I believe the F:Games drive which is also marked active is complicating Windows 7 normal ability to configure a boot menu.
Unplug all drives except your XP and Windows 7, boot into Windows 7 drive and run a Repair install which will reconfigure the boot correctly. A repair install in Windows 7 is an Upgrade install over itself, which leaves programs, files and settings in place but reinstalls the OS and freshly configures the boot.
If unplugging your data drives causes you to lose the ability to boot Windows 7, run startup repair from the Windows 7 installer repeatedly until it boots.
Please also post back here which drive is set to boot first in BIOS.
