Get rid of that CLS, and look what the startup screen says.
At least you can read then if there is an error message.

I finally found a cd version of Guilty in the web but ......

Isn't the CD version the sequel, from 1995?
If it's a bad ripped ISO nothing will help you.
You can find the floppy version also on the net,-(the first one 1993)-, that one works flawless in dosbox.

It also would help if you stated WHAT OS you're on, it is possible to fine tune the CD mount, but that's OS depending.(IOCTL-XP and ASPI-W98, ...usecd ...)

Details ...details ....
Next question:When you look in Windows at your CD, does its shows a label? (CD name)....
