The problem is that your System Active partition has been derailed into F: Downloads partition, there is no System Reserved boot partition to recover it into, and Windows 7 is presently a Logical partition which cannot be marked Active to recover System MBR. . Use free Partition Wizard bootable CD
to convert Windows 7 partition from Logical to Primary, mark it active, mark F: inactive, then use Windows 7 DVD to recover MBR into Windows 7.
Boot PW, allow files to load, select 1 for screen res, right click on Windows 7 partition>Modify>Set Partition to Primary, OK. Then rightclick Windows 7 again>Modify>Set to Active, OK.
Now rightclick F: Downloads partition>Modify>Set to Inactive, OK. Apply all steps.
Windows 7 will not now boot. Instead boot Windows 7 DVD, select Repair on second screen, click through to Recovery tools list to run Startup Repair up to 3 separate times as it will attempt to repair and finally write System MBR to Windows 7 partition.
Finally, from Windows 7 use EasyBCD 2.0 beta to Add XP as given earlier.
