CD/DVD Driver missing on install  

I found a resolution for this - for me it was do to with a corrupt downloaded ISO image. To check this, I recommend the following steps:

1. Re-download the ISO image from Microsoft
2. Burn new image to DVD at SLOWEST speed, to ensure no mistakes are made.

This will rule out any problems with download or burning which is exactly what caused the problem for me.

The fact that you can't copy the files off the DVD to a flash drive re-inforces the theory that some files may be corrupted. Try comparing total file size of all files in DVD to total file size of all files within ISO image - mine were different which meant some files didn't copy correctly out of the ISO image.

Hope this helps!

good to know also good to hear you got everything worked out ....

I always burn any bootable .iso at the lowest speed my dvd has. (4X) and never have had a issue..so far lol

I ran into the same problem with the missing drivers. None of the suggestions helped much, but if you use a flash drive, you should have no problem. A 4gb drive should do the trick. Just use diskpart to format and set the disk to active, and then use bootsect.exe to make the drive bootable. It's a bit quicker than using a dvd, and it solves the problem nicely.

I found these instructions useful in getting the flash drive set up properly for the install.

I have problem with missing drivers, too. I disconnect cd/rw and boot from flash disc, the setup write missing drivers again, what can I do?

Have you tried my suggestion above of re-downloading the ISO image? It definately worked for me.

I tried it, I tried install from flash disc with disconnect cd/rw, but I have always the same problem.

Okay, i fixed it.


I tried to change my IDE settings (Native, Legacy, etc..), no change in installation.

Then I tried to burn another DVD using slower burn speed, but same installation and copying to USB memory stick issues.

I downloaded the iso file again from microsoft, burned at slower speed and installation went fine, and I was able to copy the contents to my USB drive.

Thanks for all the tips.

downloaded win7 rc on 06/13/09.
After burning image on max speed received "CD/DVD driver missing" problem.

After re-burning the same image on slowest speed (4x vs. 16x) installation went fine.

Thanks

Would that be why I'm getting the message that the installation is missing necessary files need for installation? If I use the DVD in one drive it throws the CD/DVD driver error, but if I put it in my other DVD drive it works fine except for when it starts expanding files.

It'll stay at 0% for about 15 mins, only to tell me it doesn't have the necessary files required for installation. Would that be a product of my burning the disc too fast or a corrupt ISO download?

I had the same problem also.
What i did to fix it was quite easy. Quit the installation when the cd/dvd driver search comes up and press install again. Tested it two times here and the install is flawless then.
