Windows 7 Install issues - A required CD/DVD Device Driver is Missing

[TW]Fox · 6 Jun 2009 at 20:31

So I thought I'd try Windows 7 64bit on my Dell D620 Laptop. I was previously running Vista 64bit without issues.

I've not got very far at all before presented with the error:

'A required CD/DVD Device Driver is Missing. If you have a driver disk, CD, DVD or USB flash drive, please insert it now'.

Huh? Surely there is no DVD drive driver issue or it'd not have got this far! Does a Windows 7 driver for something as utterly generic as the DVDRW drive in my D620 even exist? I doubt the Dell website has anything.

Anyone else had this?

Bad disc is a possibility, I've noticed it has a few marks on it. I did manage to copy all the files off it as a test without issue but I guess that doesnt mean much.

Whats the best way to verify the hashes?

Just installing from the USB stick now and... the same error.

I'm guessing I need to redownload the ISO.

ANNOYING.

Any use?

Google finds no results which suggests its wrong? Why does it keep coming down currupt - I've downloaded it twice now from the MS website?
