Windows is generally the Operating System of choice - and the only O/S I will be covering.
Remember on systems using a hard drive with a previous O/S installed to it a reformat will be required, if you try to add your hard drive in this state the PC will lock on boot-up or after post. (usually the PC will just hang) This section of the guide is very brief, the reason for this is because each O/S has specific ways of installation and since I am limited by space and time I will only cover the necessities to get you to the point of being ABLE to install the O/S correctly. Generally, the O/S installation, after the format/partitioning procedure is automatic- you just need to answer a few basic questions for the O/S to complete it's installation. You will have the ability to add/remove specific programs after the O/S is installed.
Where shall we begin? Ah, formatting! To begin with you will have to format or reformat depending on your hard drive's condition. Now depending on your Windows experience this will either be an easy task or one of learning. Set aside a few hours for this procedure. Shall we begin?
After you have your system assembled and the Bios set to your preferences, you can proceed to the installation of Windows. To do this a Windows operating system will be required. Asus only supports Windows versions of 98SE and up other operating systems will require support from their manufactures. Formatting- this can be done in one of two ways; either using the CD or a floppy disc, for the O/S install you will need the Windows CD. The CD method is far superior to the floppy method and much faster. So we will use the CD method.
Place your Windows CD into the CD-ROM drive and then enter the Bios and set the drive order to boot from to the CD-Rom you will be using (the one your Windows CD is located in). That is to say- from the system Bios you have to change the drive boot sequence order, you may do this from the Advanced section of the system Bios. Set the CD-ROM of choice to the first boot position. After this, re-boot your PC. Now the system will read from the CD you have installed first, rather than your hard drive(s). After the O/S install you will need to change this setting back to the normal setting. The CD drive upon re-boot will spin up and the data will be read from the CD. Then after a few seconds a screen should be prompted and all you have to do is follow the on-screen instructions. It's that simple- really, well sort of.
Remember- we need to format our new drive, after Windows does a quick scan (this can take a few minutes) of your system a new screen will pop-up stating Windows has found the following drive(s) would you like to partition this drive? You will see lower in the screen your drive(s) listed and the size available for a partition; you may only partition one drive at a time. Highlight your selected drive and press enter. Based on your type of operating system- Windows 98SE will now ask you if you wish to use large disc access- select yes to this. Windows 2000 or XP will ask if you wish to use the NTFS file system Select yes to this. Press enter for any of the Operating Systems mentioned and then follow the on-screen instructions. Windows will now format your hard drive for you and prepare it for the Windows O/S. At this time the procedure is self initiating, and will take quite some time depending on your hard drive size, the larger the drive the longer the process. When this process is finished Windows will be ready for installation. Because of the wide variety of Windows applications, user preference and the like, it is not with in the scope of this guide to instruct you further about your Windows installation because from here it is more or less- defined by your choices. However, our main objective was achieved and you now are ready to install Windows to your hard drive.
