I have been trying to install Windows 7 on a Lenovo G50-80 but I keep getting this error message "a CD/DVD driver is missing" right after I have selected language in the install process. I have tried updating bios to the newest version and slipstreaming both the chipset and the USB3.0 drivers to the install disk. I have tried installing from both USB2.0 stick, and a external USB DVD drive. Also when I slipstreamed the chipset drivers I noticed that "Windows Toolkit" claims that the USB2.0 drivers in the chipset are not campatible with Windows 7. No matter what I seem to do or what settings I use i bios I can not get past this driver error. Please help me.

Thanks. We'll let you know when a new response is added.

Got it to work after reading and trying and almost throwing the laptop away.
1. Go to System Restore and then Command Prompt (if windows 8 or 10 is preinstalled, start windows and click start and type System Restore.
2. Type Diskpart, list Disk, select disk 0 (in my case), clean. After that simply type exit and exit and restart to your CD or USB. I am soooo happy now. hope it helps you guys.

    Does the machine have an USB 2 port?  Have you tried connecting the external USB drive to that one instead of a USB 3?

    The laptop has 3 port. Only one of them is blue, so I can only guess that is a USB3.0 while the two others are 2.0.

    Does the installer give you the chance to browse for the missing drivers at that point?

    Yes but I can only acces the internal hdd and the LAN card. All USB including the built-in cardreader are dead after this point.

    Is this a new install or a re-install? Have you tried to change the boot priority to an external drive and see if you can pull them from there?

    It could also happen if the installer media is damaged.

    ToddN2000>> The laptop is preloaded with win 8.1, and I am trying to format the whole hdd and install win 7. I can not do it from and external drive. The usb port do not function after I choose language in the installation proces.

    Carlosdl>> I have tried with 3 different win 7 x64 ultimate isos.

    Lenovo will not offer me support when it's regarding changing OS :-(
    Could it be that the chipsets usb function is not combatible with win 7 as "wintoolkit" claims?

    Why the downgrade in the OS from 8.1 to win 7? just curious as to why you did not like win 8.

    It is not my laptop. But I am not to happy with win8 either.
    The windows OS have not changed much since I was a very young boy. Then came win8 with some pretty radical design changes which leads to a lot of unneccesary headaches. Windows 10 luckily looks like a step back in design. So I have high hopes for the future OS.

    Did you try disabling AHCI mode in BIOS/EUFI? Here's Microsoft's article explaining the issue: https://support.microsoft.com/en-us/kb/952951
