Hello 1032,
Welcome to the forum and Linux Lite
Why did you need to reinstall, eg; which issues did occur, after which changes made etc ?
Have you added any commands in to the "terminal" (how you called DOS like equivalent), on the current install of LL ?
If so please list any that you can remember at this time, for each one add a details of why you added it/ what you wanted to achieve with it.
Or is current install clean no changes made, or tried ?
Also add a list here of all the simple task things you want to do.
It should be each topic goes in its own thread for that subject to attract more responses from the community.
