Fortunately, Parrot OS uses the same type of Calamares installer like PureOS. Also, there are try/install, ram, memory test, troubleshoot, live, and so further boot modes after applying USB boot; however, try/install is recommended and worked perfectly without encryption enabled if and only if PureOS partitions are copied exactly via manual partition.
