I cannot start my Ubuntu after expanding the harddisk. Installed the Ubuntu 12.04 with 30GB space and I ran out of space, so I used gparted live to expand the disk space. After doing that my partition table got corrupted I guess and I am not able to boot to my environment. VirtualBox keeps crashing, after several attempts, finally Ubuntu boots in read-only mode. I am not sure how to fix this. Please help me.
And I get this error
If I boot into gparted live, I get error
I am stuck doing nothing, I can't work because of this issue. Please help me resolve this.
