text: can any plz tell me step by step to install o/s & what to do before ins. it.? it is about computer only.basically assembling. his is where we come in and try to lend a hand by providing to some of our novice users a few pointers about installing the microsoft windows xp operating system.  before beginning the installation please make sure you have collected all of the important disks received when the computer was purchased, which basically means driver disks for: motherboard, audio, video, network adapter (if you have one) and s-ata (if you have a s-ata hard disk). if you are installing windows xp without service pack 2, remove your network cable before commencing. also, if you are reinstalling windows, please make sure you have moved all important files from your desktop, my documents, program files and windows folders.  now you can start your computer and enter its bios (usually by pressing the delete button). search for the boot priority section (it should be in the first menu or in advanced bios featues) and make sure the first boot device is the cd-rom drive. now you can insert the windows xp installation cd in your optical drive and exit the bios (not without saving of course).  your computer will restart and after a few seconds will ask you to press a key so it can boot from the cd. press any key to start the windows xp installation process. after inspecting your computer, you will be asked to press the f6 key if you have a disk for your s-ata hard drive. it is very important not to skip or miss this step if you do have an s-ata hard drive!  if you have pressed the f6 key, you will be asked to specify your storage controller. hit the s key, insert the s-ata driver disk and press enter. after copying the needed drivers, you will see to the previous screen again. just press enter and let the setup process continue.  when the setup has finished loading files, you will have to choose between setting up windows, repair an existing windows installation and exiting the setup. you will of course press the enter key which brings you to the license agreement screen. you can agree by pressing f8 or disagree by pressing the escape key (this will stop the installation process).  the next screen is a partition manager; it will display available partitions and unused space on your hard drive. you can create a partition by pressing c, delete one by press d or use the arrow keys to select the partition on which windows xp will be installed. we do not advise you to delete partitions if you do not know exactly what this means. if the selected partition already has windows installed on it, you will have to choose between using the same partition for your installation and deleting the old windows (press l) or using another partition (press escape). if the hard drive doesn’t have any partitions (only unused space), you must create one: just press c and choose the partition size. after selecting a partition, the setup will ask you to format the selected partition. if you’ve just created the partition or if it doesn’t store any valuable information, you can use the quick ntfs format, but if the partition already existed and if you have important files stored on in it, you can choose to "leave the current file system intact (no changes)".  the setup will now start copying files and then reboot and install devices (please note that user intervention is not needed in any way, you might as well leave the computer alone until the setup finishes device installation). you have surely noticed that the device installation has began in a new, more user friendly interface and when it’s over a window will appear requesting you to modify your regional and language settings. to help certain services provide you with local information, you may choose your country in location menu. by pressing customize you can select number settings (decimal symbol, digit grouping, negative sign symbol, measurement system, etc), currency settings (currency symbol, decimal symbol, etc), time settings (time format, time separator) and date settings (short date format
