The reason that we dont have software for XP is that XP does not use the BCD to boot. It uses older technology called the boot.ini file. The BCD was introduced with Windows Vista and has been used since. The only way to fix a XP Boot issue is with the XP CD, which cant be hosted or downloaded legally.
So while you can use EasyBCD to add boot entries for XP, XP is not controlled by the BCD to boot.
