Your Windows 10 setup is behaving oddly, and you're facing a tricky recovery situation. It sounds like the system might be stuck in a boot loop or experiencing issues with the USB drive. You've already tried power cycling and switching BIOS settings, which are good steps. The fact that it only shows the Windows loading screen for a long time suggests a possible hardware or firmware problem. Since you have both Windows 10 and Ubuntu USBs, trying one of them might help determine if the issue is specific to your current installation. Consider checking the USB connection, ensuring it's properly seated, and testing with another USB drive. If problems persist, consulting a professional repair service could be necessary.
