One day, I started the computer and the loading was very long so I decided to turn it of and back on. Then, during the loading, a blue page (not a blue screen) appeared and told me that there was a problem with Windows. I chose to reboot the computer and the infinite loop got back. I manualy reboot the computer once again and the blue page (still not a BSOD) came back. This time, I chose to reinstall windows. It took a bit of time but in the middle of the process, it told me that there is an error and the windows reinstalling was cancel. It bring me back at the blue page (not the BSOD) and I chose to continue to Windows. Suddenly, a blue screen appeared. It was wrote: Unmountable boot volume or something like that. I went on forums and it was saying that I need to download Windows 10 into a CD or a Flash Drive. So, I downloaded Windows 10, install it in the key with a tool made by Microsoft, put the flash drive in the computer and reboot it. It told me which perephical to use, so I chose the USB key. Next, it probably started to install it and a new blue screen appeared. This time it was wrote: NTFS FILE SYSTEM I think. What do I need to do?
My computer is a Asus Sonicmaster, i5, 8GB of RAM, Intel Integrated Graphics and it is approximatly 3 years.
I really don't want to loose my data. But if it's the only choice, it's alright.
Help me please.
