regarding parrot security 5.0 operating system.

[manohar27001]

after the installation of parrot security 5.0 operating system in my virtual box, you know it asks for the restart and doing so, it again asking to install the os and it keep on repeating.....

You probably need to manually "eject" the live image in your VM settings in VirtualBox.

Did you verify the integrity of the .iso before you proceeded with the install?

SlowCoder likely has it correct.

Devices > Optical Devices > untick the box for the installation media

You can also use F12 during the VM's boot process to pick which device to boot to.
