Installing Win10 from Mounted ISO

And in post #6...

RE:->RBT said:
Also there it appears to be saying to run setup.exe in the root folder? Whereas I read somewhere else today on this forum that X: \setup.exe, is only for in-place upgrade install

This one is for both, as choosing "Keep nothing" cannot be considered different from custom.

RE:-> RBT said:
* but running the other Setup.exe from Sources folder X:\Sources\Setup.exe allows a custom install.

Volume Z said:

This one allows custom install, but custom install only. Upgrade unavailable. It allows, however, installing to another partition.

You have dived into a lot of detail but do not seem to have appreciated the basic distinction between a Repair install [aka an In-place upgrade] and a Clean/Custom install.
- Repair install [aka an In-place upgrade] is run from within Windows i.e. by booting into Windows then running the setup.exe just as you'd run any other .exe file.
- Clean/Custom install is run by booting into the installation media.
All the best, Denis

Thanks to you both for the replies. I appreciate the premise of focus re-direction between In Place Upgrade and Clean/Custom Install and I will hone in on that with more experiments. I guess I got confused with the facet that this (excellent tutorial) link below,
Clean Install Windows 10 without DVD or USB Flash Drive
which said at it's beginning->'This tutorial will show how to do this, how to clean install . . without any external media.'
and then at the section->Part Three: Run Windows Setup from partition on same PC
3.2) I can now launch Windows Setup from the ISO_Files folder which in my case is located on drive D: with following command:
D:\ISO_Files\setup.exe
---
But when I ran the setup.exe (from root folder not \sources) I did not see any option to delete any partitions. In any case you guys have put me on track to grasping more facets of this more than before and I will install a SSD in my spare Laptop and experiment more.
* Edit Add later: To be clear the one area that I deviated from the Tutorial instructions was I merely ran the setup.exe from the Mounted ISO sitting on a spare (non-window) partition. I did not copy the ISO files to a spare folder as the Tutorial said. So in the future I will redo this with the files copied physically out of the ISO and experiment further.*

I did not see any option to delete any partitions

- about step 13/14 in the tutorial
A clean install is normally started by booting your PC from a Win 10 install disk, as per the tutorial...

You boot from the installation media for a Clean install or a Custom install whereas you boot into Windows normally for a Repair install.
That Clean Install Windows 10 without DVD or USB Flash Drive also involves booting into the installation media, it's in Part 2 just above where your link goes to. It must be done before the part 3 your link goes to.

And note this as well since you keep referring to this topic - Custom Install - TenForumsTutorials

You still seem to me to be trying to consider too many things at once.

... running the setup.exe from root folder of image folder structure, instead of the setup.exe from the sub folder named Sources.

None of us have commented on this part of your original post. I do recall the difference as something that was significant in Windows 7 but I have not seen any mention of it in Windows 10.


Best of luck,
And thanks for the rep,
Denis
