unlocked

finally made myself a shiny Nlited XP SP3 + intel(R) ICH9M E/M SATA Controller.
Q&A:
Q: is it working?
A: Yes
Q: so you've successfully installed XP on partition?
A: Yes
Q: so,you have dualboot computer now?
A: nope, i don't even have any boot

the XP installation ran smoothly.
i notice something strange though (not sure if it's related).
when i insert my name & company name, the
M key actually type a
4. some letter keys typed different numbers

anywho,... the installation finished, the machine reboot, i got the XP symbol about 1 second, and then BSOD for about half a second, and then i got the
safe mode, last known configuration,start windows normally screen.
i tried each one of them, got the same result, BSOD for half second (can't read the error code) & get back to the safe mode,last known config screen. i have to shutdown the computer from BIOS.
well, i know from the tutorial that once you've installed XP, the vista bootloader won't work, and then i suppose to use
vistabootpro from XP to fix vista bootloader.
but now i can't even use XP

i think there's a way to fix vista bootloader by dowloading vista recovery disk .ISO & burn it on CD
or using separate vista OS installer. but i can't make recovery disk since the only CD writer i have is on the laptop & i don't have vista OS installer 
so...here i am, point of no return, guess i have to stick with 1 OS after all huh? 
it's 11PM here. i'll just leave the brick lappy today.
tomorrow i'll try installing XP & hunt for VAIO drives.
nah, i'm back to Vista 64

used vaio recovery disk, i managed to boot into vista.
back to square one
