Unable to Install Windows 7

Recently needed to reformat a laptop with Windows 7 Ultimate 64x from a flash drive.
It's an HP Envy 4-1030us 14" Ultrabook

The hard drive wasn't showing up in the list of drives to install the operating system on so I was able to get the SATA RAID driver onto the same flash drive. However when I go to install this driver I get the following error after trying to load the driver

"To continue installation, use the Load Drive option to install 32-bit and signed 64-bit drivers. Installing an unsigned 64-bit device driver is not supported and might result in an unusable Windows installation".

Is there any way to get around this Microsoft policy? I need to get this driver installed during the install so that the drive is visible to install onto.

Thanks!

Can you set AHCI to Compatibility Mode in the BIOS. This would likely allow you to install Windows. You can set it back later.

Do you have a Windows 7 Install DVD? You could be a bootable USB DVD reader and install that way. The Windows DVD may have more drivers.

The first way is preferable if you can change the setting.

First I downloaded the correct file from Hp

which is an EXE which cannot be used using the f6 routine
Using winrar I extract the files from sp567222.exe
and lo and behold there is an f6 directory I then copy the contents of the x64 directory to the flash drive and I now have the signed drivers ready for the machine

contents of the f6 x64 directory

There is no reason to not use AHCI as the signed drivers do exist. but not if the user just puts the .exe file that contains the drivers on the usb stick.  They have to be unpacked and voila f6 signed drivers are there. All nicely signed by Intel

I downloaded the SP off of HP's website and extracted it as directed. Copied the X64 folder over to the flash drive and it lists the driver:

Intel (R) Mobile Express Chipset SATA Raid Controller (C:\x64\iaStor.inf) (x64)

When I click next to actually load the driver it comes up with the same error about the unsigned driver.

I am not seeing any options in the BIOS to change the hard drive mode. The BIOS is InsydeH2O Setup Utility Rev. 3.7

Can you get recovery media from HP for this?  That might be the best way.
