I can't resize the partition boot, I looked on many tuts but none worked. I don't know why. I want to resize sda5 and take 1gb from it then give the 1gb to /Boot

enter image description here

who I typed sudo fdisk -l in terminal:

Why are you want to resize /boot/ partition ? –  Sepahrad Salour Apr 20 '13 at 19:03
    
what version of ubuntu/gparted? From what I understand LVM support is limited in GParted and only a recent addition, but I would make sure I had the latest version of GParted –  Logman Apr 21 '13 at 0:58
