UUP to ISO - Create Bootable ISO from Windows 10 Build Upgrade Files  

Bernievink said:

I am trying to find out if this creation of a fat 32 partition is a weakness in the original build 16281.
or is it something caused by the way UUP to ISO creates the ISO from the ESD files ?

There's nothing wrong with the tool.

In your case ALL partitions looks exactly as they should, since you are using GPT partition scheme. The FAT32 partition must exist, or your system won't boot at all.

Update: only thing not quite right is the location of the recovery partition, which should be in the end of your HDD.

...I guess a new imaging program will have to do...

Yes, exactly as MS is recommending!

Download Macrium Reflect Free. It's very powerful.

Please do not take this the wrong way.

No problems, you have an issue and post about it, how could I take it wrong?

Anyway, I have not used Windows own backup in about 10 years. As so many other geeks here at TF, I rely on Macrium Reflect.

Having said that, your issue has nothing to do with UUPtoISO tool or your install media made using it. Your screenshot shows you have a default partitioning scheme, system disk partitioned by Windows setup exactly as it should be. A 499 MB WinRE partition (must be NTFS), followed by 100 MB EFI system partition (must be FAT32), and a 16 MB MSR partition (Microsoft Reserved, not formatted), and finally Windows partition.

That is how it should be, how Windows setup partitions system disk on UEFI / GPT machines. Windows native imaging cannot create an image from a GPT formatted disk, exactly because of the error you got: the EFI partition is FAT32, and you cannot even exclude it from backup. As screenshot shows, the selection box is greyed out, it really can't be excluded:


Windows Backup and Imaging can only be used to backup BIOS / MBR machines. In your case you need to use a third party backup tool.

That is something that has always puzzled me: Microsoft recommends placing the WinRE partition after C: drive (EFI, MSR, Windows, WinRE), but if you install Windows 10 on a UEFI machine letting Windows setup do the partitioning, the WinRE will be placed as volume 1, first partition (WinRE, EFI, MSR, Windows).

That's why I use a DISKPART script to partition system disk whenever clean installing Windows on a UEFI / GPT system. Here's a sample DISKPART script:

Code:

rem DISKPART script, all available space to C:partition
rem ---------------------------------------------------
rem Select Disk 0, wipe it empty, convert to GPT
rem ---------------------------------------------------
select disk 0
clean
convert gpt
rem ---------------------------------------------------
rem Create & format 100 MB EFI System partition 
rem ---------------------------------------------------
create partition efi size=100
format quick fs=fat32 label="System"
rem ---------------------------------------------------
rem Create 16 MB MSR partition (will not be formatted)
rem ---------------------------------------------------
create partition msr size=16
rem ---------------------------------------------------
rem Create Windows partition using all available space
rem ---------------------------------------------------
create partition primary
rem ---------------------------------------------------
rem Shrink Windows partition to make space for WinRE 
rem ---------------------------------------------------
shrink minimum=450
rem ---------------------------------------------------
rem Format Windows partition, label it, no drive letter
rem ---------------------------------------------------
format quick fs=ntfs label="Windows"
rem ---------------------------------------------------
rem Create & format 450 MB recovery partition 
rem ---------------------------------------------------
create partition primary
format quick fs=ntfs label="WinRE"
set id="de94bba4-06d1-4d40-a16a-bfd50179d6ac"
rem ---------------------------------------------------
rem Exit Diskpart 
rem ---------------------------------------------------
exit

To run above script, boot from Windows 10 install media, press SHIFT + F10 to open Command Prompt, run following command replacing Z:\DiskConfig.txt with actual path to your script:

DISKPART /s Z:\DiskConfig.txt

Close Command Prompt and proceed with Windows Setup.

Thank you Kari and all the other helpful people.
I guess all the machines I have set up over the years have been MBR as this was my first failure (GPT system)
I will try both Acronis and Macrium and see which I like best.

Macrium Reflect Free is free, and is fine for most users requirements.

Acronis is not.

Forum members here overwhelmingly prefer Macrium and many great tutorials on it by @Kari in tutorial section.

I actually paid for Macrium Reflect Home as it has Rapid Delta Restore.

In the OLD days, I used to use Acronis and similar, but now I prefer Macrium, because it's FREE and much better in every way, in my opinion. If you need more features than the free edition can offer then do as @cereberus did and purchase a HOME license. Then you have a really powerful backup tool. :)

I don't know if they fixed it but Acronis had problems with UEFI.
