Linux is one of the most secure operating systems in the world. But, Linux is often installed in dual-boot systems. As opposed to emulating, this allows you to run Linux on your real hardware. The main advantage of having a dual boot system is that you can always reboot into Windows if you need to run Windows software or play PC games. Dual boot is usually used for various purposes, such as learning about the operating system, or for a job where the usage of an alternative operating system is more optimal. Dual-booting also strengthens the security of your PC. When one OS has a problem, you can use the second OS to fix the problem properly. For example, when the Windows OS is infected with a virus, the second OS, Linux can clean and backup data affected by the virus. This is because the Windows virus cannot run on Linux.
To make a dual-boot system you need a bootable USB maker software to prepare the installation media. For this task, you can use a software like Rufus. Rufus is one of the most famous software available for this purpose. It is an open-source software and therefore doesn't cost a penny. You can download this software from the Rufus download page. There are several methods to make a dual boot system with Windows and Ubuntu. Ubuntu itself already provides dual boot options on the installation media. But, in order to avoid issues, it’s better to install both operating systems separately and unrelated.
By doing this, we separate the Linux boot manager from the Windows boot manager. As a result of this, when we reinstall Windows, the Linux boot manager does not go away with the new Windows boot manager. By separating the two, we don't need to worry about Ubuntu when Windows has a problem, and vice versa.
If you prefer the old way of using CDs and DVDs, just burn the ISO of Linux file to a DVD using a disk burner software and you are good to go. But for those of you who choose to use a USB flash drive, you need to make a bootable Ubuntu USB flash drive first. As I mentioned earlier, Rufus is the perfect software for this. Simply download Rufus, install it on your PC and locate the ISO file by using Rufus. Within a few minutes, you will have a bootable USB flash drive.
After creating your bootable Ubuntu USB flash drive, just plug it in your PC and boot from the USB flash drive to install your secondary operating system. If it doesn’t boot, you may have to adjust your boot order via BIOS. When installing Linux, make sure to install it on a completely different partition. When compared to other methods, this method may seem long, but in this way, you can minimize problems. Even if there is a problem in the boot-loader for some reason, then fixing it is very easy because you just need to enter the boot entry again via EasyBCD in Windows. That's the main advantage if the Windows and Ubuntu boot-loaders are separated in different partitions.
