The 30A fuse does three things.
1. Carries charging current from the regulator/rectifier
2. Provides power to the bike via the main relay and then the three other fuses.
3. Provides power to the ignition switch to activate the main relay and ignition control unit.
If it's blown (and melted) then it's either had too much current through it or it's had corroded terminals causing it to heat up from a poor connection.
If none of the three smaller fuses are blown then the fault is not after them. That means it's somewhere between the 30a fuse and ignition control unit/main relay via the ignition switch, or between the fuse and the main relay supply feed, or between the fuse and the regulator/rectifier.
You've changed the fuse and nothing is working? So either it's a wiring fault and you're open circuit/blown relay or there's no power from the battery.
If it's no power from the battery, is it boiled dry? If it is, suspect the regulator/rectifier which would be the first place I'd look.
If there IS power from the battery, there should be power to the fuse, and therefore the switch.
I would start by getting a multimeter and checking the battery power then tracing it along from battery to 30a fuse to relay. If you don't have a meter then start by unplugging stuff. Ignition switch, main relay, regulator/rectifier. Odds-on that one of the plugs is melted/welded together.
