Snow leopard install wiped out system

Hi vee4kids & welcome to discussions...

Which version OS was installed before? Do you still have that DVD?

Could you be a bit more specific about what said what? There is no 'can't change disc' error message in the installer, so a more nearly accurate post of the message would help.

I tried to Do disc repair and it could not be done now it wont start up on anything.

Again, could you be more specific here? Why can't you do Disk Utility's "Repair Disk" step? Did you restart from the installer disk to do this, as Disk Utility tells you you must do if that option is greyed out?

Is this the essence of the message your revieved: 'Snow Leopard cannot be installed on Macintosh HD the disk cannot be used to start up your computer."
