Manage and fix the startup manager.
Grub is one most used boot loaders by users that have more than one
operating system installed on our computer, but it doesn't lack its errors and thus needs its maintenance.
Super Grub Disk is a disk that once launched
allows to install Grub, its modification or to repair it, in the case that something isn't working properly. Thus, it will be a lot easier to install new operating sytems.
A clear example of the utility that can be given to
Super Grub Disk is that when we have Linux on our computer, we install Windows, but since the Microsoft operating system completely overwrites the boot loading system, we won't have access to
Linux. For this kind of problem, having
Super Grub Disk handy can really help us a lot, because it can
allow us to reinstall Grub taking into account all the systems we have installed.
What's more,
it allows to solve problems in the Windows boot loader or to select from where we want to boot, allowing that a partition that couldn't be identified correct to work properly, for example.
