So I booted Parrot OS from an external drive (SanDisk 3.2Gen1) and I gave it 32GB of persistence (I don't know if it really does anything to help). Now I am trying to partition the drive. Everything goes well untill i try to install it to the drive. It just pops this error and I don't know what to do next. Error image
I have tried to do it with the GParted program but that doesn't work either.
Looks like you are trying to partition the drive the live system runs on? If so, try booting from another drive than the one you'd like to partition.
