And now it suddenly does work and finished the windows 10 update. I think I will never fully understand computers...
Thank you for joining the Intel® NUC Community. I am sorry to hear you are having issues with this matter.
Let me know how it goes.
Yes, I'm sorry I forgot to reply. I did the BIOS recovery and everything worked fine.
Since then I did something that completely messed up my computer, but that was on microsoft's part.
The only assistence I now require is merely psychological, but I don't expect you to help me with that. ;)
Thanks for the advice.
