Hi:
I am surprised that W7 is looking for a driver for the Intel ICH9M-E/M SATA controller.
See if this works...
Download the drivers from this link below (first or second file listed -- 32 or 64 bit as applicable).
https://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&DwnldID=18668&keyword=F6&lang=eng
Extract the files onto a usb flash drive.
With the flash drive and W7 installation media plugged into the machine, boot from the W7 installation media.
After you select the install now option, select the Drive Options - Advanced menu, then select the Load Driver option.
You should now see the storage driver files listed.
If you check the box, it will only include the compatible driver.
Follow the prompts, and W7 should install.
