk(0)rdisk(0)partition(2)\WINDOWS="Micro soft Windows XP Professional" /FASTDETECT /NOEXECUTE=OPTIN /safeboot:minimal

When you are done using safe mode, you would then run the System Configuration utility again and uncheck the /Safeboot option, thus removing the /safeboot argument from the boot.ini file, and allowing your computer to boot up normally.

On a computer that is operating properly this is normally not a problem. Unfortunately, though, a new trick that some of the more recent malware are using is to delete certain Windows Registry keys so that your computer can not properly boot into safe mode. It is in these situations that using the System Configuration utility to boot into safe mode can cause the computer to become inoperable for many users.

This is because once you set the computer to boot into Safe Mode using /Safeboot, it will continuously attempt to start Safe Mode until the /safeboot argument is removed from the boot.ini. Since the malware is not allowing us to actually boot into safe mode, you have no way of getting to a point where you can run the System Configuration utility again to uncheck the /Safeboot option. Thus, you are stuck with a computer constantly attempting to get into safe mode and not being able to do so.

If a situation like this has happened to you it is possible to fix this problem by renaming your boot.ini file. The first step would be to use a boot disk to start your computer. If your computer does not have a floppy disk, then you can typically boot off the Windows CD that came with your computer in order to access the Windows Recovery Console. More information about the Windows Recovery Console can be found here. Once booted to a command prompt, you would simply rename your C:\Boot.ini file to another name like C:\Boot.ini.bak. The command to rename the file at the command prompt is:

ren C:\Boot.ini Boot.ini.bak

Once the file is renamed, you can then remove the boot disk and reboot your computer to get back to normal mode. When booting up after the rename, do not be surprised if you see an error stating that you do not have a valid Boot.ini file. When you get back to normal Windows mode, you can then rename C:\Boot.ini.bak to C:\Boot.ini and run Msconfig again to remove the /safeboot flag.



Conclusion

It is not uncommon when people are helping you troubleshoot your computer that they tell you to enter Safe Mode. With this tutorial you should now know how to enter Safe Mode when it is required.
