Windows 10: What partitions do I need to install Windows 10 Pro Build 1709?

In File Explorer, double-click on a .iso file and it will be mounted as a virtual DVD drive with a new drive letter of its own. You could also right-click on it for a choice of actions, one of which is Mount.

 

Thank you. I should be able to mount the file as a drive following your instructions. Also, I assume it is intended that it is intended that I download the ISO file directly from Mircosoft (no use the media creation tool).

 

The Media Creation Tool does make an ISO direct from Microsoft, in fact it's probably the easiest way to make one.

You choose its 'Create installation media for another PC' option, then let it use its default of 'use the recommended settings for this PC'. Full instructions in Option One of this tutorial.

Download Windows 10 ISO File

Downloading an ISO direct from Microsoft is a bit more complicated, it also means you need to know exactly which of the many choices to download (for example, do you need English or English International, Single Language, the N edition, 32 or 64 bit?).

The MCT does all that for you and makes the right ISO for your PC.

 

Downloaded ISO from Microsoft.

Opened Windows Explorer.

Mounted Windows.ISO.

Clicked on setup.

Windows setup started.

Windows setup aborted with the statement: "You can't install Windows on a USB flash drive using setup."

 

Why is there a usb flash drive plugged in ?

 

Watch the video from this thread for answer:
How to expand System Reserved partition to accept Windows 10 1709. - Page 2 - Windows 10 Forums

 

There is no usb flash drive plugged in.

 

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.
My current drives/partitions:

 

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.

 

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//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.
HTH,
--Ed--

 

I will assume then that the message "File origin: CD/DVD drive.", is just a Red Herring. The answer must be elsewhere.

 

Strange you got that message in reply #17 then.


The Iso file is SUPPOSED to look like it`s in a DVD drive, that`s what mounted means.
