OK So I tried a different laptop and this time everything went well. I ran into that error Collector found, but like he said, it's fixable by changing cpu options on DOSBox.
I have no idea why since I did nothing different. Well thanks for the advice guys.
As for Qbix's question, actually my path is the following: D:\Windows 3.1(This is the folder where I had all my Win3.1 files to start installation)\WINDOWS\"Insert various files folders like SB16 etc. here"
So Is it a path problem?
I did insert a few specific path instructions on dosbox.conf's auto section like the VOGONS guide Collector pointed me to yesterday, but it doesn't seem to do anything.
