Resize partition with GParted
How to install Windows 7 after Ubuntu and dual boot?
How should I create a partition in GParted so I can install Windows Vista/8 on it?
I would really like to put Windows alone or Dual-Boot (I would be so grateful for Dual-Boot since I love Ubuntu , But I need Windows at the same time!)
Here is the explanation , I have a 220 GB Hard Drive on , I want to resize it to 100 GB , Then the rest as a new partition , How do I do that? LiveUSB? GParted?
