At best, my computer hangs when prompting for a password. I think this is related to the 4.4.14 kernel but have not confirmed this.

These instructions are a lot easier than they seem, and a smart and patient beginner will be able to follow them!

  • These notes were made from instructions from Slackware "current", as of 2016-11-05, and have been tested on Slackware 14.2, and 14.2 32bit.
  • These notes were made on an everyday system with one hard drive which I completely formatted for this purpose.

    • If you are a new user, it is strongly recommended that you remove all hard drive's your using and do this on a spare unused/empty drive.
