What age is the house? If relatively modern, sometimes you can see the metal lintel above the window head on the outside, though this is no guarantee it will also be metal inside.

I'm having a similar problem myself at the moment. Putting some blinds up in the kitchen, first window went without a hitch because it was a full width blind and I was side mounting the brackets.
Second window I am having to top mount the brackets as the blind isn't quite full width (tiles come half way up the window). I've hit the concrete lintel and realised my drill bits aren't up to it.
Based on the 5* reviews, I've just bought a set of these and will be having another go at it today...

Trouble is, the one I'm now trying to fit is directly above the kitchen sink so I'm limited where I can stand to get good leverage to give it a bit of "oink".
I'll go in with the smallest one first, see if I can get a guide hole going and then attack it with a bigger one...
Fingers crossed.
Ryobi hammer drill. Fully chargedit is also interesting to know what electric drill you have.
Update: I admitted defeat in the end and got a handyman to come round to help, it was concrete lintel and he managed to get through it with an SDS drill.
