So, I don't know how to go on with my analysis of the load, since I can't determine the reaction forces. Can someone please help me? Thanks in advance!

This beam is what is known as a "propped cantilever". It is statically indeterminate.

You will have to write additional equations, knowing that the deflection = 0 at B and the deflection and slope of the beam at A are both equal to zero.

There seems to be a hinge between A and B. This makes it statically determinate. At the hinge, the bending moment would be zero, and this gives you the additional equation you need to solve the problem.
