Wimboot Won't Load System Image Recovery from Windows Repair

[NiKiZe]

(as you noted) bmrui.exe is located in one of the directories that is in your PATH environment variable, meaning that no matter where you are and type bmrui that file will start (searched by the order of the path variable)

This is the same as with for example notepad.exe
So yes bmrui.exe does indeed exist no issue there, you can also see that from the title of the error dialog. So the question is what file it is bmrui.exe can't find.

To test you can try and run "doesnotexist.exe" and see what you get to compare.

I'm assuming this runs on a machine with a disk, with the intent of creating or restoring a image?

What is the partition type of the disk? if it is a GPT partition layout then most windows tools will refuse to work with it if you have started in Legacy. (and the other way around if you boot in EFI and try to do anything with a MBR partition layout) But on the other hand memdisk is Legacy as well so that shouldn't be the issue here.
