Windows 7: Windows 7 Installation problem

I got problem just in the beginning of the installation. After I click Install now (on the first screen) it showing me up a new window with text: "Select Drivers to be Installed". Installator is scanning for drivers but can't find anything and don't give me to click NEXT button. Can you help me what to do ???

What build are you trying to install?

I've personally had no screen stating searching for drivers

Windows.7.Build.7068.x86.ISO This is the all name

The window's notice is:

A required CD/DVD drive device driver is missing. If you have a driver floppy disc, CD, DVD or USB flash drive, please insert it now.

Help what that is meaning o0

I would think to download another copy of Windows 7 as that name is too short & could have been tampered with. The real 7068 is
7068.0.090321-1322_x86fre_client_en-us_Retail_Ultimate-GRC1CULFRE_EN_DVD.iso
Did you burn the ISO to DVD or extract onto hard drive? If burn to DVD you might need to do it again at a slower speed as there may be data corruption which is causing the files not to load properly.

I've downloaded 7077 i will try to install it now. Thanks for now
