I am trying to burn the ISO image file that the Windows 10 Media Creation Tool generated onto a standard DVD-R disc. The problem is that the ISO is about 150 MB too big for the disc I am using. I have tried using Nero 12, IMGBurn, and the built-in Windows ISO burning tool on my Windows 7 Ultimate 64-bit main machine and the same problem occurs with each. I have an LG WH16NS40 Blu-ray/DVD/CD burner/rewriter. I have tried multiple blank discs and none of them work. I really do not want to waste a blank Blu-ray on this, nor do I want to have to dedicate an expensive flash drive to it. Has anyone else solved this issue?

    The file size is variable, depending on which options you select, somewhere between 3 & 6GB. It's always been recommended to use a USB key - dirt cheap these days... & re-useable. – Tetsujin Mar 1 '17 at 18:32
  • I really don't want to waste a flash drive on this. I wouldn't trust those cheap generic ones for an OS boot disk, and I am not paying $10 or more for a good one, just bootable OS install media. – Rich Sensale Mar 1 '17 at 18:39

    'Waste' seems a peculiar word to use for a device that's eminently re-usable... if you really want to do it on DVD, then you need double density – Tetsujin Mar 1 '17 at 18:44

    Restrict yourself to a single architecture (either x86 or x64) and it'll fit. Official ISOs (not what the tool creates) are always single-architecture. – Daniel B Mar 1 '17 at 21:50

    As Daniel B already implied, utilize the Windows 10 Media Creation Tool and select just the 64-bit version: https://i.stack.imgur.com/HKzBn.png. Windows 10 Pro will be included, an it will fit on one DVD: How to Download a Windows 10 ISO File. – Run5k Mar 1 '17 at 23:57
