when I was trying to reinstall oracle 10g it was not installing properly so I restore my windows system 2 days back where oracle 10g was working fine. But after restore windows I look in to oracle home I saw only folders call (1)Application Development and its sub applications (2)configuration and migration tool and its sub applications (3)Integrated management tool and its sub applications (4)Oracle installation products and its sub applications I can't see any database. now I can't create new database or uninstall oracle using universal installer. can you plz tel me what do I do next to ger my oracle 10g back on my laptop.
