I have bought the education edition of the X1 without Windows being preinstalled and now I am not capable of installing Windows 7 Pro 64bit.
The only option to install Windows 7 is via USB stick, for which I have created a bootable version with the Windows Tool and with a legitimate Windows iso file. But after starting the installation process, the message pops up that necessary drivers are missing, which I cannot locate on the USB stick and which I have no idea to find in the internet. Neither the Lenovo handbook is useful for this first time installation of Windows.
Since I am searching the web now for 3 hours without success I am getting quite frustrated. Does anyone know the solution?
Thanks in advance!

Hello and welcome,
What is the exact message? If it's asking for a CD driver that can mean several things. Usually a bad download or bad media or bad transfer of image to media.
It may be that your USB ports are in USB 3.0 mode and the Windows installer doesn't have drivers for that. I'm not personally familiar with the X1... if it has a USB 2.0 port, try that. There may be a BIOS option to put the ports into 2.0 mode or perhaps "auto" mode that might help. Another option is to connect via a USB 2.0 hub.
Are you installing in UEFI or legacy mode? In UEFI mode you'll need to enable CSM support in BIOS - which may be explicit or may be automatic when you select the "not OS optimized" boot mode before loadingt defaults. (The missing driver message doesn't sound like missing CSM support).

thanks for the quick response.
There are only USB 3.0 ports, I changed the BIOS option to USB 2.0.
I am not sure in which mode I am installing. At the Setup menu it says Both, Legacy First and CSM Support is enabled.
I am not sure about the image, I tried several iso, but none worked thus far.
I will try with a hub, maybe that works!

Make sure USB 3.0 mode is set to disabled then also make sure boot mode is legacy and CSM support, about cd/drive that is because Windows is normally installed via cd which is why installer says it cannot find any drivers for cd/drive so that error you can ignore, what it goes on about is a USB 3.0 drivers is missing but instead it's saying a cd/dvd driver is missing but real missing piece is the USB 3.0

In 3Rd gen you can disable USB 3.0 I got a 3rd gen aswell and in my bios under USB I have USB 3.0 [Enabled] if I select it I get Enabled, Disabled, Auto so all you gota do is pick disable and save the changes and reboot into USB it should then stop alerting about missing drivers one installation is done go back to bios and set USB 3.0 back to enabled and then save the changes and boot back into Windows and then continue with driver Installation.

Guys, it has been a while this question was posted, but I have the same problem and did not see a solution!
I am trying to install Windows 7 Professional with Service Pack 1 on my X1 carbon Type 20BT (3rd gen). Managed to create a bootable USB stick, installed windows, but it is as good as dead - there is no drivers for most of the hardware, starting with the PCI controller, no network interfaces so I can't connect to WiFi, etc.
I looked on the Lenovo support site for various components, installed .NET and system update, but can't figure out the order of driver installation (transfer the drivers from anther computer using USB stick).
Shouldn't there be some bundle for this computer to make it usable on Windows 7?
Any help will be highly appreciated!
