When I do it, it goes straight to Mac OS Startup Disk Repair… I badly need a PRAM reset!

Verify that your keyboard works. If it does not then plug in a USB keyboard and hold the same keys on startup.

Ayrton Fineout -

The preferable procedure and hold the keys down until you have heard THREE startup tones.

This is dependant on the age of your MAC.

Very early models have a button switch soldered to the logic board as well.
