Unable to write Windows 10 ISO file to a standard DVD because it is too large

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?

2The 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 – 2017-03-01T18:32:58.517

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 – 2017-03-01T18:39:43.613

2'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 – 2017-03-01T18:44:31.813

2Restrict 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 – 2017-03-01T21:50:04.823

Any idea where I could find an ISO of just 64Bit pro? A legal one that is. – Rich Sensale – 2017-03-01T23:10:10.157

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.

There is a method to do this by extracting the desired WIM from the ISO manually, compressing it, and then creating a new ISO with the updated WIM file, but I'm waiting for 1903 to officially release to verify that it still works. Assuming it releases on Tuesday as rumors are claiming, I should have a full write-up posted within a few days. – Nathan2055 – 2019-05-14T00:55:59.890
