I am using HP Compaq 6720s Notebook PC Laptop.

I installed Windows Vista trial two months ago.

Now i wish to install Windows XP on it.

When i boot the Laptop from Win XP CD, setup run, and finally shows the error "there is no hard disc found."

Now how can i install Win XP?

My Laptop is brand new and every hardware is 100% working.

If i try to reinstall Win Vista, it will installed, but error shows only in Win XP CD.

I also changed the CD, but the problem was same.

Do you know who the Hard Drive manufaacturer is?

You can down load tools from the manufactuer's website,

As an example;

Go to seagates site and look for SeaTools for DOS. You have to register at this site.

Regisiter, then download the ISO. I use ImgBurn to write image file to disk.
Then you can boot your laptop from the disk and run diagnostics on your Hard Drive.

If you are able to load Windows Vista on the computer and it can "see" your hard drive, but when you try to install Windows XP, it cannot "see" your hard drive, you are having a driver issue.

The driver in question is for your SATA controller.

You will need a copy of Windows XP that is Service Pack 2 or you will have to integrate Service Pack 2 into your existing copy of Windows XP.

Hope this helps,

Actually I want to install Windows XP over Windows Vista, and his "downgrading" was not possible.

I put a question on this forum, and searched this problem on internet.

There are two solutions.

1: Go into BIOS and disable the Sata Mode. and then try to boot from Windows XP cd.

2: Download a freeware software DBAN, make a bootable cd, and boot ur laptop from cd. This software will wipe all ur data. The try to install Windows Xp.

Most likely, you have SATA hard drive and Windows XP CD doesn't provide SATA drivers. You have to install then separately.

What OS came on your computer originally? If it was XP there maybe the recovery partition on your hard drive. I would try accessing it before doing anything else. If you cannot do that, then visit http://www.hp.com and purchase a recovery cd for your computer.
