Change the MAC to 0000.0000.0001 on the switch you want to be root?
Change the switch priority on all the other switches to be higher than the
switch that you want to be root.

The bridge with the lowest Bridge ID wins.

*Select a root bridge.* The *root bridge* of the spanning tree is the bridge
with the smallest (lowest) bridge ID. Each bridge has a unique identifier
(ID) and a configurable priority number; the bridge ID contains both
numbers. To compare two bridge IDs, the priority is compared first. If two
bridges have equal priority, then the MAC addresses are compared. For
example, if switches A (MAC=0200.0000.1111) and B (MAC=0200.0000.2222) both
have a priority of 10, then switch A will be selected as the root bridge.
