My Mac thinks it's a Windows machine

[Seanog]

Was using Windows partition on Boot camp and now cannot get out of it. Mac starts in Windows every time. Keyboard seems unresponsive until system is loaded. Tried changing HD but comes up "no boot disk - insert boot disk".
I know the HD has a Mac Os. Was last using X.6.8

did you install the Startup Disk app and the other Windows drivers?

 

[Seanog]

Yes, was working fine for a long time. Can't think what happened.
I got the Snow Leopard out by connecting the mouse directly to computer and not the keyboard.
Inserted a Windows Dvd and it wants to install Windows but fails. If I eject the Windows Dvd I get "No OS found"
Got hold of a Windows keyboard which works. Tried ALT by startup as it's supposed to be equivalent of Option key but no luck.
