How to Remove Windows 7 Boot Manager

The Windows boot manager, also known as the boot loader, it tells your computer how and which operating systems to load. In some cases, the boot manager may list a Windows 7 option if you've ever installed or configured a trial, beta or secondary version of Windows 7 on your default XP, Windows 7 or Vista computer. In others, a technical glitch could cause the boot manager's selection menu to load even though you may have already un-installed the secondary operating system. In either case, you can remove the secondary Windows 7 boot option and/or selection menu whether you're running a default Windows XP, Vista or 7 systems.
