I faced the same issue today [12-May-2018] after Windows restarted during update. It just stuck at rotating dots, there was some hard disk activity for initial 1-2 minutes and after that it went out.. and rotating dots continued.. i waited for 30 minutes or so... in trying to find a fix, I updated my PC BIOS, went to safe mode [there also it got stuck], opened PC and removed old firewire card, disabled peripherals in BIOS, disconnected all cables etc. etc.

Finally I tried to boot from a Windows USB install disk and when I pressed the boot selection key during BIOS boot, I saw that my primary SSD disk had somehow gone down in the list and old hard disk appeared at the top. I had moved my OS to SSD sometime back and my PC was configured to boot from SSD.

I chose the SSD in boot options and bingo! the Windows update screen appeared again from where it had restarted!

So the problem was somehow Windows update made some changes in boot sector that confused BIOS and it was not booting from the primary boot disk!

Please check if this is the problem, make sure you are booting from the right disk, you may need to go to BIOS and again select the right disk as the #1 priority disk to boot.
