My old motherboard finally gave out and i replaced it with a different motherboard and CPU but i am using the same HDD. It has windows XP home edition on it. when i try to turn on my computer it takes me to boot in safe mode or normal mode, and keeps booting to this screen. well i have a copy of windows XP Pro i tried to install. i set my bios to boot from CD-ROM first and i keep getting NTLDR not found press ctrl+alt+del. is this because i have windows xp home edition on this?
