Parrot OS

I was going to format with Parrot OS installed on my computer, I don’t know how it happened, the files of arch linux are left on the hard disk and I cannot open the computer normally. Parrot OS does not appear on the screen, although I have not installed yet, the incorrect installation screen of arch linux appears

You installed Arch Linux now? I wonder why Parrot doesn’t show up when you haven’t installed it yet?
