EasyUEFI boots your computer from the current Windows OS using an untouched (and previously saved) boot menu that's typically in the form of a series of Windows OS images stored on your hard drive. With the help of this boot menu, your computer will automatically load all necessary drivers and other settings required by the Windows Operating System to run. Based on the kind of Windows operating system you're using, EasyUEFi boots your computer from different files & settings. For example, Windows Vista requires boot entries from the CD loader during the boot process; hence, it needs to be enabled using the corresponding EasyUEFi component. On the other hand, older Windows systems use a series of shared files and settings that are loaded during the boot process by your computer's operating system, and which are then subsequently unloaded as your computer restarts.
The above mentioned characteristics are all based on Microsoft's proprietary drivers that have been built into the Windows OS. With the help of this driver, your Windows-based computer will now load the necessary driver and other configuration values from the EasyUEFi image file. As the software is written into an image file, it can then be read by the Windows operating system just like any other normal file. Therefore, you will never see an EasyUEFi bootable USB flash reader unless you've modified your computer's boot configuration. Furthermore, this driver also offers various other great benefits such as making sure that no red-screen errors appear even when your computer has encountered numerous hardware issues and achieving better compatibility with various computer brands and hardware accessories.
