How To Restart In Safe Mode | Fix Stubborn Startup Bugs

If your computer or phone is acting weird, Safe Mode is the cleanest place to troubleshoot. It loads the bare minimum, so you can spot what’s breaking things without a pile of extra apps and startup items getting in the way.

This walkthrough shows how to restart in Safe Mode on Windows, Mac, Android, and what to do on iPhone when people say “Safe Mode” (since iOS works differently). You’ll get clear steps, a fast checklist for what to try once you’re in, and an exit plan so you don’t get stuck.

What Safe Mode Does And When It’s Worth Using

Safe Mode is a stripped-down startup. It loads core system pieces and skips most extras: third-party drivers, auto-start apps, and many background services. That makes it useful when normal startup keeps crashing, freezing, or throwing errors.

Safe Mode is worth using when you see patterns like these:

• Your PC boots to a black screen, then reboots.
• A driver update made your display, Wi-Fi, or audio act up.
• A new app causes constant crashes or CPU spikes.
• Your Mac won’t behave after a login item, extension, or update.
• Your Android phone keeps restarting or a downloaded app breaks core functions.

If the problem vanishes in Safe Mode, that’s your clue. Something that normally loads at startup is likely the culprit.

Before You Restart Take Two Minutes To Prep

These quick moves save time once you’re inside Safe Mode:

• Save open work and close apps. A restart is coming.
• If you suspect a driver issue, note what changed last: update, install, new device.
• If your disk is encrypted, locate your recovery key if your device asks for it.
• On Android, note any recent installs. Safe Mode often points right at a downloaded app.

Safe Mode can look a bit different than normal startup. That’s normal. The goal is a stable session where you can undo what went wrong.

How To Restart In Safe Mode On Windows, Mac, Android, And iPhone

Pick your device below and follow the steps as written. If your device is stuck in a boot loop, use the “Can’t sign in” paths for Windows or the shutdown paths for Mac.

Windows 11 And Windows 10 From Settings

This route works when you can still get into Windows.

1. Open Settings.
2. Go to System > Recovery.
3. Under Advanced startup, select Restart now.
4. On the blue menu, choose Troubleshoot > Advanced options > Startup Settings.
5. Select Restart.
6. When the list appears, press 4 for Safe Mode, 5 for Safe Mode with networking, or 6 for Safe Mode with Command Prompt.

If you’re unsure which one to use, start with plain Safe Mode. Use networking only when you truly need internet access.

Windows From The Sign-In Screen

This route works when Windows reaches the sign-in screen but crashes after login.

1. At the sign-in screen, select the Power icon.
2. Hold Shift, then click Restart.
3. Go to Troubleshoot > Advanced options > Startup Settings > Restart.
4. Press 4, 5, or 6 when prompted.

This is one of the quickest ways to reach Safe Mode without digging through Settings.

Windows When You Can’t Sign In At All

If Windows won’t reach the sign-in screen, you can still trigger the recovery menu.

1. Turn the PC on.
2. When you see Windows start to load, hold the power button to force it off.
3. Repeat that power-on, force-off cycle three times.
4. On the next boot, Windows should show recovery options.
5. Select See advanced repair options, then follow Troubleshoot > Advanced options > Startup Settings.

If you reach Startup Settings, choose Safe Mode using 4, 5, or 6. Microsoft’s Windows startup settings page outlines this recovery flow and the Startup Settings menu path. Windows startup settings

Mac With Apple Silicon

Safe Mode on newer Macs starts after a full shutdown.

1. Shut down your Mac.
2. Press and hold the power button until you see Loading startup options.
3. Select your startup disk.
4. Hold Shift, then click Continue in Safe Mode.
5. Log in when prompted. You may need to log in twice.

Apple’s Mac help page shows the Apple silicon steps and how Safe Mode behaves during startup. Start up your Mac in safe mode

Mac With Intel Processor

On Intel Macs, the Shift key timing matters.

1. Shut down your Mac.
2. Press the power button, then press and hold Shift right away.
3. Release Shift when you see the login window.
4. Log in. You may need to log in twice.

Once you’re in, test the issue. If the Mac runs fine in Safe Mode, look at login items, extensions, or recent installs once you’re back in normal startup.

Android Safe Mode On Pixel And Many Other Phones

Android Safe Mode blocks downloaded apps from running. That makes it great for spotting a problem app.

1. Press and hold the power button until the power menu shows.
2. Press and hold Power off.
3. Tap OK or Restart in Safe Mode when the prompt appears.
4. When the phone restarts, look for Safe mode on the screen.

If your phone is stuck and you need a hardware-button method, many devices enter Safe Mode by holding Volume down during boot until the lock screen appears.

iPhone And “Safe Mode” What People Usually Mean

Stock iOS doesn’t have a Safe Mode toggle like Windows or Android. When someone says “iPhone Safe Mode,” they usually mean one of these:

• Force restart to clear a frozen state.
• Recovery mode or restore steps when iOS won’t boot cleanly.
• Jailbreak Safe Mode, which exists only on modified devices.

If your iPhone is frozen, a force restart is the nearest “clean restart” you can do without changing settings. On Face ID iPhones: press Volume up, press Volume down, then hold the side button until the Apple logo appears.

How To Tell You’re In Safe Mode

You don’t want to guess. Here’s what you’ll usually see:

• Windows: “Safe Mode” text in the screen corners, lower resolution, fewer startup apps.
• Mac: slower login, some features limited, then normal desktop with fewer background items.
• Android: “Safe mode” label on screen; third-party apps are greyed out or missing from the launcher.

If the device still crashes inside Safe Mode, the issue may be deeper: corrupted system files, disk problems, or a failing component.

Safe Mode Entry Methods At A Glance

Device	Fastest Safe Mode Path	Notes
Windows 11 (can log in)	Settings > System > Recovery > Advanced startup	Pick 4, 5, or 6 on Startup Settings
Windows 11 (sign-in screen)	Shift + Restart	Works even if login crashes
Windows (won’t boot)	Three forced shutdowns to recovery	Leads to Troubleshoot menus
Mac (Apple silicon)	Hold power > Startup options > Shift	“Continue in Safe Mode” appears
Mac (Intel)	Hold Shift during power-on	Release at login window
Android (most models)	Long-press Power off	Blocks downloaded apps
Android (hardware method)	Hold Volume down during boot	Useful if screen taps fail
iPhone	Force restart	iOS has no stock Safe Mode switch

What To Do Once You’re In Safe Mode

Safe Mode is a workbench. Do the smallest change that proves or fixes the cause, then restart normally to verify. Start with what changed most recently.

Uninstall The Last App Or Driver You Added

If trouble began right after an install, remove that item first.

• Windows: uninstall the last app, driver, or update. If a driver caused it, roll it back in Device Manager.
• Android: remove the newest downloaded apps, one at a time, then reboot normally to test.
• Mac: remove recent login items or extensions tied to the issue.

Disable Startup Apps And Login Items

Startup clutter can trigger crashes or slow boots. Safe Mode proves what happens when those items don’t run.

• Windows: open Task Manager > Startup apps, disable items you don’t trust.
• Mac: check Login Items in System Settings, remove what you don’t recognize.

After disabling, restart normally and see if the issue stays gone.

Scan For Malware If The Symptoms Match

If you saw pop-ups, browser redirects, new toolbars, or sudden CPU spikes, run a malware scan. Safe Mode can help a scan run without interference from unwanted startup items.

Use a well-known security tool you already trust. If networking isn’t needed, stay in plain Safe Mode to reduce risk while cleaning.

Check Storage And Free Space

Low storage can cause unstable updates, app crashes, and failed boots. In Safe Mode, delete large files you don’t need, clear temporary data, or move files to external storage.

On Windows, a quick disk cleanup plus removing old installers can free space fast. On Android, clear storage-heavy apps and remove unused media.

Repair System Files On Windows

If Windows keeps breaking even after removing obvious culprits, run built-in checks. In Safe Mode with Command Prompt, you can run system file checks and disk checks. Stick to standard tools built into Windows so you’re not adding new variables during troubleshooting.

Fix Paths For Common Safe Mode Scenarios

Problem You See	What To Try In Safe Mode	Restart Test
PC crashes right after login	Disable startup apps; uninstall last app	Restart normal and log in
Bad display after driver update	Roll back display driver; uninstall driver	Restart normal and check resolution
Wi-Fi missing	Use Safe Mode with networking; reinstall Wi-Fi driver	Restart normal and connect
Mac freezes after login	Remove login items; check recent extensions	Restart normal and log in
Android keeps restarting	Remove newest downloaded apps	Restart normal and watch stability
Android battery drain spike	Check which app stops draining in Safe Mode	Restart normal after uninstall
Windows stuck in boot loop	Reach recovery; use Startup Settings	Restart normal after changes
Mac fan runs loud at idle	Test Safe Mode; remove heavy background items	Restart normal and watch temps

How To Exit Safe Mode Cleanly

Leaving Safe Mode should be simple. In most cases, a plain restart is enough.

Exit Safe Mode On Windows

1. Restart the PC from the Start menu.
2. If you used a boot setting tool like System Configuration earlier, open it and clear the Safe boot option before restarting again.

If Windows keeps returning to Safe Mode, a Safe boot setting may still be enabled, or Windows may be routing you back into recovery due to a boot failure.

Exit Safe Mode On Mac

1. Restart your Mac normally.
2. Don’t hold any keys during boot.

If your Mac returns to Safe Mode each time, check for stuck keys on the keyboard, then review login items and startup disks.

Exit Safe Mode On Android

1. Restart your phone.
2. If Safe Mode persists, power off fully, wait a few seconds, then power on.

If Safe Mode won’t clear, a volume button may be stuck. Remove the case and check the button feel, then reboot.

When Safe Mode Doesn’t Fix It

Safe Mode is great at isolating software conflicts. If the device still fails inside Safe Mode, think in these directions:

• Storage issues: failing drive, file system corruption, repeated read errors.
• System damage: broken system files, incomplete updates.
• Hardware faults: RAM errors, overheating, failing battery.

At that point, back up what you can, then move to deeper repair steps like recovery tools, reinstalling the OS, or hardware diagnostics. Safe Mode already gave you a clean test: if it still breaks there, the fix is rarely “one setting.”

A Simple Safe Mode Workflow That Saves Time

If you want a repeatable pattern, use this every time:

1. Enter Safe Mode using the fastest method for your device.
2. Confirm the issue: does it still happen in Safe Mode?
3. Undo the most recent change first: app, driver, update, extension, login item.
4. Restart normally and test right away.
5. If it’s fixed, stop. Don’t pile on extra changes.

That’s the sweet spot: one clean test, one clean change, one restart to verify.
