How to instal xp in compaq cq40 317 tu

you are getting blue screen because of compatibility issue. go into bios (press f2 on start up) and change from sata mode to ahci compatibility mode 'probably in the advanced section). you should then be able to boot from xp cd. remember to get your xp drivers from the hp website.

The stop error code is most likely STOP:0x0000007B because windows XP doesn't have the correct SATA controller driver to install without assistance.

Options:

If available, try setting the SATA controller in BIOS to ATA or Legacy Mode.

If not available, then you will need to download the SATA controller Driver and slipstream the driver into the XP version you are trying to install

you mean you need to downgrade your computer from Windows Vista to XP?
if so is the case, you need to go to the BIOS in the Boot menu, select IDE from ACPI.
put the boot option to boot from CD first or disable Boot from hard disk.
then you will be able to downgrade your computer from Vista to XP.

hmm error on blue page saying windows setup can not complete? ok this sounds like your disk is dirty or scratched. check the disk to insure that its not dirty or scratched. even the smallest finger print can interrupt the installation try cleaning the disk.

To install Windows XP, it is complicated. You need to have the drivers for your Compaq Presario available on another PC so you can copy as needed. I'd suggest going to the Compaq (now HP) site to see if drivers are available. Good luck !

From what you're saying I get that you want to install Windows XP with Service Pack 3 on your computer. Are you wanting to replace Vista, or do you want a dual boot system? Do you have a Vista CD as well if you want a dual boot system? Did you receive any other disc's with the computer that may have a driver set on it?

U can try edit your bios.
If cant, then u have no choice but to integrate the sata driver on your window xp cd...

Hello.

These are the normal steps on desktop computers but
should work in your case too with a fresh installation

Have a bootable operating system disc. Make sure you have set your boot sequence in your bios: 1st-CD, 2nd-Floppy and last Harddisk drive. To go to your bios, when rebooting your system, press your Del key continuosly until it opens you to your bios menu. Save and exit after setting your boot sequence.
