1809 Installation Questions

I bought Windows Pro back in the day when 8 came to a sudden end and 8.1 came out with the message that if you wanted a DVD Player, you needed the PRO version. Now, anyone who knows computers knows that I am just an old man who doesn't need the PRO version of Windows at all! I am no IT specialist or programmer and only need a computer to check my email, pay the monthly bills, and keep the computer maintained with security scans, updates, and cleaned up the SSD often.
I have dual sided DVDs that will hold the ISO of 1809 and I am going to order much larger Thumb Drives than the 4 Gig ones I have now. BUT-something is bothering me. I once had to purchase and install a DVD drive for a Desk Top. I bought a Dual sided, among other qualities, and thus the DVDs Dual Sided disk I have now.
Question or the Point of it all!
Do I need a Dual Sided Player for the Laptop to use an ISO? Have computers evolved to the point that all DVD Players will read and write on a Dual-sided DVD? Or will I have to use USB drives to Clean Install this version of Windows? Also, I like to Burn a 32 Bit Version as well, in case of friends having problems. Should I buy a USB Drive large enough to contain both? What size of USB should I buy for single OS or Dual OS? I just downloaded 1809 and it was just under 4 Gig. Will it run a Single ISO on a regular DVD or does it need extra room for use?

It's dual layer, not dual sided. Both layers are read from the same side of the DVD.

(I don't care for recordable dual layer DVDs. They burn slowly compared to single layer DVDs. I have a BluRay burner, and sometimes have used a single-layer BD even when the stuff would fit on a dual layer DVD.)

I don't know whether all recent DVD drives read dual layer, but I'd hope so.

I downloaded the X64 version of Win 10, and the mounted .iso (the same size as what you'd put on a USB drive) was only slightly larger than the .iso itself. It should fit on a single layer (4.7 GB) DVD. I don't know the size of the 32 bit/64 bit version, but I assume that you'd need a dual layer DVD.

I suggest using a USB flash drive, regardless. Installation from a flash drive is significantly faster than from a DVD. (No, I haven't used a stopwatch.)

Let me say THANKS for the reply. I downloaded the 1809 X 64 and it is 3.58 GB. I can't understand why it must run on a DVD larger than a 4.7 GB, but I just suppose it expands when burned from an ISO to a readable DVD OS used for installation! When I was younger and in good health, I would have experimented with this simple issue and had the answer for myself. I just don't feel up to fiddling with the computer anymore!
I think I will try it with a regular 4.7 GB DVD to LEARN something. I will have and have had, the Dual-layered DVDs as I have had them for years. I will also order larger USB Drives though I have NEVER used one of any size!
I just was looking for an answer that I should have discovered by trying it all for myself.
In any case, I think that I can manage to find out what works and what is the rumor about 1809 being so large. The most it can cost me is a DVD, a new package of USB Drives, and some time-if I can hold up!
I am NOT going to install the OS until it has been fixed and ready for release to the Public! Who knows what will be changed by then from the time the thing was early released to the eager beavers.

Thanks for the reply. My Desktop was an Alienware-for the speed only-but it started blowing smoke and before I could unplug it, it died! This Laptop is my Wife's and she only will turn it on to pay bills! Her iPhone and iPad has her attention now! So it is up to me to maintain this thing I HATE! It has 1 SSD 250-GB and I don't create partitions on it. I have thought about trying the ISO "Mount", but I was afraid of messing up the drive too much as I don't know how you could WIPE a single Drive. he only ways I know to wipe a drive requires an OS to run on.
Many Thanks for a very interesting and tempting idea!

For the Dual Layer DVDs, you must first have a Dual Layer Player. Right? I had an old Dell 9150 Demission and had to replace the DVD Drive. I ordered a Dual (Side) as they were called when they came out (for the player that is). I don't think they will work on just any DVD Player, but they may all have that capability now! I remember back in the day when Windows would tell you that you were out of space-please insert a blank CD to continue and to number it number 2! But that was a while back and most of these youngsters would laugh at that! However, it is TRUE!
Many Thanks

One other quick thought. If you are using a 4 GB Flash Drive, why would a 4.7 Gb DVD fail to work? That was the point of my original question.
Many Thanks!
