Pavilion dv9000 will not boot up to OS or from CD need help

[intrepidimage]

I was trying to downgrade Vista Home to XP, but in doing so I misread a couple steps and installed XP drivers for the chipset and BIOS (instead of putting them on a new WinXP install disc including the drivers).  The Notebook would make it to windows and boot from the CD drive before but only sometimes.  Now it won't even come close to Booting to Windows or from the CD drive.  Repair disc doesn't finish, Checking the file system for errors doesn't finish.  I don't think any of the hardware is bad.  If I can just find a way to get it to boot from the cdrom I'm pretty sure I can install XP and everything will be fine, it's just getting it to boot up i'm having a problem with.

HP Pavilion dv 9700 Notebook PC

Intel Core 2 Duo CPU T5550

Product #GP236AV

BIOS F.51

Windows Vista Home Edition

You need to sliptream ICH9 sata sata driver to pass BSOD error while installing XP.

ICH9 sata driver, here

The driver is located in iaAHCI.inf and is called ICH9M-E/M SATA AHCI Controller

Sliptream only ICH9 sata driver, see part 2 of XP downgrade guide, here

I've come across this very same issue and in order to by-pass the boot issues with the MBR (master boot record) on the machine, which seems to be a serious issue on most HP laptops running NVIDIA cards.

You will have to download the proper Acronis Disk Image software. Seagate, Maxtor and Western Digital all have FREE Acronis Disk Image distributions that ONLY WORK ON MACHINES WITH THE PROPER MEDIA DRIVES. So if your laptop has a seagate hard drive then you download and utilize that FREE Seagate version of the Acronis Disk Image software to create a boot disk.

What you will need:
A working computer running windows XP or better.
USB Flash Key/Drive w/1 GB capacity


Now considering your machine, like mine, fails to boot off HD or CD(internal or otherwise), we will move to booting from USB Flash Key/Drive.

Here's the catch 22, if the working computer you are installing Acronis Disk Image doesn't have a drive from the same manufacturer as the hard drive in your laptop. Meaning if you are trying to install Seagate's FREE Acronis Disk Image software because your laptop has a Seagate drive, that's good, but if your working computer (the one you will be creating the boot disk with), doesn't have a Seagate drive the software will not allow an install on that machine.

But considering you get past those pre-requisites the rest is easy. Install the Acronis Disk Image software on the working computer, and once installed go ahead and run it and create a 'bootable disk' on the USB Flash Key/Drive. Now that you have successfully created your USB Drive boot disk you can boot off this using the laptop. Make sure you allow for the USB Drive to be bootable prior to CD or HD, you can do so in bios by hitting the <F1> on the boot screen on most HP laptops and machines.

Here's the link to the resources for those free Acronis Disk Image software titles:
Western Digital Version: http://support.wdc.com/product/downloaddetail.asp?swid=119

Seagate Version: http://www.seagate.com/www/en-us/support/downloads/discwizard

Maxtor Version: http://www.seagate.com/ww/v/index.jsp?locale=en-US&name=MaxBlast_5

Keep in mind, your machine can easily boot off USB CD drives as well, all you have to do is set your bios look elsewhere for boot records. So if you haven't tried this first it might be easier than having to go through this USB Flash Drive/Key setup process.

Hope this helps, took a while for me to overcome to multiple issues confronting my beloved laptop, but I have prevailed and hopefully you will too!

Yet, you will come to find, the most important fix is yet to come: HP (NVIDIA) Re-Balling!
