I want to install Windows 7 on a Lenovo Thinkpad X1 Carbon 20FB-002LUS. I created a bootable USB stick with woeusb and the Windows 7 installation medium. However, when I boot from it I get a driver error:

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

How do I figure out which specific driver is missing (I'm guessing USB 3.0)? How can I provide the driver?

I have access to a Linux desktop (not intel).

  • How did you create the bootable USB? – GabrielaGarcia May 14 at 22:03

  • That's probably the problem. For better results use the official Media Creation Tool which is actually what you're prompted to use when downloading the ISO from Microsoft. This is the proper way to do it and also assure you're booting it in UEFI mode. Online after a successful installation you should follow the half-backed answer (the link is useful though and you should download all the required drivers for Win7 64-bit before installing). – GabrielaGarcia May 14 at 22:11
  • @GabrielaGarcia The Media Creation Tool doesn't have a Linux version. – Docconat May 14 at 22:14
  • No, it must be used in Windows but don't you have the preinstalled Windows 10? if not and you must use Linux, hopefully Ubuntu/Debian or variants, then I'm afraid MKUSB is the only tool that actually works with the new ISOs Microsoft published: help.ubuntu.com/community/mkusb#Windows_USB_install_drive – GabrielaGarcia May 15 at 0:33

You would have to obtain the drivers from the Manufacture link: https://pcsupport.lenovo.com/us/en/products/laptops-and-netbooks/thinkpad-x-series-laptops/thinkpad-x1-carbon-type-20fb-20fc/downloads?linkTrack=Caps%3ABody_SearchProduct&searchType=3&keyWordSearch=X1%20Carbon%204th%20Gen%20(Type%2020FB%2C%2020FC)%20Laptop%20(ThinkPad)

I would download the chipset (i presume) and extract it using 7zip then provide those files to the installer it should find the correct driver to use from the folder you provide it. You could boot to windows PE and load the necessary files onto a partition (since a USB thumb drive will not work)

  • In case you missed the discussion above, in comments, the point is to make a bootable USB that actually boots correctly. The drivers are for after the OS is installed and booting the installation media cannot have anything to do or depend on an already installed OS. And now that we know the OP doesn't even have Windows installed this half-answer is totally irrelevant. – GabrielaGarcia May 15 at 0:39
  • yea that's fairly well documented using DISM to add driver packages to an WIM file. – Davef May 16 at 1:44
