Selecting the Windows 7 boot menu item and then pressing F8 gives one access to the "Advanced Options" boot menu as is the case in most recent Windows operating systems. Windows 7 however includes as the default entry the Windows Recovery Environment or WinRE.
"Repair Your Computer" which in Windows Vista was only available by booting to the Vista installation DVD, is now accessible from the boot menu in any configuration of single, dual or multi booting the OS. See Windows 7 Built-in Recovery Partition and Options
for more screenshots on the available recovery tools and options.
"The great majority of mankind are satisfied with appearances, as though they were realities, and are often more influenced by the things that seem than by those that are." - Niccolo Machiavelli
