Im trying to install windows xp in Zenith computer.but the message is "windows did not find any hard disk" please help me!

Hi, According to the description, it seems that you have configured the SATA hard drive to AHCI mode in BIOS. The original Windows XP installation disk doesn't have any drivers for SATA drive, so you have to change the SATA hard drive from AHCI mode to IDE/Compatibility mode in BIOS, or you can integrated SATA drivers to the installation disk yourself. For more information, you can refer to: How to Get AHCI Working Properly in Server 2008 with Hyper-V http://social.technet.microsoft.com/Forums/en-US/winservergen/thread/7e58be1f-3e97-44cf-ae11-de2627d9cd94 Best Regards, Vincent Hu
