installation of win 10 causing problems
I have a hp laptop (model 15 n022sa) and ive been trying to upgrade to windows 10 from 8.1 when i get to the first restart it boots back into windows 8.1 and says installation has failed.
I tried doing a fresh install from a dvd by changing the bios to boot into it on startup. Upon restart it seemed to not work again as i got an error message saying
"The computer restarted unexpectedly or encountered and unexpected error. Windows installation cannot proceed. To install Windows, click "OK" to restart the computer, and the restart installation."
After putting the boot order back to its original state i managed to boot into the os and this time it was windows 10.
But unfortunately it would not let me use my product key which i obtained via a free tool which looks it up in the bios. The details of the error says the code is blocked.
Also the updates of windows 10 wont install. They install and restart the pc and then it says it needs to undo them when configuring them.
I thought maybe resetting the os would help but it wont work and trying to do another fresh install greets me with the failed to install error after the first restart.
As a fairly competent pc user i can normally fix things but this is baffling and i think i may have dug myself a bit of a hole. Ive been at this for some time now and im a bit stumped. Please help
