During the process to download the ISO file, when it gave me the choice: "Choose which media to use.", I selected "ISO file", not "USB flash drive." So it was not a mistake in selecting the wrong media. I went back and did it again to make sure I had not made a mistake.
Not only you need to increase the size but also eliminate the 15GB partition since the max # of partitions for MBR disk is 4. The 4th partition created will be a logical partition. You'd need to reduce your disk to 2 partitions: System Reserved and C drive then try update again.The size fo the System Reserve partition is no longer an issue. I increased its size to 550MB days ago. It did not fix my problem of Update 1709 not installing.
That seems counter-intuitive. My wife's computer is a twin of mine. Her computer accepted the 1709 upgrade. Her drive partitions are as follows: System--350MB (it seems that it is not necessary to have a 550MB System partition after all), C: partition---1848GB, Recovery partition--14.65GB.
However, her partitions are in a different order as views with "Drive Management" My recovery partition is first on the left, System Reserved in the Middle, with C: on the far right. Her System is left, C: in the Middle followed by the Recovery partition.
Wondering what could be different between hers ( a twin of mine save for the partitions) and mine that could/would cause the manual (not using Upgrade Assistant) update to fail with a reference to a "...USB Flash Drive...", it occurred to me that at some point I changed the boot order in BIOS.
Does that strike you as the possible cause of the problem?

Addendum: Re: The message "...cannot install Windows on a USB...".
I just noticed that when I go to the Windows.ISO file in Windows Explorer and click on "Mount", and when it takes me to "setup", when I click on setup it takes me to the screen where it says: "Do you want to allow this app to make changes to your device?", below that, it says: "File origin: CD/DVD drive." This does not seem correct inasmuch as the Windows.iso file is located on my "C;/users/dahermit/Documents/Windows.iso" ...not a CD/DVD drive.
Ahhh, but the definition of an ISO is a collection of files that represents the contents of an optical disk, such as a CD or DVD drive. So, when you mount an ISO in Windows 10, it shows up as a "virtual CD/DVD." Thus, for example, here's what Explorer just did when I told it to mount a Build 17025 Insider Preview ISO I have laying around: it shows up as the highlighted item DVD Drive (N:)
That just the way Windows 10 rolls, apparently.
