BootLine

More often than not, after you have installed your operating system on the desired partition and placed all your personal data there, it is recommended to create an image of the OS, which serves as an exact backup of all the system files, drives and programs.
BootLine is a lightweight application that enables you to create bootable images of various operating systems on USB flash drives.

Comes with a standard and browser interface

It is necessary to mention that you can download the portable version of the application or you can use it directly from the browser, provided that you have Internet Explorer 9 or later.
The standard app comes wrapped in a modern and sleek interface that enables you to select the desired USB drive, operating system and ISO files you want to boot whenever the situation calls. You should know that you can add up to 10 loaders and remove them as necessary from here.
The browser interface is a bit more chunky and rugged, but it comes with a how-to guide, just in case you are not familiar with how this process works. The advantage of creating a bootable USB flash drive using this UI comes from the fact that you do not have to worry about downloading and launching any program you know nothing about.

Works with most operating systems

As previously mentioned, the program enables you to burn an image of any of the operating systems you are currently using. In addition to Windows versions 7 to 10, 32 and 64-bits, the app can help you create rescue disks and tools for creating partitions on your hard drive.
On the other hand, you should keep in mind that it does not allow you to create an ISO file, so you can use another third-party software solution for this purpose.

A good tool that enables you to build bootable flash drives quickly

All in all, BootLine is an efficient utility that enables you to burn loaders to flash drives without formatting in most cases, so you can restore your OS in case if it crashes.
