I am trying to delete my linux-swap partition /dev/sda5 and allocate the free space to /dev/sda6.
But when i try to delete sda5 GParted gives an error "You have to umount sda6". But i can not umount sda6. I gives me the error "umount: /: target is busy" If i reduce the size of sda5 i can not allocate the unallocated space to sda6.
Can anyone give me some advice on how to do this the right way?
I have a multi-boot system with windows and Linux. (Grub2)
