I skipped the setup entirely and went straight from ISO to a fully deployed Windows installation. And it's completely different from what one would usually do to install Windows. Nothing worked, and I could never get past this error.Īlmost on the verge of giving up, I had just one last thing to try. I had tried various different configurations, messing with the BIOS, different ways of mounting and loading up the setup disk, etc. But in my case, my ISO is a perfect download (SHA1 sum matches that provided by Microsoft) and it's mounted directly.

On looking it up on the internet, I only learnt that this indicates a bad setup media. There's no indication why this error is produced and what exactly the device is that's missing drivers. If you have a CD, DVD, or USB flash drive with the driver on it, please insert it now. This could be a DVD, USB or Hard disk driver. As soon as I booted up the setup disk (the ISO I had downloaded) and clicked on Install Now, I received this very unhelpful error asking for device drivers.Ī media driver your computer needs is missing.

I had previously installed Windows 8 RC successfully into a VHD so I knew what I was up against. Hence the decision to install into a VHD, which is a very neat solution that lets me keep Windows 10 TP separate from my real hard disk partitions and still enjoy the full native speeds of my real hardware. At the same time, I also did not want to dedicate a real hard disk partition for the sole purpose of installing Windows 10 TP. While I had successfully managed to install it on a virtual machine in Oracle VirtualBox, I was dissatisfied with the sluggish performance of a VM.

I had been trying to install Windows 10 Pro Technical Preview onto a VHD, as I have Windows 7 Ultimate and can run an operating system from VHD (this feature is apparently limited to Enterprise and Ultimate editions).
