Just boot ur console with the mod on, and place the slayer disc on the dvd drive before give u an error msg
So the slayer would load before an error msg if u have a propper bios with clock loop fixed, if slayer loads
Rebuild all ur original hd using slayer 2.6 to have all ur original ms dash fine
Once i've heard that locking/unlocking the hd solve that problem
Update ur bios (not necessary but would be good if u update it to xcuter 4981/4983
I hope that this solve ur problem
