Windows not starting from SATA hdd

Hello,
i have a IDE hdd with XP installed on it(C:WINDOWS)
added a second SATA hdd and installed XP on it to(D:WINDOWS)
When both hdds work no problem to start wich OS i want, but if IDE hdd is out NO BOOT RECORD message appears and can't start anything.(Even can't install fresh windows cos setup says no hdd found).
In BIOS everything is OK, SATA hdd is present at ch0!
What to do to make my system working again?
