bootloader problem

[MikhailZ]

Hi mac-masters! I need yo help! I need 10.5.7 (iAtkos for ex.) OS but also i tried Kalyway 10.5.2, iDeneb 10.5.5! All these releases installed succeded and i work in but for once! I could read internet, listening iTunes and all drivers worked perfectly, but when i want to restart my comp i lost it:((

 

Every OS i saw just once, because bootloader doesn't work! Everytime i see blinkin cursor and then DVD starts loading...again. Or if eject DVD then other HDD starts loading. I tried Chameleon v1 and v2, i tried many releases but there is one way:(((

 

I need your advice!!
