Thankfully, all is not lost because there is an excellent little tool called Plop Boot Manager which can do the impossible and allow you to boot the computer from USB even if the BIOS does not support it. However, what if you encounter an old computer that doesn’t support booting from USB? It depends entirely on the computer’s BIOS as to whether USB booting is supported and some manufacturers may have provided a BIOS update to enable it. Installing Windows by running the setup files from a USB drive is also popular because it can be a good bit quicker than installing from a CD/DVD drive, even Windows 8 setup files can be downloaded and copied straight onto USB these days. Having them on USB is easier and quicker than burning discs every time. Being able to boot your computer from USB flash drive is an advantage because there are so many tools around that can be used to install or repair Windows such as Antivirus discs, and repair CD’s.


Although it’s not such a major problem with computers manufactured in more recent years, if you have a slightly older computer, something it might not be able to do is boot up directly from a USB device.
