How to reinstall windows xp from cd for gigabyte (Model: GA K8VM800M)

This error seems to be related to Windows thinking that your hard drive needs a special SATA driver. Notice when Windows begins to install or re-install, there's a time at the beginning when it lets you press F6 to load special drivers, such as RAID. This would be when you'd insert a floppy disk with that driver.

Now, you may not really need this driver. In your BIOS, there are settings related to the way the OS will communicate with the drive.

Here's the spec page for your motherboard - I used Rev2, there is also a Rev1

There are two manuals related to your motheboard. One is the normal manual:

The other is the SATA/RAID/OS manual related to setting up special features to have your drive communicate with your OS (Windows).

Let's assume that your drive is NOT required to run the special driver, but the BIOS is telling it to do so. You need to check the settings in the BIOS under Integrate Peripherals / SATA Mode. There are at least two settings here. One is RAID, the other is IDE and there may be another choice called AHCI. The manual doesn't mention AHCI but it is a type of SATA driver that enables more advanced features. It's possible that your drive is set up in this way and the BIOS is set up to not look for it. Or could be set up for RAID or such. Look at the choices listed and let us know if AHCI is there.

What is the format and feature of your drive? If it's RAID, you need to specify RAID in the BIOS and follow the instructions in the special manual for enabling it, making the driver disk, etc... If it's not RAID, you need to make sure the BIOS isn't telling it that it is.

Read thru both the main manual and the RAID/OS manual for info. Look at your BIOS settings. Let us know in follow-up what you find and know about these features.
