Well, there's a guide how to make a Windows 10 using AMD discrete graphics on this laptop.
Some tools/drivers are required^_^
UBR tool, to get valuable info from your machine, which is required to make every function to work properly. I've uploaded it
hereDDU (Display Driver Uninstaller), to properly remove windows default drivers, can be downloaded from their official website:
https://www.wagnardsoft.com/And latest Leshcat Drivers for old AMD GPU's. Grab it from his
repositoryAdditional note - download drivers which you might need before you start installation of Win10^_^
First step is to get back to Windows 7, install minimum set of drivers (to make sure that everything IS working properly). Original drivers have to be downloaded from official HP's website. Install, as i said, bare minimum of drivers - Intel's chipset, Media Engine, Intel's GPU and AMD's GPU, and "Nothing else matter".
After you installed everything i've said above, you have to run UBR tool. You'll see something like it:
Write down anywhere you feel comfortable two sets of data - {CurrentControlSet Intel} and {ControlSet001 Intel} In my case it's
f840 for both, your machine might shown different values. These are required to make all graphics workng properly after Windows 10 installation (like sleep mode, brightness control, etc). Keep them in safe place in case if you have to reinstall Windows. They are working with Windows 7/8.1/10.
Second step is - install Windows 10. Be sure that your laptop IS in offline mode - no ethernet nor Wi-Fi connection is allowed! You can use Windows 7 x64 drivers for most of internal hardware. But install minimum set of drivers first - Intel's Chipset and Media Engine. Then you have to prepare your Leshcat drivers. Run it and you'll see a startup menu. Check in it's configuration window that you have marked all required stuff, like Intel and AMD's drivers and let it extract all required files.
Third step is to run DDU tool. When you launch it it will offer you to reboot in SAFE MODE. Do it. When in SAFE MODE DDU will restart istelf and you have to:
1) Remove AMD Drivers (without restart or quitting DDU!)
2) Remove Intel Drivers (with reboot, which is recommended).
After laptop reboots go to folder with previously extracted Leshcat drivers and run manually Intel's GPU drivers. There will be 2 folders, don't let them confuse you, you need the set for Windows 8.1/Windows 10. After installation it might ask you to reboot, it's okay to do that.
BUT BEWARE! You have to configure Intel drivers before proceeding further^_^
Run UBR tool again. There you have to press {J} button and tool will ask you to manually input configuration data (f840 for my machine, possibly different data for yours!) twice - {CurrentControlSet Intel} and {ControlSet001 Intel}. It can be identical values for both or different for each other. Then tool will ask you to reboot to apply these values.
After reboot your system have to work properly in normal mode, after you put it in a sleep mode and wake up.
Fourth step is to install AMD's drivers. Back again to folder with extracted drivers, run SETUP and follow instruction. It already configured, so just run it and proceed with it till the end. Can't remember if it will or not ask you to reboot, but do it anyway, just to be sure that everything installed properly.
Technically, if everything went fine and all internal hardware is perfectly working, you've done hardest part of the job and now you can use AMD discrete graphics on Windows 10.
Just install all required drivers for other hardware and you can safely get it online to update Windows.
Be aware - depending on installed cardreader in your laptop (Realtek definitely won't!) it might or might not be working with Windows 7 drivers. In that case let me know, i'll upload for you the drivers which i use on my DV7 with Win10.
P.S. - as i said on your youtube channel, you can upgrade laptop's CPU to a better one. But check Service & maintenance guide first. You can check for it on official HP's website. My DV7-6152er has Core i5 2410M installed. After some soldering (i've soldered in parts for third PWM phase of CPU power supply and now is able to use quad core cpu's) and i'm using i7-2820QM which is wa-a-a-ay better^_^
By the way, i also tried i7-2630QM and it sucks. It's just a bit better than i5-2410 i had before.
One more thing - this motherboard
can be upgraded for 2GBytes of GDDR5 VRAM.
