Windows 7(Ultimate) setup hangs:"A required CD/DVD drive device driver is missing. If you have a driver floppy disk, cd, dvd, or USB flash drive, please insert it now."

Hi,
first my hardware I'm trying to get installed:
Gigabyte GA-MA790FXT-UD5P
4 WD5000AAKS SATA 500GB drives configured as raid5 connected to the SB750

When I start the setup, everything is fine until I hit "Install now".
Afterwards I'm delighted with 5-10 min. of "Setup is starting", which is followed by
"A required CD/DVD drive device driver is missing. If you have a driver floppy disk, cd, dvd, or USB flash drive, please insert it now."

after that I provide the "ahcix64s.sys" which is the proper SB750 Raid driver.
I tried the versions from: http://america.giga-byte.com/FileList/Driver/motherboard_driver_raid_amd_sb7xx_bootdisk_win7-64bit.exe
and the one from AMD: https://a248.e.akamai.net/f/674/9206/0/www2.ati.com/drivers/WHQL_SB7xx_RAID_Vista_3.1.1540.127.zip
both with the same result: "no device could be found. Make sure the driver files are correct and located on the driver installation media"

Just a side note: I'm installing from a USB flash drive, which has worked already, when I connect a single SATA drive in IDE mode to the Gigabyte SATA chip (jmb322); however this is not my desired config, i need to run the system from the raid.

Regards
Rio

Hi Rio777

Welcome to Microsoft Answers Forum!

 

It seems the issue with firmware or CD/DVD drive. As you are installing windows 7 from USB flash drive, I would suggest you to uninstall the CD/DVD drive or disable it, and then perform the installation. Let us know if you were able to install successfully.

 

To uninstall the driver follow the below steps:

i.                    Click Start, type devmgmt.msc and press enter.

ii.                  Expand CD/DVD and right click on the sub item and click uninstall driver.

 

Once windows 7 is installed successfully, install the latest driver for windows 7 from the manufacturer website

 

You may even try to install Windows 7 from a different device or media and check if that helps.

 

Thanks and Regards:
