I am trying to install Windows 7 on my laptop from a USB drive. I used the Microsoft tool to make a bootable Windows 7 USB drive and it boots, but when I try to install it says:

A required CD/DVD drive device driver is missing.

How do I get around this?

Might I inquire as to why someone with the name of 'linuxer' is installing Windows? – Ross Aiken Aug 23 '13 at 20:37
It's for work. Otherwise I'd be on linux – linuxer Aug 27 '13 at 20:24

You properly plugged the USB thumb drive into an USB 3.0 port (blue). Windows 7 doesn't have an USB 3.0 driver build in.

So you must add the USB 3.0 driver first to your boot.wim (mount the WIM, use DISM /Add-Driver to add the driver, commit and unmount the WIM) or connect the USB drive to an USB 2.0 port.

That did it! Thanks – linuxer Aug 27 '13 at 20:23

Switch from SATA to AHCI.

Follow the aforementioned instructions for booting into your computer’s BIOS, then check your HDD or storage settings. Turn off SATA, switching to AHCI, and reboot normally, then re-attempt installation of Windows 7.

My BIOS only allows AHCI. – linuxer Aug 23 '13 at 18:52
And just to be clear. I DO NOT have a DVD drive on the laptop, nor do I have an external one. – linuxer Aug 23 '13 at 19:59

More suggestions:

  1. Change boot order so that your USB thumb drive is first
  2. Does this laptop have some sort of RAID set up? If so, that same error message will show up.
  3. Re-create the flash drive (or use a different one) to verify that it's not an issue with your installation media.
  4. Use gparted (I believe you can run it from the Ubuntu Live USB image) to format the drive as NTFS (or just completely remove all formatting from the drive).

A popular cause for this error is Windows Setup losing its connection to the USB disk after getting to the welcome screen. The solution from

When Windows is asking for driver, just click Cancel. You will be brought back to the welcome screen. At the welcome screen, remove your USB drive, insert it back to DIFFERENT USB PORT. Click Install Now again.

may I ask what "microsoft tool" are you using? Because its all the problem caused due to incorrect tool/method used to make a bootable drive.

You may use ISO to USB for your quick and easy bootable usb drive.
