This is the Windows 10 way (I shit you not):
Before you enter safe mode, you need to enter the Windows Recovery Environment (winRE). To do this, you will repeatedly turn your device off, then on:
- Hold down the power button for 10 seconds to turn off your device.
- Press the power button again to turn on your device.
- On the first sign that Windows has started (for example, some devices show the manufacturer’s logo when restarting) hold down the power button for 10 seconds to turn off your device.
- Press the power button again to turn on your device.
- When Windows restarts, hold down the power button for 10 seconds to turn off your device.
- Press the power button again to turn on your device.
- Allow your device to fully restart. You will enter winRE.
Also for some fucking reason safe mode defaults to having a fucking floating bing bar in the middle of the screen? Like, why? Stop hurting me.
