You can choose one of the following options:
• If your computer already has some version of Windows installed and you want to replace it with Windows 7 without making any changes to your partitions, boot into it, insert the Windows 7 installation disc into the DVD drive or mount its image using PowerISO or Daemon tools and the likes. Then open the Autorun File or Setup.exe.
• If your computer doesn't have an operating system installed or if you want to create, extend, delete, or format partitions, you need to restart your computer with the installation disc inserted in your DVD drive. This causes your computer to start (or "boot") from the installation DVD. If you are asked to press a key to boot from DVD or CD, press any key. For this to appear, ensure that your DVD drive is set as your first boot device in BIOS. Some manufacturers even give the option of selecting the boot device from a menu without entering BIOS by pressing some function key. Check the first screen that appears when you start your comp for that.
• You will see the Install Windows page. Click on Install now.
• On the "Get important updates for installation page", we recommend getting the latest updates for better driver compatibility and latest security patches. You will need an Internet connection for this. If you use a proxy for connecting to the net, enter it in your IE settings.
• Next, check the “I accept the license terms” option on the Please read the license terms page.
• Click on Custom when you get to the ‘Which type of installation do you want?’ page
• Next you will get the “Where do you want to install Windows?” page. Do one of the following:
• If you don't want to specify a specific partition to install Windows on, or create partitions on your hard disk, click on Next to begin the installation.
• If you already have another existing partition with enough free space and want to have more than one operating system on the same computer, you can install Windows on that partition. This is called a dual-boot or multiboot configuration depending on the number of Operating systems installed. Make sure to install Windows on a different partition from the partition where your other versions of Windows are installed. Select the partition you want to use, and then click on Next to begin the installation.
• If you want to create, extend, delete, or format a partition, click Drive options (advanced), click the option you want, and then follow the instructions. Click on Next to begin the installation. The Drive options (advanced) option is disabled if you have started the installation from your previous Windows and not booted from the installation disc.
• Now just follow the instructions and you should be set with a new Windows 7 in no time.
