The Windows Boot Manager section describes the location of the boot manager, along with other identifiers. Hence, this was changed to a more secure but universal solution. However, a single insecure text file is vulnerable to attack. Previously, you managed your boot screen options using the tiny boot.ini file (and Windows NT boot loader, ntldr).
