I tried to install windows 10 through windows update and it failed so I thought it was a problem once but it happened 7 times (always once it went to install), so then I used Windows Media Creation tool that is used for making a Bootable USB device but can also upgrade devices.
Windows Media Creation tool downloaded windows and I accepted the terms and conditions then when it went to install it said it failed.
I now don't know what to do, I have tried 8 times and I have given up.
Also I have a legitimate version of Windows 8.1 that was pre-installed with my laptop (http://support.hp.com/gb-en/product/HP-Pavilion-15-Notebook-PC-series/7234915/model/7547532/).
Help would be greatly appreciated!!! Thanks in advance!!!
