Hi, I have a HP Pavillion 15-ab031ax which previously on Windows 8.1. It was my friend's laptop and he asked me to upgrade it to Windows 10. So, I did what I usually did by creating a bootable usb disk and then install Windows 10. At first I was having a problem with "Couldn't create new partition bla bla bla" problem and I solved it by following instructions (the diskpart thing) from some very helpful videos on Youtube. After solving the problem I tried installing Windows 10 again only to see it fail again and again. It keep restarting the laptop when it was loading at "getting files ready for installation". It can only reached 70-80% before restarting the laptop and starting over the windows installation. Can someone please explain what is the problem and the solution for it? Thank you
