Booting into Safe Mode in Windows 11 can be crucial for troubleshooting issues. To enter Safe Mode, restart your computer and press the F8 key repeatedly as it boots up. This should bring up the Advanced Boot Options menu. If F8 doesn't work due to fast boot times, you can also access Safe Mode through the system settings. Navigate to Settings > Update & Security > Recovery, under Advanced startup, click 'Restart now'. Once your computer reboots to the Choose an Option screen, go to Troubleshoot > Advanced options > Startup Settings, and then click 'Restart'. After your PC restarts, you'll see a list of options; select 4 or F4 to start your PC in Safe Mode.
