Consider the following scenario:
- You upgrade a Windows 7 PC to Windows 8.
- Intel Smart Response Technology (Intel SRT) is enabled to optimize performance through the use of a solid state drive (SSD) with a traditional hard disk drive.
- You boot into the Windows Recovery Environment (WinRE) and attempt to restore Windows 8 using the "Refresh your PC" or "Reset your PC" options.
The drive where Windows is installed is locked. Unlock the drive and try again.
