Of course, a simple solution may be to use a live usb. When the live usb is booted, gparted can be installed onto it. The gparted pgm can then be used to make partition changes to the unmounted server. The live usb will support gui programs.

Finally!!! Thanks alot man I finally got it, I didn't know the End how to be exact.. Got it though thanks dude problem solved.

I don't understand why is that? Does the USB have a gpu or is the graphics produced through number instructions?

According to @DavidMcCann your motherboard has rudimentary graphics capability. I don't see where you've mentioned what your system is so I don't know where he gets that, but if it's true you could boot from something like SystemRescueCd and let it start up its own X server. Performance wouldn't be great, but entirely adequate for a tool like gparted.

You need a computer with a graphics card which can access another computer without a graphics card. If you don't have this setup then it won't work, as you can guess.
The live USB can be used to remotely access the computer without a graphics card so that gui programs can be used to manipulate that computer.

Of course it's important to know how to do sums in our head. But if a simple calculator can do this more quickly, then we don't need to do sums in our head.
Programming is not about remembering instructions. It's about finding the most simplest way of doing something.

Ahh i get it, good to know in case I need to do something like that, thanks again fellas
