Window 10 up grade failed 2 times

I have an H/P Pavilion g6 lap top. Tried to upgrade to Window 10 twice today. It seems to down load fine, and starts the install phase, when it gets to the black screen where it say it will restart many times, it starts copying files. It gets to 85/87% it shuts the power off to the computer. When you push the power button, it starts up, saying it is restoring previous version of Windows (8.1). Gives a dialog block with Red Shield and an (X) saying some updates were not installed, Error found C1900101-2004,

Can you help with this problem.

Re: Window 10 up grade failed 2 times

I got the same thing 4 times. I suspect my issue is the fact its dual booted 8.1 and 10. I've haven't had the time to remove the 8.1 partition so I suffer in silence. Are you dual booted?
