Dreaded "A required CD/DVD Drive Device Driver is Missing" window on install

[Guest rcubedcuber]

Hi,

I've been trying to install the RC1 version and get the message shown in the title after the install starts. I have searched the forums and have tried the various suggestions: downloading and reburning the iso image at least 5 times, at different speeds and on different media, limiting the boot device options. I use ImgBurn to burn the image and the verify of the disk shows no errors. I have tried booting from either of the LiteOn SATA Drives in the system

 

I am running an Asus M2N32-SLI Deluxe mobo with 2G of ram and an AMD X2 5600+, 3x500G and 1 TB SATA HDs. I also have XP Pro installed on the machine, but have a 50G clean partition to install the Win 7 into. I have also tried downloading the drivers from Asus as well as Nvidia and letting the installer search for and find the driver. A driver is found, but a message that no new device is found when selecting that driver. The same thing happens on my Asus A8N-SLI Deluxe system (AMD X2 4800+ with 2G). I suspect the downloads may be corrupted. But as other posts have indicated this is (probably) not a driver issue.

 

Does anyone know what the size of the iso download file(s) should be. Mine shows:

 

7100.0.090421-1700_x86fre_client_en-us_retail_ultimate-grc1culfrer_en_dvd.iso 2,097,152 KB for the 32 bit version

 

and

 

7100.0.090421-1700_x64fre_client_en-us_retail_ultimate-grc1culxfrer_en_dvd.iso 2,097,152 KB for the 64 bit version.

 

In some forums it was indicated the 64 bit version should be larger. Both are identical in my case. I am wondering if the TimeWarner has a max limit on d/l file size.

 

Any help would be appreciated. It sure would be nice if MS included a check sum check on the download images as part of the downloads. Other freeware people have done this for downloads of around 200MB. For a 2GB download I would the think the chance of corruption is significanly larger for this size download.

 

Thanks in advance for any help/suggestions.
