Hash problem

Hi so my freind gave me a copy of the program on an sd card. I tried installing on virtual box through a tutorial. During system installation it would error. I did some reasearch and figured out that it might be a hash problem. How do i fix this thank you

Os parrot security 4.1

Oracle Virtual box standard install

Configured to multiboot with other systems? no

Cannot install system (i think its hash how do i fix)

Check your ISO hash:

If it is differ, then download the iso (and check the hash again)
