Withe the help of an installation disc, all of these would be completed very easily, which is essential. The disc has to go into the CD/DVD-Rom, after which navigate to BIOS by pressing F2, F10 or F11, as per the system you are installing in. Under Boot wise use the arrow keys or +/- to place the CD/DVD-Rom as first option & reboot the system. The installation will start automatically and then you need to follow the on-screen instructions. During the setup, you need to punch in the activation key, which activates the OS. Once the installation is finished in about 1 - 1.30 hours, then you are ready to go. Do eject the disc once the installation is complete.
Note:
During the installation process, the system reboots for a number of times, since the installing of important & many of the programs require system restart, so do not panic.
