Problem

Now physical servers don’t really come with DVD drives any more, Im forever deploying Windows, ESX, or some other Linux OS via a bootable USB drive.

I generally use Unerbootin, and just point it at the .iso file and away we go, which I did this week when trying to deploy Window Server 2016. However when I did that, this happened;

Windows cannot open the required file {Drive}:\Sources\install.wim. Make sure all files required for installation are available, and restart the installation. Error code: 0x80070026

Solution

I assumed there was a problem with my .iso, so I downloaded a new one, same problem. I then put the drive in another machine and went to make sure that install.wim was there, (in fact I was going to copy the install.wim from the .ISO onto the drive,) when I noticed something. The install.wim on the drive was 4 GB and the source file was over 5GB.

Only at this point did I realise what was happening! The USB drive is formatted at FAT, and that file is too big to be supported in that file system?

Format the drive at NTFS;

Then recreate it

And Windows Server 2016 installed fine! (I’ll put that one down to experience!)
