How to install Windows 10 from a bootable USB stick

Do you need to install or reinstall Windows? The start of Windows 10 (e Windows 7) from a USB key is immediate. Within minutes, you can have a new version of Windows installed on your PC, notebook or media center.





Here's everything you need to know about installing a fresh copy of Windows 10 from a bootable USB stick.

Why start a Windows installation from USB?

If your PC does not have an optical drive (and more and more do not have one), or if you have run out of DVDs and don't want to buy more, a bootable USB stick remains the best solution.

It is very light, not cluttered, and is compatible with any desktop or laptop PC. While many PCs do not have a DVD player, they all have at least one USB port.

Installation from a USB port is even faster. A USB reader can be made bootable faster than an optical reader; it also installs the operating system faster.

To install Windows 7 or Windows 10 from a USB stick, you need a device with at least 8 Gb of disk space. Before proceeding make sure that the key has been formatted.

Make sure the USB stick supports UEFI booting

Before downloading a bootable Windows image it is important to know the difference between UEFI and BIOS.

Older PCs were based on the BIOS to start the operating system and to manage the data that passed between the operating system and the devices. In the last decade the UEFI (Unified Extensible Firmware Interface) replaced the BIOS, adding support for devices of the past. UEFI can help diagnose and repair your PC without the need for additional software.



Fortunately, the most common methods of installing Windows 10 from a bootable USB device support both UEFI hardware and hardware that refers to the old BIOS.

So, whichever option you choose should work for the hardware you have available.

If you really don't like Windows 10 and you have a valid license for Windows 7 you can also install this operating system from a bootable USB stick.
