Uninstalled windows from mac, but MAC OS still won't load without pressing option key?

Question

The mac operating system wont load unless i hold down the option key while the computer is starting up. otherwise it says 'no bootable disk-load device' or something of that nature

Answer 1

you probably have "boot camp" installed on your mac, because thats what you need for vista to run on a mac, but you should probably take it to a computer doctor.

a lot of people aren't really experienced in this kind of thing so you should fix it with proffesionals.

Answer 2

Once you're booted into OSX, open your system preferences.  Click on STARTUP DISC.  Select the disc you want to start from.  Click on restart.  Your Mac will now start from that OS.
