Boiler Pressure Help Please

Afternoon all.
I've not long moved into my rented house with a combi boiler. All was working well and when I put the heating on had no problems other than needing to bleed the radiators.
Today my boiler made quiet a long moaning high pitch noise and now won't fire up. The pressure gauge on the boiler is at 0 but there's a separate pressure gauge in the cupboard at 5. I've let some water out of a radiator and the high one didn't budge. I can't see a valve on the boiler to increase pressure so I'm guessing the high one is the actual pressure?
I have read that to reduce pressure to let some water out. I hope that's all that's going on here and advice/reassurance would be very welcomed.

I have no idea what the pressure gauge in the cupboard would be, but the one on the boiler should normally read 1, or 1.5 if that's what it says in the owners' manual. A lot of them have a green zone that the needle should be in when cold.
Normally there's a filling loop, via a flexible pipe with a valve on each end, to re-pressurise the boiler. This could be on the pipework below the boiler, or possibly tucked up inside the bottom of the boiler on more modern ones.
Turn one valve on, then slowly turn the other on to re-pressurise. Turn both off again when done.If it sticks, force it.
If it breaks, well it wasn't working right anyway.0 -

Make and model of the boiler?

If it is a rented place, ring the landlord and get them to sort it out - their problem0
