Windows 7 64Bit RC1 won't install (missing cd/dvd driver issue?)

Hi All,

I'm trying to install Windows 7 RC1 64bit (clean install) onto my Acer 6930G laptop. My current OS is Vista 32bit.

I've burned the ISO to a disc on the slowest speed, the computer starts booting up then asks me to press any key to boot from the dvd, I do, it moves to a Windows Vista like loading bar (green) scrolling horizontally. After wards it loads up the Windows 7 install screen and says setup is starting. Then a window shows up saying a recquired cd/dvd driver is missing and I need to find it before I can proceed with the install. It gives me a screen with nothing listed and lets me browse the computer to find a cd/dvd driver (I assume) but I can't really find anything. I can even open the dvd with which I burned the ISO but can't continue with the install.

I've tried using an external hard drive as a boot thing but I can't do that either from inside Windows FVista as it's only 32 bit.

Also I tried installing it from a USB drive, exact same error!

Any ideas?

Have you tried that one on some other computer? You don't have to proceed with the install simiply test if you get past the point you get on yours...

There is also a chance you may be dealing with a corrupt download or ISO.

Hello Stan,

This has been documented and fixed for many.

I have had that same problem. I've updated the firmware on my computer to the latest version. No help.
I've looked in the related links at the bottom of this thread, but it only says to retry burning the ISO on the slowest speed. I will try that, but I seriously doubt there was an error with the burn process that Nero 7.0 missed.

I have Lite-On LH-20A1S DVD-RW drive. I'm attempting to install Windows 7 64 bit RC onto a clean drive. However, there is another drive on the system that has Windows XP Professional installed. I think perhaps that other O/S installation could be causing the problem. Anyone else find this error and possible fix? Please don't respond with smart remarks like "This has already been talked about" unless you can point to that specific article.

Thanks.

I had the same issue. Surprisingly, it was fixed by going from a DVD -r to a DVD +r
Won't work for everyone, but worth a shot

And it wasn't a bad iso burn since I wasted 7 DVD -r trying it

I had the exact same issue just now and fixed it by switching my DVD drive (Lite-On) from a 1.5 Gb/s SATA port to a 3.0 Gb/s one. The disk worked for me in a previous install on the exact same computer with a slightly different hardware configuration, so I don't believe there is any problem burning the ISO. I realize this doesn't help you on a laptop, but maybe it can help others on desktops :/

But have not fixed it yet, I didi note that in one of the updates for win7 32 that there was a file that was related to a 64 bit install possibly the missing driver, remember this is not a final version so it will be missing files here and there, so maybe if you upgrade from the 32 version with the latest updates!!! or you could try flashing the bios with a 64 bit version.

Did you guys try changing the jumpers on the DVD Rom?

Many are saying it might be an incorrect download of w7. it didnt prove out in my case altough my first attempt to install poped up the same missing DVD driver as to many.
Also lots are claiming it was something to do with the drivers (IDE or graphics or whatever else).

I used my first and only download of w7 RC (downloaded 7 days ago) which didnt work on my DVD+R Verbatim burned by Alcohol on full speed (that missing driver error appeared). I downloaded free burning soft Active ISO Burner recommended on official MS web. Burned on 8x speed. Also removed my memory stick i had plugged in to my PC during my first unsuccessful install (not plugged in purpose - rather forgotten in my PC). Then tried to install second time and it worked...
My way of fixing solution:
- burning soft Active ISO Burner
- burn 8x
- remove memory stick from your PC
That's all.

franky699,

Just curious, but can you provide a link to where you found recommended programs by MS?
