Windows 10: Windows 10 Version 1803 x64 2019-08C Update Failure

So, no matter how many times I reinstall windows 10 from scratch, upgrade from 7/8.1, or let my pc attempt to install this specific update, it always fails and freezes nearly half finished. Upon hard restart and a quick automatic system restore, it attempts to update again. Yes, I am aware I can disable updates for a period of time, but I was curious as to somehow be able to install the update so it will stop this endless loop.

When I first contacted you I just wanted to be able to install the update: "Feature update to Windows 10, version 1803 x64 2019-08C" on the system the way it was.

The only problem I'm having with the external drive is with the update: "Feature update to Windows 10, version 1803 x64 2019-08C", which won't install, with the error message: "Windows cannot install on a usb flash drive using setup".

I'll try the media creation tool.

 

Windows 10, version 1803 x64 2019-08C

On my desktop computer, I am using an external HDD per USB as my main drive. The HDD was taken from a previous computer that died about a year ago. At first, I attached it just to be able to retrieve files, but it was automatically set up as a work-station.
Which has worked out even better, and ALL UPDATES, etc., up until now have installed without issue.

My current issue is with update: "Windows 10, version 1803 x64 2019-08C". It WILL NOT install, with the error message: "You can't install Windows on a USB Flashdrive."

Obviously it is NOT a flash drive. Is there some sort of workaround, and/or what can I do???
