Partitioner and Boot manager hangs!

This is all what happened....
I had opensuse 13.1 Gnome installed...... i messed up with grub2 boot loader for chainloading windows and when i reboot my PC,
it was like this..
Grub loading...
Welcome to GRUB!
ELF header something was written
grub, rescue>


I didn't know what to do so I just installed a fresh copy of opensuse 13.1 on the same drive but this time was the KDE desktop..
Now, whenever I open the Boot loader, it just hangs on 33% [Reading Partitions] and when i open Partitioner... it just hangs on Initializing... :\

Please tell what's the problem and also the solution, in simple :)

Thanks.
