I have installed Ubuntu 3 times and screwed it up 3 times trying to point the OS to my pre-existing separate home partition (sda3) named /home. It is on the same drive as the Ubuntu install (sda1).

  1. I know the UUID for the home partition.
  2. I know fstab needs that new UUID.
  3. UBUNTU does not like me trying to change the name of the new /home directory or removing it: resource busy error.
  4. So I know I need to rename the new home to somethimg else (home_OLD say) and delete it later as I see fit.
  5. Then make a new home directory (mkdir).
  6. Either my sequence of events is wrong or something because Ubuntu is freezing up when I restart it. Is there a definitive link that explains exactly how to redirect home to another partition? I want to get this done before I start reinstalling apps so any relevant information is placed in the existing home partition and not in the new home directory. So I am hoping to get a definitive answer or link to guide me through this process. thanks....

When you reinstall, do not allow the installer to automatically configure the disk. On the partitioning screen, pick "custom/something else" and manually select your /home partition. Pick Edit, choose "do not format" and set the mountpoint to /home. That is all.

From your partial and incomplete description, you are not doing this, but trying to do it later. That is the wrong way.

Decided to to install OS with home residing inside same partition as OS. KISS - keep it simple stupid. I do not need any unnecesssary headaches with my limited skillset.
