Using a computer today can be very satisfying, you can do a lot of things and you can browse the most interesting, useful, and fun websites, as well as being an indispensable work tool in many offices and for many professionals. If we find ourselves in the situation to turn on the Windows computer and it stops with an error and does not start, we risk not being able to work anymore and being stuck even for hours!
If Windows 10 doesn’t start, the first thought goes to the files stored on your computer, all your vacation photos, work or school documents, term papers, cell phone backups, and so on.
In this guide, we will show you in detail how to save important data and files of your computer to prevent them from being inexorably deleted. After saving your personal files we will show you how to reset your computer to restart it and go back to work or to have fun.

How to save files and restore Windows 10

Before following any recovery procedure for Windows, it is advisable to save our personal files, using an emergency operating system that we can start directly from a USB key or CD disk, according to our needs.
We anticipate that to do everything correctly you need to have two on hand empty USB sticks at least 8GB (for the operating systems we will use) and a portable USB hard drive (on which to save our personal data).

How to recover personal files

To recover our personal files we will have to download a GNU / Linux distribution and insert it into a USB stick of at least 8 GB so that it can be used as an emergency operating system to access the hard disk of the non-functioning PC; obviously, in order to create the emergency operating system, we need another working PC, on which we will create the boot drive.
To do this, we suggest you download the Ubuntu distribution and the UNetbootin tool, both of which are available for free.

At the end of the downloads, we insert the empty USB key chosen for the purpose in one of the homonymous ports of the computer (the one used at this moment, ie working) then open UNetbootin, select the item Disc image, press on the three dots on the right side, select the Ubuntu ISO downloaded previously, select the USB key in the field Unit then press OK to start the procedure.
At the end of the process, we remove the USB key from the working PC and insert it into the computer that is making a fuss and then start it changing the boot order, so as to be able to access the operating system stored on the key.
Ubuntu

Let’s make sure to start Ubuntu Live by selecting Try Ubuntu and, once inside the operating system, connect an external hard drive to another USB port then open the file manager (press on Home or on the File app), press on the Windows disk icon from which to save the data (on the side left), we access the Windows personal files folder (usually the path is C: Users, in which to select the folder with our username).

Windows 10 compared to its predecessors offers numerous bootable recovery tools without having to format everything, so you can get back to work as quickly as possible.

Now, all we have to do is get comfortable and wait: the tool will download the updated Windows 10 and create the key by itself, without any other intervention by the user. As soon as the USB key is ready, remove it from this PC, insert it in to the non-working computer and start it, making sure to change the boot order.
The classic Windows 10 installation procedure will start, in which we will have to select the item Personalized, select all the partitions on the non-working PC disk and press the button Delete, so you can immediately use the unallocated space for a fresh installation of Windows 10.
