your partition map has been affected sadly. I'm amazed you've managed to do it 
within windows 7. oh well... these things happen.

this is however a case for a system recovery job. Either via supplied DVD media 
or if your machine was recent and did not come with the DVD media, it's a 
connect to the internet from EFI firmware.

to do this, try Command R. this should load lion recovery. if it doesn't then 
it should load internet recovery. if not, then it sounds like all you have is a 
windows boot volume.

If you have your recovery CD's to hand, it is time to start using them from 
scratch. at this time, you don't need to do a clean install if the volume can 
still be found by the installer, just install over. this helps repair any 
issues found. 

lIf this doesn't work, email me  with all steps you've taken, your machine 
spec, whether you had it installed with lion as default when purchased or 
upgraded from 10.6, etc and I'll spare some time with you where I can.

I'm kind of in a pickle myself... repairing a powerbook G3 pismo for the 
charity and I don't have a spare G4 or PPC mac to do a specialist restore with 
so am a bit stuffed. DAMN YOU INTEL lol
