How do I downgrade operating system

Format, reinstall (and make sure there are XP drivers for the HP unit first... if not, you'll be unable to successfully/completely install XP.

Maybe other, better options exist - can you share WHY you want to downgrade?

Hi,

I can't see this machine being designed for Windows XP Pro so whilst you could install the software, you may find you can't get drivers for all of the devices.

Any reason why you could use Win 7 XP Mode or run XP within VMWare?

Hi,

It appears that HP do support XP Professional - all drivers are here:

You could consider a multi-boot environment so you have both Windows 7 and XP Pro rather than a complete format and re-install? You could shrink your main drive to make space for the XP installation, install XP and then repair the PC to restore the Boot sector in order to have a dual-boot system.

First, you have to have a valid license to run XP on this machine.  Second, go to the link tha RobMobility gave for the drivers you need.

You will first need the Storage/SATA/AHCI/RAID driver in order for XP to see the hard drive.  If you don't have a floppy drive/disk to load the driver at F6, then use nLiteOS.com to integrate the driver into your installation media.

Win7 Pro (if that's what is currently on it) should include Downgrade rights.
