Is there an option to start up using the old config files?
I believe you can do something if you used noobs to set your SD card up but I have never used noobs so can help with that.
the problem is you don't know exactly what is corrupt so fixing it becomes impossible.
the best you can do is created a new SD card with raspbian on it and then using a card reader attached to your pi running the new SD card access your old SD card and copy off any data/programs you have created
As a learnt a long time ago if your work is important to you keep a backup of it and a backup of the backup.
