That's strange, it's completely different to mine...
From the command line can you type:
This should download and extract the noobs files again... then
Finally power off the Slice and power it back on again
Should come up with the selection menu, don't install anything just ctrl-alt-f2 again and repeat the parted /dev/mmcblk0 and take a picture
Next Ctrl-Alt-F1 to get back to the menu and select Slice (stable) and "Install" (ignoring the warning messages)
If that doesn't work can you return to the command line and repeat the parted commands again...
