I wish put another Debian, and with its command line.

Hi again.
My the wish is to have littlest OS, for more clear view on it. 
If I was not afraid wipe out MBR, I shall have made a very small partition and 
was reinstalling the OS from the flash drive in case of errors many times.
Many thanks for consultations, now I long shall not bother to you, (beginning 
work will be a dark forest for me).
Thank.
