The F11 and F12 keys do not work when you try to install a 64-bit version of Windows 7 SP1 or of Windows Server 2008 R2 SP1 on an EFI-based computer

Symptoms

Consider the following scenario:

  • You try to install a 64-bit version of Windows 7 Service Pack 1 (SP1) or of Windows Server 2008 R2 Service Pack 1 (SP1) on an Extensible Firmware Interface (EFI)-based computer.

  • The F11 and F12 keys are assigned to an OEM-specific recovery sequence.

  • You press the F11 or F12 key during the installation process.



In this scenario, F11 and F12 keys do not work.

Notes

  • The F1 through F10 keys work correctly during the Windows installation process.

  • This issue does not occur if you install Windows in legacy mode.


Cause

This issue occurs because Windows 7 SP1 and Windows Server 2008 R2 SP1 do not support the EFI_SIMPLE_TEXT_IN_PROTOCOL_EX protocol.
