I have a Dell Studio 1440 Model Number PP40L which came with Vista preinstalled. I have followed all instructions in every forum only to be completely stymied. This laptop does not have a built-in CDROM, but I have attached a CD/DVD external drive via the USB port.
Despite reconfiguring the BIOS to startup from either the USB port or the CD drive, the computer constantly defaults to the hard drive, which I then cannot reformat because it is in use. Of course, the XP CD will not let me install XP over the Vista. I understand that I must reformat the hard drive before installing XP, but the damnable machine refuses to boot from the XP CD or from a bootable flash drive that I made.
I sincerely hope that somebody has the answer to this question. I have now spent two entire days trying to resolve this problem.
I was successfully able to remove Vista and install XP on my Dell 1440 Studio laptop, however I now have no sound. I have spent days looking online for the proper sound driver to download that will work with XP to restore my sound.
If anyone knows where to find the correct sound driver, please let me know.
follow the steps below that might help you to downgrade Vista with XP
Step 1 Make sure the new HP notebook has driver for Windows XP Pro. I checked with HP website and yes, there is driver for Windows Xp Pro. So I download and keep the driver in my external Hard Disk.
Step 2 Put the Windows XP CD inside the DVD drive, I restart the notebook.
Keep tapping the F10 key when the Compaq logo appears. This will take me to BIOS Setup Utility.
Step 4 Using arrow key I go to "System Configuration tab".
Step 5 Under that select you will see SATA Native support. The default value is enable, so I disable it
Step 6 Press F10 to "Save and Exit" the BIOS & click on OK/Yes to confirm the changes.
Step 7 Restart the notebook and the notebook boot up from Windows XP CD.
Step 8 As normal, I reach to the screen where I have to select weather to install, repair or quit. I hit the enter key than I get the screen that show the partition. After that I just do as normal and I manage to install Windows XP Pro. :-)
