Hi Jungian, if I understand you well you have slided your taskbar. You just have to click and drag the start menu. You left click and hold anywhere on the taskbar and slide it where you want it.
If it doesn't work your taskbar is probably locked, you can right click the taskbar and uncheck "Lock taskbar"
