I installed Parrot Security os-4.8 twice on virtualbox on my MacBook Air (2015), and after successful installation with no errors (both times), after rebooting virtualbox, again I get the option to use it as live or install with other options that appears as if the OS is not installed. I checked the vdi and it appears to be of 6gb in size(I think the OS is still there).
Any suggestions? Thanks in advance.(sorry for bad English)
