Creating a batch to ask a question

[chon_]

I use this code to ask if the user wants to install NIS or NSW, it works ok with the cmd method, but when using the windowsupdate and the inf method, it won't work, hmmmm.... nope, the keyboard it's what isn't working, i can't type anything within the cmd window. it won't let me input my option.

Anoyone know why is this happening?
