Installation and Upgrade UUP Dump - Download Windows Insider ISO

I think you forgot what you asked.

I simply do not understand, cannot understand why you geeks are using / think you need a third party tool for that.

My last post answered that one. More below.

Kari said:
Is this one of these "because a third party tool exists, I must of course use it" scenarios?

It also answered this question. However, here is more:

It does it all for you - while checking the USB device when formatting (if you tell it to, of course) and setting up the device to boot for whatever type of system you need it to - UEFI, MBR, UEFI with CSM support, dual MBR + UEFI (which boots to MBR mode for both types of systems).....and so much more Kari.

For example - most people, when formatting a flash drive won't wait for a full format, which will reveal errors, but instead use the quick format.

Your mini tutorial works great - and is perfectly acceptable. But for a device with errors? You'll spend time trying to figure out why it's not working - or finally give up and then grab another device.

I use and prefer to use, and will continue to use, Rufus because it does so much more than just 'format. copy.' I don't use it just because it is a third party utility, I use it because it does what I need it to. And because it does it all in the background while I can get other things done.

John, I think you missed my point.

Mini tutorial for creating a bootable Windows 11 USB install media:

Format USB flash drive

Copy contents of Windows 11 ISO to it

Done.

Kari

Kari, the USB flash drive must be formated as a fat32 device, and the copy fails is the install.wim excedds 4 GB.
This can be solved if the flash drive has two partitions :
1. 1GB fat32 partition; copy bootmgr.efi, setup.exe, the efi directory from the Windows 11 ISO, and copy the boot.wim from the source directory of the Windows 11 ISO to the source directory (to be created).
2. ntfs partition marked active and copy contents of Windows 11 ISO to it

That's what I use too - but there's an issue if the install.wim is larger that Fat32's 4GB limit - so I tick the UUPDump box to make the .esd version. :wink:

Which Kari is now doing as well, as mentioned in another thread :wink:

Quote from my tutorial on our sister site Windows Questions:

There’s nothing in the UEFI specifications that prevents booting a computer from an NTFS formatted USB flash drive. In fact, this so-called limitation is entirely artificial, caused by the single fact that manufacturer has not included correct drivers in UEFI. Luckily, most modern computers can boot from a single-partition NTFS formatted USB flash drive, and install Windows 10 from a single partition USB media containing WIM image larger than 4 GB (maximum file size on FAT32 media).

I do it the same way Kari and Bree do. It's faster and you do not need to turn off secure boot in order to boot from the USB flash drive. It's also the exact same format you get if you let Microsoft's own Media Creation Tool make it: FAT32 formatted partition marked as active with the files and folders from the ISO file copied to it that will boot in both legacy BIOS (or CSM) and UEFI modes. Rufus is good for a lot of things. But I've also answered lots of threads asking why the USB flash drive won't boot, and it's usually because the user selected the wrong options in Rufus.

If others prefer Rufus - good on them, it will get the job done. For me, personally, the old fashioned way works better.

This happens when using that service in Windows 11, in Edge browser, with default security settings:

A simple question: Are you saying, that downloading all those files manually, then creating the ISO, is faster than using UUP Dump?

Asking for a friend...

Kari

You stole Bob's famous quote, Kari! :)

Thanks for the tutorial, though. It's much appreciated.

I do it in the most simple way: I format USB flash drive, mount the ISO as virtual DVD, and copy everything from mounted ISO to USB. That's it, a bootable USB flash drive created.

Is this one of these "because a third party tool exists, I must of course use it" scenarios?

Kari

For me, I started out using Rufus, and have just continued because it just works for me.

I did just download your tutorial for creating a bootable flash drive, though. I will be trying that to see if it works for me.

I use what works best for me; it's just the way I work. If your method works better than Rufus, I have no problem using it.

That tutorial on Windows Questions shows how to make a two partition USB flash drive. Smaller FAT32 formatted partition BOOT contains WinPE and some scripts, bigger NTFS partition Setup the contents (files and folders) of a Windows ISO.

In the future, needing USB install media for a new Windows version, just format partition Setup and copy contents from a new Windows ISO to it.

That's the one I grabbed, Kari. You linked to it earlier in the thread. :)

Kari, this is what my post #62 suggests. I developped a PowerShell script with a gui to do this automatically.

What method are you guys using to flash it to USB? Is Rufus considered ok here?

I use Rufus a long time then I switched to Ventoy on my 16gb drive -- too many for an Windows 10 ISO, so I have now an 1x Win10 Install, 1x Win11 Install, and 1x Win10PE. Also it supports Secure Boot.

How do I know this is done? It's been almost an hour. It keeps saying "The operation completed succesfully" but it still kept going... and still going...

***EDIT****

Ok, my bad... now it is really done. I've tried this before but never really got to the end of it until now... haha..
Thanks @Kari for the nice tut!

Adding packages often stays at 69% for quite a long time. Please notice that the whole process can take hours, depending on your hardware. Creating an ISO with all possible editions on my workhorse laptop (System Two in specs) will take anything up to three hours.

A tip to check if UUP is still running: check the Windows Command Processor task in Task Manager:

If it's still running, and you have nothing else running in Command Prompt, UUP is working to create your ISO image. Just be patient.

I was using my secondary machine (i7-4790K) which is my main insider machine.
For first timers like I was, I think it is a good idea to show the "end" screen saying "Press 0 to exit" in the tutorial. :wink:

Kari · Aug 4, 2021

I will add a screenhot of "All done press 0" to tutorial later tonight.

You can temporarily use this image until you capture your own image, or you can use it permanently. It is up to you.

Fastest way to create multiple Insider ISO images at the same time: do them on Microsoft Azure virtual machines. As you can only create one UUP Dump ISO at the time, and I only had one existing Windows 10 VM on Azure, I just quick created a second one.

One is doing the multi edition EN-GB 22000.132 ISO, the other the same in EN-US:

I cannot get past point 6 it just downloads the file which I cannot seem to open any further??

I simply cannot understand you. Download will first be done in Step 8. There is no file downloaded in Step 6.
