On the root of you're SD Card there should be a folder called BootMii and a config file '"Open it with Word Pad" it should look like this..
# BootMii config file
# Video mode, possible settings:
# NTSC, PAL50, PAL60, PROGRESSIVE
VIDEO=NTSC
# Autoboot, possible settings:
# SYSMENU, HBC
#AUTOBOOT=SYSMENU
# Autoboot delay, in seconds:
# Default is 5
#BOOTDELAY=5
is that there?
Are you sure it installed to Boot2 some Wiis cant do that, was there any errors?
I got to crash out soon so I might have to help ya tomorrow just don't go jumping the gun..!
Lets get BootMii working before doing anything els..
