I downloaded parabola-systemd-lxde-dual-complete-2018.06.04.iso and now I got an installation error.
I must say that the USB stick I'm currently using live system of was not prepared with dd (bios refures to boot from dd version), but UNetbootin, so it may be the one causing the problem. In fact, it did cause a problem: I named the only partition "FORPARABOLA" right before using UNetbootin, a program to make bootable usb sticks, and the Live system failed to boot at first, because it apparently sought for disk label "PARA_201806" and couldn't find and mount it. I solved it by creating a symlink (Live system wanted a symlink, whose path I don't remember) to and then mounting /dev/sdb1 on "/dev/parabolaiso/bootmnt".


That's what graphical installer says:
