how to control grub using GUI tool

grub-choose-default

I like to test more than one operating system at the same time so that i can give a better support to the users. Being an IT person and if you have more than 100 users it would be difficult to spare any time even to waste on booting the system more than two three times in a day and then wait for it to come to the boot menu and select the appropriate operating system to boot into and test the desired things. Isn’t it annoying when you want to reboot from Linux into Windows or vice-versa, and you have to wait for the machine to shut down, the BIOS to initialize just so that you can now select the OS that you want to boot into? grub-choose-default gives you a GUI that you can use to easily select the next default for grub and you can go and grab a snack while your computer reboots without having to wait for anything.  It’s a very simple program that just reads your grub menu entries and then lets you click on the one you want to be the next default.
