Re: On start up screen goes to dos and says "you need to...
You have a mac with a program called boot camp. What you need to do is to hold the option key down once you restart it. Keep holding it down until you get to a screen that shows two hard drives on it, one says mac and the other says windows. Use the mouse or arrow keys to choose the mac icon and then hit enter. and yes, you will have to do this everytime you reboot.

There is no DOS mode on Apple operating systems. If you are concerned there is something wrong with the hardware or software of your Mac, insert the operating system install disc and restart the computer. After you hear the start up tone, press and hold the "C" key on your keyboard.
This will cause the computer to boot from the CD drive instead of the hard drive. In the menu bar, look for Disk Utility and try running some diagnostics.
The quickest way to get out of DOS is to hold down the power key until the computer shuts off. Then during restart, hold down the option key until the drives icons appear on screen. Use the arrow keys to select your OS for start up and away you go..
You should hold down the option key immediately after you hear the MAC strtup sound and don't let gotill you see your disk on the screen

Try reinstalling MacOS on your laptop, as far as I know, all Mac come with recovery disks. To boot of off a disk, make sure the disk is in the drive , reboot the computer, and press C while the chime is playing. You SHOULD be able to reinstall. What your describing usually happens to very old iMacs that have bad, incompatible, or no RAM installed. If none of the above works, take it to an Apple Store, they were very helpful when my iPod had a bad battery
