But more often in a computer system is only use an operating system more and more users choose to install two or more operating systems on your computer for different purposes by each. As the current computer architecture is developed to boot an operating system while we install a software that allows us to choose which operating system to boot we want every time we turn the team.
In this article we will discuss the main options we have in our system to configure dual boot to choose the system that we want to load when you boot your computer.
Windows typically install one bootloaders on our system, however, only when we have an operating system installed this manager does not appear at startup automatically loading the system.
If we need to install multiple Windows operating systems (e.g. Windows 7 and Windows 8) we can use perfectly one of the Windows Boot Manager to choose the operating system you want to boot by default at system startup. Installation and configuration is very simple, all you have to do is make sure first install the oldest operating system (Windows 7 in this case) and then the most recent (Windows 8) so that there is full compatibility between them.
When you install Windows 8 installation process will detect a previous partition with Windows 7 and will automatically add an entry to the boot loader so that the boot can choose where we want to load and use.
Grub and Lilo, the Linux bootloaders
Although the boot manager works with other Microsoft operating systems it has been designed to work with other Windows, but could fail when adding a Linux system or a Hackintosh. Linux also installed one of their own bootloaders that are much more complete and compatible to the Windows Boot Manager.
Several bootloaders that are installed in our distribution, however, one of the most powerful is Grub. Grub will allow us to easily select the operating system you want to boot into a simple list Compatible with all types of systems (Windows, Linux, Hackintosh, etc).
To install and configure Grub first thing to do is install all operating systems want to have in their respective partitions. Once installed the latest systems we will install our Linux (Ubuntu specifically) to that during the installation process Grub is installed.
Grub will automatically detect all operating systems installed on all partitions on the computer and add an entry for each of them without us having to do anything. If we remove a system or install a new one we just start our Linux and type “sudo update-grub” to update the configuration with the new systems.
Grub, apart from being a very complete and fully functional tool is also fully customizable and can obtain similar to the following appearances.
BootIt another separate boot manager
BootIt is a manager separate boot the operating system that will allow us to set up a dual boot operating systems you have installed. This application will allow us to configure the disk (partition, computer, format, etc.) and create a complete bootloader much more complete than the above options (we can, for example, protect an operating system with a password to prevent access to it or use a own format files to create more than 4 primary partitions on a disk).
BootIt is a complete manager and administrator must for the most advanced and demanding users disks, however, is a paid application that may not be available to some users and against powerful free alternatives like Grub make investment not It’s worth it.
