You must be confused. There is no such thing as command mode on a PC. What you are probably referring to is the “command prompt”. And, again, your confusion is obvious, you might be referring to the repair console when stating that a recovery CD boots to a command prompt.
I saw your smart azz post about me, you should really make sure your azz can cash your mouth’s checks before you write them.
My recovery cd boots up to a command prompt. That is command mode, as you will find out if you read your windows documentation.
