Windows 10: My newly built PC keeps rebooting into Windows Setup in a loop when trying to install it...

Tl;dR: My PC keeps booting into Windows Setup or saying "Reboot and select proper Boot device or Insert Boot Media in selected Boot device and press a key". I don't know what else to try.

I built my first PC yesterday and so far it seems like the hardware is running fine. However, whenever I start it, it keeps booting up the Windows Setup to install it.

When I "install" it, and it actually works, it just restarts and boots from the USB Drive again. I used the official Microsoft Tool for the first time, and Rufus on s second USB drive as well the second time. I am slowly running out of ideas what to do, I think I've spent about 12 hours yesterday trying to set it up. My Specs are:

• 
  Motherboard: MGB MSI z390 Gaming Edge AC
  
  
• 
  CPU: i7 9700k
  
  
• 
  GPU: R9 390 8gb
  
  
• 
  SSD: Samsung Evo 860 250gb
  
  
• 
  RAM: 16g 3200mhz
  

Here is a list of things I already tried

• 
  Format the SSD so I can load windows ontonit
  
  
• 
  Format the USB Drive and install the Official Windows Installation tool on it
  
  
• 
  Format a second USB Drive and use Rufus on it as well
  
  
• 
  Flash my Bios to the latest version
  
  
• 
  Use Bios Default Settings
  
  
• 
  Change Bios Default Settings from CSM
  

Legacy + UEFi to UEFI only

• 
  Clean the SSD using Diskpart, then creating a partition, marking it as active and assignint it while using default settings
  
  
• 
  Cleaning the SSD again with Diskpart, then converting it to GPT and creating a partition, marking it as active and assigning it
  
  
• 
  Switching Cables and SATA Ports for the SSD
  
  
• 
  Pulling out the USB Drive while the PC restarts after installation
  
  
• 
  Marking the USB Partition as active and setting it to boot first
  
  
• 
  Pulling out the USB Drive and then putting the SSD as Boot Priority
  

However, if I install Windows, remove the USB Drive and then start up again, all I see is

~Reboot and Select proper Boot Device or Insert Boot Media in selected Boot device and press a key~

When I then insert the USB Drive again, it shows that there is now Data on the Partition.

I honestly feel like I ran out or options, is there anything I can do?

Endless reboot loop

Hi Joanne,

If your PC is in a reboot loop state, there might be a component of Windows that is broken or damaged. We recommend that you use the installation media you have to reset your PC. Here's how:

• Connect the installation media to your PC, and then turn it on.
• On the initial setup screen, enter your language and other preferences, and then select
  Next.
  • Note: If you're not seeing the setup screen, your PC might not be set up to boot from a drive. Check your PC manufacturer's website for info on how to change your PC's boot order, and then try again.
• Select Repair your computer.
• On the Choose an option screen, select Troubleshoot. From there, select
  Reset this PC to reinstall Windows 10. This will remove apps and drivers you installed and changes you made to settings, but lets you choose to keep or remove your personal files.

If you need further assistance, feel free to ask us.

 

Creators Update: Built-in Administrator Account stuck in setup loop

never seen this one before, folks.
I'm trying to repair software problems with a HP x360, after Creator' Update. Apparenly the built-in Administrator Account was never setup. I invoked it "active" rebooted and accessed "Administrator" in safe mode.
It has been looping for an hour now, finally losing most of the video display - only the cursor is visible, or the trace of a touch on the touchscreen.
Anyone seen this before and what is the cause & remedy? The disk light just keeps on rolling as it tries in vain to setup
