F8 will bring you to the Recovery Environment on some W7 builds. On others, the WinRE is not installed, apparently. With Vista, you can always automate the Recovery Environment with the winre.wim and boot.sdi files using the setautofailover.cmd command. It's best to locate them in a partition other than the OS partition and that may be what W7 does. Dell has used the automated Recovery Environment since Vista and uses it to contain a link to the factory image restore utility. Custom Recovery Environment options can be made by mounting the winre.wim using the Windows Automated Installation Kit, then adding the extras.
