Originally I got this laptop with VISTA 64 bit installed having all drivers working as expected.
I then attempted to get Windows XP home on same laptop. In brief, I partitioned hard drive using VISTA computer management tool. I made a new partition for XP on drive F keeping with C: Vista, D:HP recovery and E: CDROM. So windows XP was successfully installed. I used Windowsbootpro tool to fix the MBR problems. Now I am able to select either of OS to boot.
After getting XP, I saw that the device manager was showing all drivers red. Now please note that HP support will not be usefull to fix it. AS far as I see, HP unfortunately do not make any drivers for DV7-1245 DX. They only provide for VISTA. However they do for DV6-1245 DX. I tried these but no success.
Then I looked individual drivers. My main driver was to get Networking card, so that I can connect to internet. I was able to get Realtek network driver. Then after connecting to internet, I was then able to go update.microsoft.com and successfully got Windows service pack 3, which installed few drivers. Now I have taken every latest update from Microsoft, all custom HW and SW updates, but I still see "Base Controller", Ethernet Controller, Video and some USB interface red.
Where can I get the rest of drivers?
