Etcher or dd is suggested. Install errors may occur using anything else.

I use PowerISO to burn the dvd, when its on live mode it works well this show that theres a problem somewher

[sadiq (Malian)]

take a look at this image, i only need to use parrotOS as my default OS, is there any way to install it successfully?

here are my Gparted from the live mode

First off, I would suggest reburning the DVD (or USB stick) using (dd inside live mode if you have enough ram). Some burners do not write the ISO properly. Only Etcher or dd are suggested in the Parrot Docs:

https://docs.parrotlinux.org/getting-started/create-boot-device/

Many report success using the GTK installer at boot.

Try installing this way instead of booting live.

And of course, let us know how it goes!
