I currently have Windows 7 build 7000 (32-bit) and Windows Vista (32-bit) installed, and I am looking to install Windows 7 RC (64-bit) and erase the other 2 OS's. I am booting from a DVD and am getting the following message:
"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.
Note: If the Windows installation media s in the CD/DVD drive, you can safely remove it for this step."
My setup is:
AMD Athlon 64 X2 4200+ Processor
Asus A8n Sli Deluxe motherboard
EVGA Nvidia 8800 GTS 512mb
320GB WD HD, 1TB WD HD
2x SONY 16X DVD±R DVD Burner Black IDE Model DWQ28A
I tried unplugging my TV tuner, secondary HD, and all unnecessary USB components as suggested in another answer, but I am still getting this problem every time I try to run the setup.
I put in the motherboard cd and have browsed to every folder, and tried installing any driver that came up to be compatible with my system (which was very few). After I pressed next, it said that no new devices were discovered and brought me back to the original menu to find more drivers. One driver returned the following error:
-The Nvidia CK804 ADMA Controller (v2.7) device driver could not be installed. Contact your vendor for an updated driver.
I also tried inserting my graphics card cd and it returned the following error:
-The Nvidia GeForce 8800 GTS 512 device driver could not be installed. Contact your vendor for an updated driver.
I figured this problem may be resolved if I tried booting from a flash drive instead of the DVD, but I was unable to get all the necessary components for 64bit Windows 7 onto the flash drive under a 32-bit Windows 7 environment.
I tried creating a virtual machine in VMWare and I had the same message saying:
"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."
Thanks for you help! I have spent countless hours on this already.
