So I start up my iMac (late '07 alu) and I get greeted by a stop symbol and automatically get logged onto windows vista😕 Any ideas of what's going on?

Thanks
 
Have you tried pressing option on boot to get to the selector screen?

If you just want to restore it so it defaults boots into OS X press cmd+option+p+r on boot this will clear your PRAM (when the default boot option is stored).

Or if you are in windows then you can get the boot camp system tray item up and select to boot into OS X this will hopefully kick it into going to OS X.
 
you must hold the option key before the apple chimes. if you hold it any later it will not give you the hard drive options.

when you get to the mac side, you need to go to your settings and go to start up disk and choose mackintosh.
now that i think about it, this may not be your problem, but just throwing it out there.
 
If you are in Vista, there is a BootCamp icon on the right side of the taskbar.
It gives you the option to choose the startup disk too.
