How-to: Windows Recovery Environment (WinRE), Safe mode and Win PE.
A successor to the Windows Recovery Console, Windows Recovery Environment (WinRE) is a set of tools based on Windows Preinstallation Environment (Win PE). Windows PE utility (Wpeutil) is a command-line tool that enables you to run commands during a Windows PE session
Boot to Safe Mode
When dealing with a Blue Screen of Death or other critical errors – one option
is to boot into Safe Mode.
- On the Windows sign-in screen, press and hold SHIFT while you select Power > Restart.
- After the PC restarts to the Choose an option screen, Troubleshoot > Advanced options > Startup Settings > Restart.
You may be asked to enter your BitLocker recovery key.- After your PC restarts, you’ll see a list of options. Select 4 or F4 to start your PC in safe mode. Or if you’ll need to use the Internet, select 5 or F5 for Safe Mode with Networking.
From safe mode you can run a system restore with %systemroot%\system32\restore\rstrui.exe
Boot to 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 and have access to Bootrec.
Boot to Windows PE
WinPE most often runs from an external USB device like a memory stick. This can be used to disable services or replace system
files until you are able to boot into safe mode.
- Connect the device.
- Turn on the PC, and use the boot menus to select the Windows PE drive. Typically this requires pressing a hardware button or a key, such as the Esc key. For UEFI-based PCs, you might need to find an option to manually select the UEFI boot files, for example, USBDrive01\EFI\BOOT\BOOTX64.EFI.
- Windows PE starts automatically. After the command window appears, the wpeinit command runs automatically. This might take a few minutes.
WinPE drive letter assignments change each time you boot
