Error 80070004-4000D while updating fro 7 Ultimate to 10 Pro

Hi,

while upgrading fro Windows 7 to Windows 10 Pro I get the error above (I tried several times).
Does anyone know how to solve this situation.

Thanks

I am fed up with this free upgrade - I've tried four different time over the last year to upgrade - The last one 8 hr later 99% loaded and I find the error 80070004-4000D
Windows should have researched this a year ago. No one has a good solution to this error. Believe me I've tried several. I am not going to waste another minute with is. This is a HP g60-533cl notebook running windows 7 just fine. My next pc will be an Apple.
