... uh, yes? I did use the MCT as asked to get the latest install media for Windows 10 Professional, version 1803, build 17134. Of course, something could have gone wrong during the file transfer process. How am I supposed to know that, however?
Yes, I am able to select the flashdisk I used as a bootable UEFI system process (the MoBo itself came pre-installed with Windows 8 and therefore uses a UEFI pre-initialization environment by default), and I have (otherwise not) been successful in launching setup (from which I did completely wipe the harddisk drive and set up the new partitions I wanted, including a 100 GB Windows partition and three mandatory system-reserved partitions) and copying files. After this, it is supposed to then restart to the harddisk drive UEFI partition, this is where the computer starts having issues with getting Windows loaded.
