The UEFI requirement means that the advanced startup menu is always accessible from within Windows.“BOOTMGR is compressed” is a common system error when starting your Windows 10/8/7 PC to the desktop.
Windows 11, unlike Windows 10, does not support systems that are running a BIOS - they must be using UEFI. System images are much larger and more complete than restore points and include all of your files, programs, and settings.
System Image Recovery: System Image Recovery is similar to System Restore, but uses a complete system image instead of a restore point. System Restore: System Restore allows you to use a previously created restore point to roll back Windows to a point where it was working correctly. UEFI Firmware Settings: This option restarts your computer and opens the BIOS/UEFI. Uninstall Updates: The Uninstall Updates option will roll back the latest updates installed, including major Windows versions or updates. Command Prompt: The Command Prompt option brings up a Command Prompt window that can be used to run diagnostic or repair commands. You can do things like enable Safe Mode, debugging, or boot logging, to name a few. Startup Settings: Startup Settings allows you to change how Windows 11 Boots. Startup Repair: Startup Repair will attempt to automatically fix issues that prevent Windows 11 from booting correctly.
