Sometimes computers crash because of the errors in the OS or errors the hardware itself. However, most of the errors are software system errors. It’s very easy to diagnose software errors and fix them. Today, I am going to show you how to reinstall your OS in order to fix system errors. I am going to install the OS by creating a bootable USB stick. I am going to use Rufus to create the bootable USB. With this program, you can easily install your desired operating system on your computer without the need for a CDs and DVDs. This is especially useful for devices such as ultrabooks, tablets and netbooks that comes without a CD and DVD drive. Since the installation from USB drive is faster than CD and DVD drives, operating system installation will take less time than usual.
So the process I am about to show you is very simple. There is nothing complicated about booting from a USB flash drive. All you have to do is follow the simple instructions carefully and everything will work. Rufus is a portable software and therefore you don’t have to install it to use. You can simply download it and run it right away. When you run Rufus after downloading it, a very simple interface will appear. On that interface, you will see an area for the ISO selection and USB drive selection. Even though Rufus has an area for USB selection, you don’t have to manually select it since Rufus has the ability to detect the USB drives that are plugged in to your computer. Once it is detected by the software, it will show up on that field.
After that, you can proceed to the next step, which is ISO selection. Just locate the ISO file by clicking on the “Browse” button and now you are all set. Click on “Start” and it will take few minutes to complete. After that, you can pull out the USB and boot your PC from it.
If you don’t know how to enter your BIOS, then let's understand how to enter the BIOS. As you know, the BIOS is located on a chip on the motherboard. There are many computer brands in the world and therefore, there is no single key to be entered. The most commonly used keys are F2 , F8 or F1. If that also doesn’t work, you may have to contact your computer manufacturer. You can also do a quick search like this this and I’m sure that you will be able to find this easily.
