Back up your data

Before going to install Windows 10 from USB, I invite you first to backup the data currently present on the hard disk of the computer on which you intend to act.

In this way, you will be able to ensure access to your files even after the installation of Windows 10, which would otherwise be irrecoverable (unless you choose to update the current operating system instead of performing a clean installation or to split the PC hard disk into different partitions).

To back up, just use an external hard drive and transfer all your personal files on it, as I explained in detail in my guides dedicated to how to transfer files to external hard disk and how to backup data . If you do not yet have an external hard drive and would like to receive some advice regarding which product of this type to buy, I suggest you consult my buying guide .

Partition the disk

If you want to install Windows 10 without losing the data that is currently saved on the computer and you do not want (or cannot) use an external hard disk, you can consider partitioning the PC disk thus going to create a partition specifically intended for the new copy OS.

To give practical examples, you can create a partition intended only for the operating system and software and take advantage of the remaining disk space to store data or, again, you can evaluate the possibility of dividing the disk to have a partition with the old version Windows and the data currently on the computer and a new partition to host the new copy of the operating system, programs and other data.

To do this, you can use Disk Management , the utility included “standard” in all versions of Windows, which allows you to manage internal and external storage units: to find out more, follow the instructions in my guide on how to partition a hard drive . Alternatively, you can consider taking advantage of third-party software used for the purpose, such as the ones I mentioned in my review on partitioning programs .

Configure the BIOS

You can find all the details on how to proceed in my specific guide on how to enter the BIOS .
