Planning the Installation
As with any OS installation, we must first plan the installation process. When you run the Windows 7 Setup program, you must provide information about how to install and configure the operating system. Thorough planning can make your installation of Windows 7 more efficient by helping you to avoid potential problems during installation. An understanding of the configuration options will also help to ensure that you have properly configured your system.
Here are some of the most important things you should take into consideration when planning for your Windows 7 installation:
- Check System Requirements
- Check Hardware and Software Compatibility
- Determine Disk Partitioning Options
- Complete a Pre-Installation Checklist
Microsoft states the minimum recommended specs for Windows 7:
- 1 GHz 32-bit or 64-bit processor
- 1 GB of system memory
- 16 GB of available disk space
- Support for DirectX 9 graphics with 128 MB memory (to enable the Aero theme)
- DVD-R/W Drive
- Internet access (to activate and get updates)
32-bit or 64-bit Version?
You need to decide whether to install the 32-bit or 64-bit version of Windows 7. The Windows 7 installation disc package includes both 32-bit and 64-bit versions of Windows 7. Basically, the 64-bit version of Windows handles large amounts of random access memory (RAM) more effectively than a 32-bit system. So if you plan on using Windows 7 on a computer with more than 3 GB or RAM, I would strongly suggest to use the 64-bit version. Most programs designed for the 32-bit version of Windows will work on the 64-bit version of Windows, and if they don’t, you can always use Windows XP Mode (read my “How to Install Windows XP Mode on Windows 7” article).
Note: Either way, you cannot use an existing 32-bit version of a previous OS to perform an in-place upgrade to a 64-bit version of Windows 7, and you’ll need to format and install a fresh copy. Also, you cannot use an existing 64-bit version of a previous OS to perform an in-place upgrade to a 32-bit version of Windows 7.
