Today I tried to do exactly what you wrote above. First I created 2 partitions named TEST1 and TEST2. Then I wrote down both GUIDs. Then I used the copy function of Disk Imaging to copy TEST 2 over TEST1. The result was that the disk contained 2 partitions named TEST2, but the one that replaced TEST1 did not have the old GUID of TEST1, neither did it have the GUID of TEST2. So I don't see how I can combine the content of one partition with the GUID of another by using the copy function of Disk Imaging.

Are you using traditional mode? Presume so since otherwise it would
copy entire drive. Did you use the change disk id and guids option?
That should be disabled. Email the .log file created to support.

Traditional mode? Copy entire drive? I'm sorrry, but I don't understand what you mean. I did exactly what you wrote earlier:

It appears that the "Change GUID" setting is not important at all, because regardless of the setting, always a new GUID is created when Disk Imaging (ImageForUEFI) is used to copy one partition over another.

Sorry, but I don't know how to do this. I can read the ifu.log file when in BIU, but how can I copy the file to a NTFS partition? I already made an image from the EFI system partition and then tried to open it with TBIView, but apparently that is not possible.

AGH1965,

Double click the TBI file and it opens in TBIView
EFI System Partition
EFI\BootIt

Drag ifu.log onto the desktop.

Thanks Brian, that is what I did, but apparently the image was corrupted. :(

Below you see the section of ifu.log regarding copying partition TEST2 over TEST1. My intention was to get a partition with the GUID of (the original) TEST1 and the contents of TEST2, but instead I get a second partition named TEST2 with a new GUID and the contents of the original TEST2.

Actually I was thinking of the /embrid:0 but the next version will have
an option for using target guid.

I upgraded to BIU 1.16 because I saw that the included Image for UEFI 3.37 would have this option. Unfortunately I can't find the option in the list of options that are currently selectable in the GUI of Image for UEFI 3.37. Is this a command line option only?

Hello,

It's the new option:
Added /utg (UseTargetGUID) option to reuse overwritten partitions GUID.

So you can add UseTargetGUID=1 to the .ini file under the [options]
