Toshiba SATELLITE L75D-A7283 Replacement Screen for Laptop LED HDplus Glossy

so i have today with me is toshiba's satellite l 75d dash a7283 laptop and i'm going to go over it to quickly review the good and bad thing about it the first thing that you will notice that it boots up with windows 8 into it it's not really great in the sense that not only it's it's uh does not allow me to go inside this computer easily but also because when i try to upgrade it to from 8 to 8.1 it will upgrade it and then it will try to reboot it and once it reboots it it says that it's not able to upgrade to 8.1 for some reason or i'm not sure just this laptop or other laptops are facing the same problem but basically the windows 8 or 8.1 for that matter it's something i don't like about it so what i did i installed something that they call a classic start you can search about it in the on the internet and once it does it once you click the home window windows button which is right he
