Hi, I am new, and I am also very distressed and confused!

I only intended to try and load Vista and OSX on my computer out of experimentation, and it is getting on my nerves. Please help!

What happened is I managed to install Vista quite easily apart from XP, and after that I followed the fool-proof guide and installed the iatkos leopard. It seemed to install fine, I followed all the instructions but there's something weird going on, OSX doesn't seem to want to boot.

The first thing that was weird for me is that the Vista Boot loader screen still came up after I installed Leopard, it looked like this: http://apcmag.com/system/files/images/xp_vista_10.jpg

I thought maybe I could just use the EasyBCD tool to add the OSX boot option in, but then when I start up and try to select the OSX option, it does not work and says "windows failed to start" lots of stuff, then

"File: \NST\nst_mac.mbr"
"Info: The selected entry cannot be loaded because the application is missing or corrupt"

I tried setting the Vista drive to be active then when I restarted it wouldn't let me boot and "NTLDR cannot be found. Press Ctr-Alt-Del to restart" I could only get past that by using Parted Magic to switch the boot flag around.

I have no idea what I should do now, should I give up, or am I closer than I think? PLease help me!
