-So, let's look for any gparted-livecd ISO file in the current directory.
-I found gparted-livecd-0.3.4-8.iso.
It will be mounted to prepare the usb stick
Currently creating directory and mounting ISO...
(for i in gparted-livecd*.iso; do mkdir /tmp/gparted | mount -o loop /tmp/gparted;done)
mount: -o loop: option not supported
-Where is mounted your usb stick, please ?
It can be something like /mnt/usb or /media/disk1.
-n -Type the full path, please :
/dev/disk2s1/
It seems you're wrong :
either nothing is mounted on /dev/disk2s1/,
either at least two devices are mounted on it !
-Please run the script again after you identify the right path,
and correct the problem.
