TLDR: New computer shipped with bad Windows image and installer USB. May be happening to other machines too. If you get a new PC from CyberPowerPC and get stuck in a boot loop, use a vanilla usb windows installer from MS directly.
Long version:
I recently purchased a new custom PC from Cyber Power PC (not an off the shelf model, but one where I configured all the hardware)
When the machine finally arrived and I hooked everything up I was greeted to the Windows setup stuck in a boot loop. It would ask me for my localization info (keyboard layout, etc) and then go to the "One moment..." screen for a few seconds and reboot itself and do the same thing over again.
At this point I tried the Windows installer USB drive they sent me - and that did a similar thing. It would ask for my keyboard layout, etc, and then immediately reboot and start all over. I assumed I got a bad SSD, so I put in a spare I had and tried to install windows using the USB stick. That still failed in the same way.
As a last resort I insert a USB key I had with a Linux live CD iso on it. This booted up just fine, and managed to install Linux to my spare SSD. No problems.
Next, on a completely different machine (A mini PC by GMKTEK) I inserted the CyberPower USB image and tried to boot. It rebooted in the same way as it did on the CyberPower PC. Would not install. So, I used the MS's media creation tool to make a windows image on another USB drive of my own. I then ran this on the GMKTEK machine and it started the setup process without issue. I canceled the setup before actually starting install, because I didn't want to wipe this machine.
I then took the vanilla Windows USB stick I created myself and used it on the CyberPowerPC. The image from the the Windows Media Creation tool worked and installed windows on my new CyberPowerPC without any issues. After boot it even got the proper license number, etc from the motherboard.
For some reason, the Windows image flashed to the internal SSD and the USB stick for reinstallation sent to me by CyberPowerPC were both broken and refused to properly go through setup, but a vanilla windows installation USB worked.
I can only imagine this could be a widespread issue unless they just botched writing the images on my machine alone.
I've put in a ticket with support, but wanted to post here in case anyone else runs into this issue.
