Udate to LINUX

#1
I have a TRIUMPH-LS s/n 298, operating on the Windows o/s. I would like to update to the LINUX o/s, but I cannot find instructions for doing this. I need help.

The migration took place, but I lost all of my files, and all of my set ups. I do not know how to create the set ups. I lost my RTN, which is Mississippi Department of Transportation. WiFi is on, I think. I know this can all be fixed. Loosing all my jobs and all of my data is a problem.
