Windows 8 is Microsoft's latest operating system which is completely redesigned. It moves away from thetraditional interface to a completely new interface known as Metro User Interface. The familiar start menu is now gone. Icons and windows are replaced with live tiles and magazine styled interface. Unlike any previous versions, Windows 8 and its variation RT works across multiple architectures and has been optimizedfor touch screen. So it will work on Intel based PCs or an ARM based tablet.
This step-by-step guide demonstrates how to install Microsoft Windows 8 Professional. You can follow this guide if you have Windows 8 basic edition or any other version as the steps are very similar.
The best way to install Windows 8 is to do a clean install. Before you start the installation process I recommend that you check Windows 8 System Requirements to ensure that your hardware is supported by Windows 8. If you don't have Windows 8 drivers for all your hardware, it is a good idea to download all the drivers from the hardware manufacturers web site and save all the necessary drivers on a CD/DVD or a USB drive before you start the installation.
Windows 8 Professional DVD is bootable. In order to boot from the DVD you need to set the boot sequence. Look for the boot sequence under your BIOS setup and make sure that the first boot device is set to CD-ROM/DVD-ROM.
Step 1 - Place Windows 8 DVD in your dvd-rom drive and start your PC. Windows 8 willstart to boot up and you will get the following screen with a rotating progress bar.

Step 2 - The next screen allows you to setup your language, time and currency format, keyboard or input method. Choose your required settings and click next to continue.

Step 3 - The next screen allows you to install or repair Windows 8. Since we are doing a clean install we will click on "install now".

Step 4 - The setup process starts as shown.

Step 5 - At this stage you need to type your product key that came with your copy of Windows 8. Click next once you have entered the product key correctly.

Step 11 - You will notice that you have 3 partitions. Partition 1 is system reserved. Leave this partition alone. Partition 2 is 30GB primary partition that was created in the last step. The third partition is unallocated which means it is not being used. You can however format it and use it as a second storage drive. This can be done after windows installation is finished so I will leave it for now.
Choose partition 2 (Primary Partition). This is where I will install Windows 8. Click next to continue.

Step 12 - At this stage Windows starts to copy files to your hard drive and begins the installation. This process might take a few minutes depending on your computer specification. Now is a good time to grab yourself a coffee.

Step 29 - Finally the setup process is finished and you are presented with a completely new and unfamiliar Metro user interface. You have your most common application right in front of you. Clicking on any tiles will launch that application. At this point you can startusing your computer. However, it may not be fully configured. You need to make sure that all the hardware is detected correctly and the necessary device drivers are installed. This can be done from the device manager.

Step 30 - To go to device manager click search on charm bar on the right. Then type devmgmt.msc. Click on the devmgmt icon on the left.

Step 31 - You will see all your hardware listed as shown on the image below. You need to check if you have any yellow exclamation marks next to the name of the devices, similar to "Base System Device" on the image below. This indicates that the driver has not beeninstalled for this device.
At this stage you can install the driver for this device. To do so, Right Mouse click on Base System Device -> Update Driver Software...
Windows 7 pic6 - Click to enlarge
Step 32 - You can choose to "Search automatically for updated driver software" or "Browse my computer for driver software". If you have the driver CD or if the driver is on a USB drive then choose "browse my computer for driver software". Window 8 will search and install the driver from the CD or you can locate the driver manually.
Once you have removed all the yellow exclamation marks from the device manager your Windows 8 configuration would be fully complete.
