Tell us what is on each partition. Dual Boot Installation with Windows 7 and XP
There is no reason to install Windows 7 to any drive letter except C. Even if another OS is already on C, Windows 7 will assume another letter when not booted and assume C when it is booted. This works fine and causes no problems whatsoever. So be sure to boot the installer when you install Windows 7 so it always assumes C when booted. Clean Install Windows 7
