For this you will need the trivet from your Instant Pot, or a metal grille to sit your potatoes out of the water needed for the pressure cooking.
Make sure you wash the potatoes thoroughly. I remove eyes to please fussy teenagers, which is why I have some white spots where I've removed them on my potatoes.
Put the trivet or metal rack on the bottom of the pan, and sit the potatoes on top.
Put on the lid and slide the valve to the sealed position on the lid.
With an Instant Pot, select manual, and adust the time to suit your needs. My cook time for the future for these, will be set at 35 minutes on high.
If you can, wait for the natural release to happen for the pressure from the cooker, but if you are in a hurry, protect your hands and slide the valve on the lid to the release setting.
Remove the potatoes and serve with your choice of toppping. Here, we simply use butter and coleslaw.
