The ISO file created by the Media Creation Tool will fit on a standard single layer DVD.

Apparently not.


Fine with the Dual Layer.

Not a problem, I keep such discs on hand as never know when will need, better to do it at leisure than when in a panic to get someone fixed.

That says you're burning 5.1GB - that's not the MCT ISO, it must be the direct download ISO with an install.wim. The one the MCT makes is 4.16GB and will fit on a standard DVD. I'm burning one here....

...all done. Windows 11 ISO from MCT burned onto a single layer DVD-RW.

Interesting, I got it from https://www.microsoft.com/en-us/software-download/windows11

If you download the ISO direct from Microsoft you get one with an install.wim in the sources folder. If you download the MCT and run it to create an ISO it makes one with an install.esd. They both contain the same Windows, but an esd uses much higher compression than a .wim. That's why it can (just) fit on a DVD.
