cd image for MT

and is there any prog for make it?

Donwload the CD image from the download site, the current 2.9.1 image for example is at http://www.mikrotik.com/download/MTcdimage_v2.9.1.zip.
Unzip it (using WinZip, for example), and burn the unzipped ISO image with your favorite CD burning software (Nero or whatever).

Then boot from that CD… Should be pretty easy.

here is a nice guide:
