With the advent of netbook laptops and later on ultrabook laptops, there has been the need and not just an alternative, to installing operating system software without the means of a digital versatile disk (DVD) or any related disc for that matter. For some reason other than sheer marketing, netbook and ultrabook laptops came without an optic drive in it which poses a problem whenever the need to reformat the operating system arise. This does not just apply only to ultrabook laptops and netbook laptops. It works even on notebooks and desktops so long as either has a working USB port in it. This brief tutorial is intended for Windows 7, 8 and 8.1 operating systems and will teach you on how to reformat / format your computer with or without an operating system on it, or better yet, install an altogether upgraded version of the mentioned operating systems if existing older version of the operating system exists given the proper hardware settings.
Tools needed:Windows 7 / 8 / 8.1
Windows 8.1 onlyDifference between a 32-bit and 64-bit Operating System:

Issues encountered when installing / reformatting a computer using a USB bootable installer:
Q: How come the installer won't boot even after the USB bootable installer is inserted and the computer rebooted?
A: Check your computer's BIOS setting and set any USB device at the top (initial) order of boot. It must be set as the first among other hardware components to boot after every start of the computer otherwise the system will skip it. Also, refer to this
Q: Any other issues?
A: Aside from what's mentioned above, under normal circumstances (no hardware issues, etc.), you won't encounter any problem with the process.
