Windows 10: How to Make Botoable USB Flash Drive from OS Install ISO on Desktop?

I give up. I'm been trying for nearly two days now to make a booable USB flash drive with the Win 10 install ISO on my desktop for the latest Win 10 Upgrade, to the October 2020 version.


Until this version, I was alwasy able to burn a bootable DVD, used Nero. But this version is too big to fit on a DVD, so I have to use a USB flash drive.


In two days of research and effort and trials, I have not been able to get it done. Oh, the ISO is perfectly fine, I used it to do the upgrade.


Oh, I do have the Media Creation Tool, but the stupid thing will not make the USB flash drive from an ISO on my desktop -- why ever would they leave that little function out!? It requires I download the ISO all over again, and it makes the bootable drive from that. It takes me 4+ hours to download that huge file! I do not want to have to do that twice, I already did it once.


This should be a simple thing, easy. In fact, Windows should already have a function in it to do this very thing -- but it does not. I have found various instructiorns with step by step, but they all fail. I know there are various referrals to a few apps to do it, mostly to Rufus, but I dare not touch any such an app I have never heard of and end up very sorry that I loaded some very dangerous malware onto my computer. Why does WIndows 10 not already include such an app!?


Well, I finally did just find what was suppsoed to be a Microsoft app to do it, the poster in a thread here said it would be bootable. It is called Windows 7 USB DVD Download Tool, and despite its name, it is suppsoed to be good for Win 7, 8 and 10. And it is supposed to make a bootable USB drive from an ISO file on your desktop.


I downloaded it, and just ran it. It starts by formatting the drive, and you pick the ISO file you want to use, and the destination drive. That's it, the app does the rest.


It took a while and it finished. I saw the files were on the USB flash drive. I rebooted. It doesn't boot! I tested vit arious ways, but it does not boot. Even though the assurance was that tool would make a bootbale drive, it seems it is not bootable. It seems it merely copied the files from the ISO, did nothing else that is needed to make it bootable.


How can I get this done. Is there not some Windows tool like that one that actually makes a bootable USB drive? But please, I don't want any more pile of steps to do and things to figure out that dont even work. Please, only something simple to get this done.


And shame on Microsoft to not already have that in the OS.

Bootable USB with ISO - What am I missing?

Tried the first program, but it fails .. not sure yet why but troubleshooting that ...

The pendrive seems to be only for linux? although seems very useful i dont think it will help me with this. Keeping it for future linux installs though

hmmm if I already have the iso, do I just throw that in the usb drive?

ok looking into this as well...

 

Best way to OS to iso to install?!

Norton ghost can make ISO's of a HDD but I would just suggest making a whole image and placing it on a thumbdrive cause its faster to install instead of useing a DVD drive.

 

Installing Windows 7 via USB flash drive!

i have been installing Windows 7 Ultimate x86 OEM from my Kingston G2 8gb usb for over 6month now, and it's formattet as NTFS but you need to active the partition on the usb flash drive to get it to boot propperly and give it the barcode that the Windows 7 disc have.

i have use this guide several times but once the usb flash drive's partition is activated you never need to do that again.
