G'day PCTECHSCB, and Welcome to linux.org
Give us some detail
What are trying to install this on.....specs....make, model, etc
have you used linux before...or is this a "first time" for you
Have you tried to install any other distro...eg linux mint ?
Are you dual booting...if so with which other distro....?
What is the eventual outcome you are hoping for ?
@poorguy is right... this distro is now dead (at least for now). Wherever you downloaded Black Lab, I would not now trust it. Even if you got it to install, it would not update and would be risky to use online.Best I can tell is they are no more.
