[Ilugc] Ubuntu stops working

[asish gaur]

 I installed ubuntu along with windows7 as dual boot.First I unknowingly
deleted  the ubuntu files.
So I installed it once again.now whenever i start it shows two options in
ubuntu
1.Linux 2.6.32-24
2.Linux 2.6.32-24 (generic)
whatever option i choose the system stops working after few minutes
what should i do to make it normal again?
