Your going to take your disk (if muiltiple disks, then take the first disk or any disk that says something like "install" on it or something) and simply insert it into your CD-ROM drive. A screen is going to pop up. It should be a GTA San Andreas screen. There should be a button that says "install". Click that and simply go through the process. If there is any option, once you press the "install" button, to do a default or standard install or a custom install, just choose default or standard. The game should start to install. If there are multiple disks then in the middle of the install its going to ask for the other disk(s). What you do is when the window pops up asking for another disk, just eject the disk that is already in your computer and insert the other one. Once the other disk is in, close the CD-ROM drive and it should continue the install.
