How to Install Windows on a new computer

If installing in computers with SATA drives, have to check for RAID in BIOS so the installation can have no problems. Access BIOS pressing [del] at startup. In BIOS menu select "Integrated Peripherals" and then set "SATA RAID/AHCI Mode" to "Disabled" if it is currently set to "RAID". If the settings were already set to "Disabled" (default) do not do anything.
If having several HD choose one between 100-200GB as the primary HD defining it in BIOS (HOW?). This drive will be the one to install the operating system, later on.
Exit BIOS saving settings if done nay changes.
Insert Windows CD in drive.
Boot the computer (if coming from step 1 computer is automatically booted) assuring that will boot from cd (try first, if not booting from cd, check info on startup screen to know shortcut keys to boot menu ([del] for BIOS or could have an independent menu (e.g. [F12] but it may change according to machines)).
