I sucessfully install ipc 10.5.6 and then vista using easybcd

by accident I update my osx with auto update

Now it cannot boot... by itself it keep going to apple screen then keep reboot

I did try using ipc 10.5.6 dvd but could not get pass the apple logo, it keep rebooting also


However I can boot to vista
I don't know what happend, now I mess up with easybcd delete mac boot and add back

Now it getting worse, it seem that my mac loader is gone

still I could not boot from ipc 10,5.6 dvd





Please let me know if someone know what happend

More information,



When I reboot, before anythings I always get strange noise very high frequency beep when I push the power button to restart. It seem that there are something wrong there.


I have been successful to boot in OSX again last night by change again the bios to disable the ACHI then run xpress rovery2 from Gigabyte, then put it back to ACHI and run Ipc installer but did nothing just use the disk utility to check my partition.


Then with no strange noice, I can boot again.... to sad now in the morning everything go back and I could not boot into osx again


anyone know anything?
