What can I say,
Try with other installation media, or format the drive if you didn't. Sometimes even trying to install of pendrive on old mobo is impossible. Try making the installer with RUFUS (configured as MBR+BIOS - not UEFI - as it may also cause issues on old computers), it may help.
Have you tried going trough lua.org manual Lua 5.3 Reference Manual - contents ? It pretty much covers most of the stuff.
As for programming in general I am willing to help. I think I wrote enough code to be of use.
Anyone here also Git gut, on Github/alternatives?
