I can't talk about all of Europe, but in Austria we have the Wirtschaftskammer ("chamber of commerce"), and they offer free consultation and workshops for people who want to start a business. Many universities/schools also have their own incubators. They can help you get started with everything you need to know. If you want to get in contact with investors, that's the way to do it here. And you'll meet a lot of like minded people. As for accounting etc, you usually don't do accounting yourself, you'll just pay an accountant to do it and they'll tell you everything you need to know. If you want to consider another degree, make sure to look at the community around the program. It's not a coincidence that a lot of startups are founded by the alumni of a few schools. If you don't know any startups founded by alumni of your university, maybe look for something else. In my mind, the biggest advantage of doing another degree is meeting potential cofounders.
