If partitioning changes were made, verify that the correct partition is set active. If you later delete the XP partition or backup the Windows Vista/Windows 7 partition and restore it to another location (such as another drive) and then attempt to boot it, it will not boot since it does not contain the necessary boot files. For example, if Windows XP is already installed and you then install Windows Vista/Windows 7, the new installation will place its booting files on the XP partition. This partition may or may not be the selected Windows installation partition. Windows will install the booting files to the active partition on the booting drive.
This can be the result of the wrong partition being set active or that the booting files do not exist on the partition. These files include the bootmgr file and the \Boot folder (which contains the BCD file). The files necessary to boot Windows were not found on the partition booted. This may happen after making partition changes or after restoring the Windows partition. Instead, the following error message is displayed: When attempting to boot into a Windows Vista or Windows 7, Windows fails to load.
