Cisco Catalyst 3560G IOS installation

[calderonl.odari11]

Good Day,  

I have a 3560G catalyst switch I use for practice and by accident I deleted the IOS. Every time I console to it and then press enter I get this  XX▒▒X▒8▒▒X▒▒X. I was wondering if there is an option for me to buy the 15.0 IOS from cisco and then install it to my switch. Again this switch is with me at home to be used only for practice purposes and I want to install the 15.0 IOS from cisco. What is the procedure I need to follow?

if you have a contract and CCO id, you can download IOS and install it yourself.

make sure your console settings are correct, when you lost IOS, you get ROMMON >

check below baud rate settings

I don't have a contract and CCO id. How can create or get those?
