You cannot 'remove' the Mac OS. The computer will not function without it. Macintosh computers need, and can only function with, the Mac OS. What you can do, possibly, is revert to an earlier version of the OS, if you still the disks the computer came with, or you can possibly upgrade to newer OS than the one you are currently using. If you want to revert, then insert the installation disk and set it as the start-up disk and then follow the onscreen instructions. This will delete the existing OS and install the desired one. If you are upgrading, insert the installation disk and set it as the start-up disk. Then follow the instructions. This will upgrade the existing OS to the newer one.
If you apply power, yes. But it will be able to do considerably more with an OS.
Installing Operating System (OS) needs registration to function fully. Maybe, you install unregistered OS that's why it comply the needs of CD. I suggest you reformat it. Buy the retail OS (if can't afford crack your OS out) so it won't ask you again about the OS error.
