Advanced startup options (including safe mode)

The Advanced Boot Options screen lets you start Windows in advanced troubleshooting modes. You can access the menu by turning on your computer and pressing the F8 key before Windows starts.

Some options, such as safe mode, start Windows in a limited state, where only the bare essentials are started. If a problem doesn’t reappear when you start in safe mode, you can eliminate the default settings and basic device drivers and services as possible causes. Other options start Windows with advanced features intended for use by system administrators and IT professionals. For more information, go to the Microsoft website for IT professionals.

Repair Your Computer

Shows a list of system recovery tools you can use to repair startup problems, run diagnostics, or restore your system. This option is available only if the tools are installed on your computer’s hard disk. If you have a Windows installation disc, the system recovery tools are located on that disc.

Safe Mode

Starts Windows with a minimal set of drivers and services.

To start in safe mode:

Remove all floppy disks, CDs, and DVDs from your computer, and then restart your computer. Click the Start button , click the arrow next to the Shut Down button (or the arrow next to the Lock button), and then click Restart.

Do one of the following:

If your computer has a single operating system installed, press and hold the F8 key as your computer restarts. You need to press F8 before the Windows logo appears. If the Windows logo appears, you’ll need to try again by waiting until the Windows logon prompt appears, and then shutting down and restarting your computer.

If your computer has more than one operating system, use the arrow keys to highlight the operating system you want to start in safe mode, and then press F8.

On the Advanced Boot Options screen, use the arrow keys to highlight the safe mode option you want, and then press Enter.

Log on to your computer with a user account that has administrator rights.

Safe Mode with Networking. Starts Windows in safe mode and includes the network drivers and services needed to access the Internet or other computers on your network.

Safe Mode with Command Prompt. Starts Windows in safe mode with a command prompt window instead of the usual Windows interface. This option is intended for IT professionals and administrators.

Enable Boot Logging. Creates a file, ntbtlog.txt, that lists all the drivers that are installed during startup and that might be useful for advanced troubleshooting.

Enable low-resolution video (640×480). Starts Windows using your current video driver and using low resolution and refresh rate settings. You can use this mode to reset your display settings. For more information, see Change your screen resolution.

Last Known Good Configuration (advanced). Starts Windows with the last registry and driver configuration that worked successfully.

Directory Services Restore Mode. Starts Windows domain controller running Active Directory so that the directory service can be restored. This option is intended for IT professionals and administrators.

Debugging Mode. Starts Windows in an advanced troubleshooting mode intended for IT professionals and system administrators.

Disable automatic restart on system failure. Prevents Windows from automatically restarting if an error causes Windows to fail. Choose this option only if Windows is stuck in a loop where Windows fails, attempts to restart, and fails again repeatedly.

Disable Driver Signature Enforcement. Allows drivers containing improper signatures to be installed.

Start Windows Normally. Starts Windows in its normal mode.

How to refresh, reset, or restore your PC

Note: For information about this topic in Windows 10, see Recovery options in Windows 10.

If you’re having problems with your PC, you can:

Refresh your PC to reinstall Windows and keep your personal files and settings. Refresh also keeps the apps that came with your PC and the apps you installed from the Microsoft Store.

Reset your PC to reinstall Windows but delete your files, settings, and apps—except for the apps that came with your PC.

Restore your PC to undo recent system changes you’ve made.

If you’re having trouble starting (booting) your PC, see Windows Startup Settings (including safe mode), and go to the “Get to Windows Startup Settings in the Windows Recovery Environment” section. You can refresh, reset, or restore your PC from the Windows Recovery Environment.

If you want to back up and restore your personal files using File History, see Set up a drive for File History.

Before you start to refresh or reset your PC

In most cases, once you start to refresh or reset your PC, it’ll finish on its own. However, if Windows needs missing files, you’ll be asked to insert recovery media, which is typically on a DVD disc or thumb drive. If that happens, what you’ll need depends on your PC.

If your PC came with Windows 8.1 or Windows RT 8.1, you’ll need the discs or thumb drive that came with your PC. Check the info that came with your PC to see if your PC manufacturer provided these discs or media. In some cases, you might have created them when you first set up your PC.

If you don’t have either of those, you can make them if you have a USB thumb drive of 16 GB or larger. Having a recovery drive can help you troubleshoot and fix problems with your PC, even if it won’t start. For more info, see Create a USB recovery drive.

If you upgraded your PC to Windows 8.1 or Windows RT 8.1 with a DVD, use that disc. If you don’t have Windows 8.1 or Windows RT 8.1 media, contact Microsoft Support.

Refresh, reset, or restore

Select any of the following for more detailed info.

If your PC isn’t performing as well as it once did, and you don’t know why, you can refresh your PC without deleting any of your personal files or changing your settings.

Note: If you upgraded your PC from Windows 8 to Windows 8.1 and your PC has a Windows 8 recovery partition, refreshing your PC will restore Windows 8. You’ll need to upgrade to Windows 8.1 after the refresh has finished.

Warning: Apps you installed from websites and DVDs will be removed. Apps that came with your PC and apps you installed from Microsoft Store will be reinstalled. Windows puts a list of removed apps on your desktop after refreshing your PC.

To refresh your PC

Swipe in from the right edge of the screen, tap Settings, and then tap Change PC settings.
(If you’re using a mouse, point to the upper-right corner of the screen, move the mouse pointer down, click Settings, and then click Change PC settings.)

Tap or click Update and recovery, and then tap or click Recovery.

Under Refresh your PC without affecting your files, tap or click Get started.

Follow the instructions on the screen.

If you want to recycle your PC, give it away, or start over with it, you can reset it completely. This removes everything and reinstalls Windows.

Note: If you upgraded your PC from Windows 8 to Windows 8.1 and your PC has a Windows 8 recovery partition, resetting your PC will restore Windows 8. You’ll need to upgrade to Windows 8.1 after the reset has finished.

Warning: All of your personal files will be deleted and your settings will be reset. All apps that you installed will be removed. Only apps that came with your PC will be reinstalled.

To reset your PC

Swipe in from the right edge of the screen, tap Settings, and then tap Change PC settings.
(If you’re using a mouse, point to the upper-right corner of the screen, move the mouse pointer down, click Settings, and then click Change PC settings.)

Tap or click Update and recovery, and then tap or click Recovery.

Under Remove everything and reinstall Windows, tap or click Get started.

Follow the instructions on the screen.

Note: You’ll be asked to choose whether you want to erase data quickly or thoroughly. If you choose to erase data quickly, some data might be recoverable using special software. If you choose to erase data thoroughly, this will take longer but it makes recovering data less likely.

If you think an app or driver that you recently installed caused problems with your PC, you can restore Windows back to an earlier point in time, called a restore point. System Restore doesn’t change your personal files, but it might remove recently installed apps and drivers.

System Restore isn’t available for Windows RT 8.1.

Windows automatically creates a restore point when you install desktop apps and new Windows updates, if the last restore point is older than 7 days. You can also create a restore point manually at any time.

To restore your PC to an earlier point in time

Swipe in from the right edge of the screen, and then tap Search.
(If you’re using a mouse, point to the upper-right corner of the screen, move the mouse pointer down, and then click Search.)

Enter Control Panel in the search box, and tap or click Control Panel.

Enter Recovery in the Control Panel search box, and then tap or click Recovery.

Tap or click Open System Restore, and then follow the instructions.

If you need additional help refreshing, resetting, or restoring your PC, check out the Repair and Recovery community pages in the Windows forum for solutions that other people have found for problems they’ve experienced.

What are the system recovery options in Windows?

Support for Windows 7 ended on January 14, 2020

We recommend you move to a Windows 10 PC to continue to receive security updates from Microsoft.

The System Recovery Options menu contains several tools, such as Startup Repair, that can help you recover Windows from a serious error. This set of tools is on your computer’s hard disk and on the Windows installation disc.

Note: You can also create a system repair disc that contains the System Recovery Options menu. For more information, see Create a system repair disc. If you use a Tablet PC or other computer with a touchscreen, you might need to connect a keyboard and mouse in order to use Startup Repair and the other tools in the System Recovery Options menu.

What each recovery option does

System recovery option

Fixes certain problems, such as missing or damaged system files, that might prevent Windows from starting correctly.

Restores your computer’s system files to an earlier point in time without affecting your files, such as e‑mail, documents, or photos.

If you use System Restore from the System Recovery Options menu, you cannot undo the restore operation. However, you can run System Restore again and choose a different restore point, if one exists.

System Image Recovery

You need to have created a system image beforehand to use this option. A system image is a personalized backup of the partition that contains Windows, and includes programs and user data, like documents, pictures, and music.

Windows Memory Diagnostic Tool

Scans your computer’s memory for errors.

Advanced users can use Command Prompt to perform recovery-related operations and also run other command line tools for diagnosing and troubleshooting problems.

Note: Some computer manufacturers might customize the menu by adding or removing recovery tools, or including their own tools.

To open the System Recovery Options menu on your computer

Remove all floppy disks, CDs, and DVDs from your computer, and then restart your computer using the computer’s power button.

Do one of the following:

If your computer has a single operating system installed, press and hold the F8 key as your computer restarts. You need to press F8 before the Windows logo appears. If the Windows logo appears, you need to try again by waiting until the Windows logon prompt appears, and then shutting down and restarting your computer.

If your computer has more than one operating system, use the arrow keys to highlight the operating system you want to repair, and then press and hold F8.

On the Advanced Boot Options screen, use the arrow keys to highlight Repair your computer, and then press Enter. (If Repair your computer isn’t listed as an option, then your computer doesn’t include preinstalled recovery options, or your network administrator has turned them off.)

Select a keyboard layout, and then click Next.

On the System Recovery Options menu, click a tool to open it.

To open the System Recovery Options menu using the Windows 7 installation disc or a USB flash drive, or a system repair disc

If your computer’s system is severely damaged and you can’t access the System Recovery Options menu on your computer, you can access it using the Windows 7 installation disc or a USB flash drive, or using a system repair disc if you created one earlier.

To use this method, you need to restart (boot) your computer using the disc or USB flash drive.

Insert the Windows 7 installation disc or USB flash drive, or a system repair disc, and then shut down your computer.

Restart your computer using the computer’s power button.

When prompted, press any key, and then follow the instructions that appear.

On the Install Windows page, or on the System Recovery Options page, choose your language and other preferences, and then click Next.

If neither the Install Windows page nor the System Recovery Options page appear, and you’re not asked to press any key, you might need to change some system settings.

If you’re using the Windows installation disc or USB flash drive, click Repair your computer.

Select the Windows installation you want to repair, and then click Next.

On the System Recovery Options menu, click a tool to open it.
