Windows 7 - 7 RC 64bit CD/DVD device driver missing!!

What's going on?
The install says a driver is missing.....

I'm getting a unknown hash on the iso I got fro M$.......wtf?!

It might be a corrupt iso I downloaded.
The hash ain't right.
I'll dl it again and see what's up.

I also received this error when installing Windows 7 RC from a USB stick on my Samsung NC10. I compared the total size of all files on the USB stick with the original contents of the ISO image and they were different, and it wouldn't let me copy the files from the image again with errors. Evidentally the download corrupted, and so I re-downloaded and this resolved the issue.

Thanks for the tip!

Yes I re dled the iso too and all was well.
I dont know what M$ gave me the first time but it had the old green bar on the start up of the install, the second dl was the right one with the glowing windows trademark, wierd..
But yes it was the MD5 mismatch that resulted in the error, sorry for my own stupidity not to check it right after it downloaded.

I am having the same problem with 64bit, but my hash is correct. I've tried using all the MB drivers that should load the proper drivers if it was needing SATA drivers.

I've tried with both a SATA CD/DVD and with a IDE CD/DVD drive, both give the same results.

Windows 7 Beta worked fine, no problems at all.

Any ideas?

I found the solution over google–there lies the windows7 iso burner tool; and it solved the problem!
