'''boot2''' is the [[Wii]]'s third-stage bootloader. It is responsible for loading the [[System Menu]] [[TMD]] and loading the appropriate [[IOS]] under normal circumstances, although it can also load [[MIOS]] if it detects a flag set by [[BC]], and it can simply shut down if it detects a flag set by MIOS.

There is also a path that loads BC, although it appears unused.

There are two copies of boot2 housed in [[Hardware/NAND|NAND]] blocks 1-7 in case of failure, loaded by [[boot1]]. Additionally, a copy of boot2 exists as title 1-1 in the NAND filesystem.
