Windows 7: Downgrading from Windows 8 to Windows 7. Need Driver Help

Downgrading from Windows 8 to Windows 7. Need Driver Help

Hi all, new guy here. I just bought myself a new(well, refurb) HP laptop and absolutely hate Windows 8. Have been trying to get it to install but every time I get an error saying it can't find CD/DVD drive and asks me to look for the drivers. I'm installing Win 7 from a USB flash drive because there isn't a DVD drive on my laptop.

I have no idea what drivers it wants me to find, I'm guessing USB? I really don't know. I posted this on the HP Support forum a few days ago and didn't get any response there.

Any help would be great! I'm going nuts not being able to use Windows 7. Here is a link to my laptop for specs and whatever else you might need:

Hi

Before you trying to downgrade "Windows 8", i highly recommends creating the "Recovery Drive" as per the below tutorial.

According to the official spec ( HP ENVY TouchSmart 17-j023cl Notebook PC Product Specifications | HP® Support ) , your model only came with 4 USB 3.0 ports. Windows 7 won't support USB 3 by default and requires special drivers. I would recommend simply burn the "Windows 7" ISO to a blank DVD and use it to install. You will be able to install Windows 7.

The i7-4700QM CPU and Intel chipset should support USB3.0 under Windows 7 or Win 8.

Yes and no. "Windows 8" doesn't require a driver to be installed for Intel controllers. "Win 7" do support "USB 3.0" but only after installing the driver like this one.

Intel® USB 3.0 eXtensible Host Controller Driver — Why did Intel release two Windows* 7 USB 3.0 xHCI drivers?

In some laptops, USB 3.0 works in both EHCI and XHCI modes. With EHCI mode the controller will work in "Windows 7" as "USB 2.0" ports. When we install the driver, those ports will automatically switched to XHCI which is the true USB 3 mode.

On the other hand, some laptops which are specifically designed to run "Win 8" may not support EHCI mode and you will get " A required CD/DVD drive device driver is missing " message if you try to boot from that port.

It's a Haswell CPU, Haswell supports USB 3.0 natively, I have two Haswell systems, no drivers were needed any more than USB 2.0 drivers were.

As part of my work, i have to deal with laptops from various manufactures which are differed in configuration. As you probably know, USB support is not in CPU but rather in chipset. Also like any other device, USB configuration is controlled by the BIOS ( like SATA modes - AHCI and IDE ). Regardless of the CPU and chipset, OEM can choose to enable or not enable EHCI support. It is like "USB Legacy" mode found in older systems ( If "Legacy USB" is enabled in BIOS, DOS will see and use USB keyboard and Mouse. Basically this setting will report USB keyboard as a PS/2 one to the DOS ). Like that EHCI mode will report USB 3.0 port as 2.0 to Windows 7.

Most of the drivers from the below link may also work with your machine.

Two questions to what everyone has posted:

1. My laptop has has an AMD APU, so will those Intel drivers work? I'm thinking no, but I'm not sure?

2. I don't have a CD/DVD drive in my laptop so would it be possible to use a USB disc drive to install the OS? I'm only asking because if it can't recognize my USB ports now, would it be able to recognize the disc drive via USB?

Thanks again for all the help.

@Britton30
My understanding of USB 3 is consistent with Anshad. Win 8 comes with generic USB 3 drivers from MS but Win 7 requires 3rd party drivers installed. My guess: If you installed Windows 7 chipset drivers for Haswell then the USB 3.0 drivers were included in the chipset driver.

This might help shed some more light on your problem....

Decided to try something tonight to see if it would work. Had an SSD in my OLD Compaq laptop with Windows 7 on it. Put that in my HP laptop to see if it would boot up and load any drivers. It booted fine but would only load a few drivers(touch screen, keyboard, and a few others). After about an hour, I got every single driver installed, including the USB 3.0 drivers. So I copied those USB drivers to a separate partition on that SSD and went to try to reinstall Windows 7 on that SSD(since I can't read from a flash drive). When it asked me to browse for drivers, I went to the exact location of the files and it wouldn't recognize them.

I don't understand why the installer won't load the AMD USB 3.0 drivers, when they work fine when the OS is booted up. I guess I'm either stuck with this copy of Windows on my SSD(and all the Compaq/HP bloatware on it) or I'm stuck with Windows 8.

@ComputerGeek When I checked the System Info, the only thing it found was this:

AppEx Networks Accelerator LWF ROOT\LEGACY_APXACC\0000 This device is not present, is not working properly, or does not have all its drivers installed.

But in my Device Manager everything is installed, so I'm not sure what that is?

DXDiag will be uploaded now.

Thanks again for the help. Much appreciated

Just curious to know, why don't you use a DVD for installation ?.
