Windows 8.1 installation: Which drive is the F drive?

1

I am doing a clean install of Windows 8.1 on an old PC. It was purchased as download from Microsoft Store and written to and booted from a USB flash drive.

It went through all of these steps:

  1. Copying Windows Files
  2. Getting files ready for installation
  3. Installing features
  4. Installing updates

Then at "Getting finished" I am stuck at this stupid dialog box.

Please unplug the following external drive and click OK to restart your computer and finish installing Windows.

F:

How do I tell what physical drive this is? Can I drop to command prompt during installation? And is it safe to unplug it while powered on?

There is no external hard drive connected, none that I can see. There is no USB or FireWire drive connected externally. I think it sees one of the internal drives as external... in some weird way?!

@and31415 Thanks! It's getting devices ready now. The problem was the USB flash drive that I used to boot and install the system from. The main problem was figuring out which one is the F drive. You can post your comment as an answer, I can update it with the output from the wmic command. – Samir – 2014-05-28T09:39:13.387

Answering myself: those letters should be associated with empty optical disk drives (ODDs). – and31415 – 2014-07-26T13:30:36.453

1It was that "ESD-USB" device that was the problem. That's the bootable USB flash drive I created to install Windows. I just removed it and was then able to reboot and complete the installation. The Shift+F10 shortcut was the solution. I knew about the wmic command, I actually learned about that a few days ago when I needed it. But I had forgotten about the shortcut to drop to command prompt. Thanks again! – Samir – 2014-05-28T09:55:54.867

@sammyg You're welcome. The output leaves me wondering what are those K: and L: letters associated with. – and31415 – 2014-05-28T09:57:25.083
