cant find the start up disk

13 inch MacBookPro.

Trying to repair from 'grey screen' at start up.

Drive is visible in Disk Repair ... ran and all ok.

Restarts and emergency starts all failing because cant find start up disk.

Restarting from Apple 'On-Line Start up... connected ... ready to go ... but cant find start up disk to chose from.

HI,

Thanks for replying.

I'm just attempting to start the computer. I'm getting the circle with a line through it, then the question mark etc. Following all instructions to repair and re-install but theres never a start up disk to install to

Basically, it looks like the machine can find the start up disk image ... or cant connect to the start up disk. Seems no way out of this, going around in circles.

May need to go to a shop.
