driver issues installing win 7

I'm attempting to install windows 7 ultimate on a desktop. It's a dual core AMD, 2 gigs of ram, etc. It has a DVD drive out of a HP a640N, which HP says is a Philips DVD8401 (this is a IDE drive, not SATA). I mention this because after I select my language and keyboard type, after it says "starting setup" for a very long time, I come to a screen that says "A driver for a CD/DVD drive is missing, please insert a USB drive or CD with the driver on it" or something to that effect. I have tried downloading all the drivers from the HP site and putting them on a DVD and having it search that, but to no avail. I am rather confused to how it can't find a driver for a device it is seemingly using just fine.
I have installed win 7 from this DVD before with no problem on my HP Tx2 tablet, so I doubt it's the DVD.

Any suggestions would be much appreciated! Thanks.

Here are pictures of the two places it is hanging up and taking forever to get through, and the spot where it runs into the driver issue.

Is this a final version of Windows 7, i.e. RTM? Did you burn the DVD yourself?

I have seen many instances of that error caused by a bad burn of the install DVD.

If you are burning it yourself, I recommend an program called IMGBurn and burn at a speed of 4x or less.

There was, in the beta stages, a problem similar to this with Gateway computers (?). As you have used the DVD succesfully, on another computer, and it is starting the installation from the DVD, I doubt it is a bad burn.


Are you able to access the computer by any other means?
If so, try this. Make a small partition, enough to handle the DVD contents and its expansion (say max 20 gbs for surity) Create a folder on the new partition, and call it "Setup". Dump the entire contents of the DVD to the new folder. Now run setup from there.
