Advanced startup enables you to perform these actions:
- Start recovery (aka: Windows RE or WinRE), troubleshooting, and diagnostic tools.
- Boot from a disk (ex: USB or DVD) or device (UEFI only)
- Access the PC’s UEFI firmware
- Restore Windows from a system image
- Choose default operating system to boot to on PC if multiple operating systems are installed
When you boot to advanced startup, all user sessions are signed off. If you select a Windows RE feature from this menu, the PC restarts into Windows RE and the selected feature is launched.
- In some situations, Windows RE automatically tries to repair the system. Also, these situations automatically cause a failover to Windows RE:
- Two consecutive failed attempts to start Windows.
- Two consecutive unexpected shutdowns that occur within two minutes of boot completion.
- A Secure Boot error (except for issues related to Bootmgr.efi).
- A BitLocker error on touch-only devices.
This tutorial will show you how to add or remove Boot to Advanced Startup Options to the Desktop context menu for all users in Windows 10.
