It’s not Windows, it’s either a firmware or hardware issue. Windows installs very quickly actually, nowadays, but of course it’s full of ad tracking etc.
Remove the graphics card and any other extras. Just start with the motherboard, power supply, RAM and hard drive. Try install it. It should work. If not, it may be a motherboard issue. You may have to boot into the bios and see if the firmware can be updated, check secure boot, UEFI etc.
Reset the bios to factory and try again.
Once windows is installed. Install the graphics card driver, then shut it down, install the card, move the HDMI over to the card and boot. It should work.
