Hey there, Asheton.
It seems like you've booted to Windows by using your HDD. Make sure that you select save & exit after you change the boot priority order. You should also try booting to Windows with just the SSD connected to your motherboard, to see if everything works fine.
Please let me know how it goes.
Booting with just the SDD and having the HDD disconnected from the motherboard. My result was the Windows 10 boot spin never stopped.
