Windows 7 DVD ROM issue!

[autigerfan]

HP dv 9728, AMD Turion 64 x 2, NVIDIA nForce 560, DDR2 RAM.

Hello,
I have a hp dv9000 series laptop. I recently installed Windows 7. After installing my dvd/rom is not detected in device manager or under the "my computer" listing. Under the device manager I clicked on the "show all devices" tab andd still no dvd/rom. I did install some free dvd buring software called "Phantom". This DID detect my "e" drive under device manager and my computer.
In the device manager it said i was missing a coprocessor driver. In the my computer it would not recognize that I had a disc and would ask me to insert one. Seeing that this "phantom" software was getting me nowhere I uninstalled it. I have installed drivers from Nvidia. my video card is Nividia nforce 560 series. I have looked on the hp website and discovered that this product series will not be supported by HP for the DV9000 series in regards to Windows 7.
Mechanically the drive does work!
Drivers have been updated, uninstalled, blah blah blah! This appears to be a common problem but after searching the 'net for hours and trying various suggestions there has been no cure - YET! I installed the Windows 7 Ultimate from Vista.
The DVD ROM worked perfectly while Vista was installed.
Thank you in advance.

Have you seen this:

Does bios show your rom? Did you update chipset drivers? Did you try to access it through the F8 safe mode? Try with safe mode. If it works try to update its firmware.

These links should help, that was a common problem with that DV series:

The link that Arctucas recommended confirmed that hp would not be supporting win 7 on this laptop series.

I went to NVIDIA and the only updates for my mo/bo were audio drivers which I could not install.
Ran windows "fix it" and it told me what I already knew-it could not detect the cd/dvd device.
In the BIOS the dvd rom was not showing, only the 411 for the mo/bo. Also did safe mode, and the dvd rom was not detected either.

Some one suggested a few things which I tried:

1.to uninstall the ATA channel 0 and ATA channel 1 drivers. did that, still nothing.

2. went to microsoft website and tried to delete the upper and lower filters in the registry but
that option was not there.

3. it was also suggested that I download and install a program called "CD GONE" which was apparently to fix the registry but after reading the readme file, the last update for this was 2001 so I just left that alone.

4. On a few files yesterday I ran compatability mode on a few file ex. a mouse driver update from HP that would work on Vista. I was able to get the .exe file to run and install using this mode.

On a quick side note, the other nite I was replaceing my touchpad/mouse. During this I did disconnect and reconnect the dvd rom drive. Hey the problem was already there so I thought it making sure it was connected properly would be a good idea.
