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?
 
A friend of mine had this and it was because of a corrupt download, but it could also be a bad disc. Can you verify the MD5/SHA1 hashes of your ISO?
 
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?
 
Hashtab plugin for Windows.

Then just check the MD5 with the know MD5 hash of the build of Win7 you have.
 
I had a similar issue when installing WinXP a while back, only way I got round it was by using a different DVD drive. Seemed pretty stupid to me as it could load up the setup part from the disk, and the drive worked fine when I swapped it back in afterwards.
 
Yeah sounds like a corrupt image, MD5/SHA1 the ISO file you downloaded then make sure you enable 'verification after burning' in your burn program to check the disc has written correctly.

You can also extract the ISO to the root of a USB storage device and try and boot off that.
 
I use HashMyFiles for the hashes; it's pretty simple to use as well. Either Google the hashes yourself or post them up here, as LewisStuart says you should get lots of results.
 
I know it's a pain, but can you try and install it in a virtual machine using VirtualBox? You can either load the ISO directly into VirtualBox or make it use your burnt CD. If the error still comes up within that it's likely to be a bad download/disc again unfortunately.
 
I had to use an external DVD drive to install on my laptop, it would just freeze half way through on the built-in one. You've said you tried installing from a flash drive though so I have no idea.

If you downloaded with the MS download manager, I'm fairly sure it verifies the file once its downloaded so it shouldn't be a dodgy download.
 
MD5: 0ce886bfc9a0c725ffb1f43059f21ca8
SHA1: 276789615fc4b3a5524b83b8faf8b2bd35bcf15a

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?
 
have you already got a working OS on the laptop? you could try running the installer from a mounted ISO

i had the 7000beta and the RC running fine on my dell d620 (one with the NVS gfx) but id not used an actual disc to install em. it ran perfect. really speedy too even on a 1.66ghz
 
Link just redirects me back to the W7 homepage. Did it download through a java plugin or just the standard internet browser file saver thing?
 
Have you checked to see if there is a DVD drive driver for your laptop.... maybe it could be that it actually need this?!
