Loss of disk space despite clean install

Yes, I press enter. No error message or anything, but W10 then booted with my usual screen saver. It seemed like that shouldn't be what should see.

You are correct, it's not. How did you make the DVD? Try to list as much as you remember. Where you got the ISO. What software/procedure used to burn the ISO to the DVD. That sort of stuff.

I downloaded the ISO file from Microsoft as instructed in the tutorial. I saved it to my desktop then went into file explorer and right clicked on the ISO file. I then asked to burn it to a DVD and asked to verify the disk.

What you did was intuitively correct, but wrong type of burn, depending on how you did it. What you ended up with is a copy of the ISO, in whole, on your DVD. You did a DATA burn, not create a bootable DVD. If you put the DVD in your machine right now and just open it, you will see the ISO, all 4GB of it. Please verify that before the next step, please.

If that is the case, I want you to get a copy of IMGBurn from MajorGeeks and install it. It is widely used and safe. It will create the correct image on your DVD. You will need a freash DVD, unless you are using re-writables.

Download ImgBurn - MajorGeeks

Verify the contents of the DVD you have first, please.

P.S. - could you please tell me what tutorial you read to get the ISO downloaded.

What I have on the disk now is ESD-ISO which is 4.37 GB. I am looking for IMGBurn and will get back in a few minutes after downloading it. I will also need to download the ISO file again as that disappeared when I did the reinstall. The DVD is a re-writable disk, but I think I'll use a fresh one to be on the safe side.

I understand. Yes, the ISO would have gone bye-bye. Smart to use a fresh one (no offense to my buddies who love re-writables :)). Take your time.....

As an alternative to IMGBurn, there is a built in Image Burner if you prefer. IMGBurn is preferred.

I have downloaded and installed IMGBurn, and have downloaded the W10 ISO. I looked at the tutorial you gave me a link to. That's what I used when I burned my current DVD. The files listed on the drive include boot, efi, sources, support, autorun, bootmgr, bootmgr.efi and setup. Is this correct? I have not yet used IMGBurn to create another disk. Let me know what I should do next.

Those do sound correct. Did you say earlier that your system was Legacy, not UEFI?
