Windows 10: Windows 10 restart loop

Since upgrading from win7 to win X, computer has been fine when on, shuts down ok for the night but when I come to start up next day it goes into a continuous loop on restarting fro a short time until it stays on, error that comes up is 0x000021a which I assume is windows update failing to install on boot up (correct me if I am wrong) but I do not know how to go about fixing this. Any ideas please?
I also sometimes get a "interrupt exception not handled" on the odd occasion too

Many thanks in advance

Windows 10 recovery error

Okay i did the steps you linked me to. Now it theres a windows 10 restart loop where it shows the 64% and then it restarts the loop all over again

 

November 25, 2016 - Windows 10 system locked in a blue screen "restarting" loop.

November 25, 2016 - My Windows 10 system must have been updated today because it is locked in a blue screen "restarting" loop. All I did this afternoon was a normal restart and it got into the loop.

HELP

 

I think it has something to do with tweaking the registry. I would link it but I can't at the moment. Search windows 10 update error regedit profile.

 

Resolved the update failure process but from time to time now get a "INTERRUPT EXCEPTION NOT HANDLED" with the following mem dump see attached file

Any help most appreciated

Thank you

 

New BsoD can some please analyze and get back to me how to fix or resolve this please

Thank you

 

suspect the same thing from today's Geforce win10 release.. a friends notebook caught in an endless reboot loop, couldn't access his dual boot menu, or anything. got him to force his system into recovery mode by pulling his battery a couple times during start up until i could service it properly in the morning. doing so he was able to boot back into win8 (startup repair didn't work for him)

i tried installing the geforce update on several computers at work today. failed in mid-installation each time. his acer laptop by far got the worst of it.
