If you do not have your data backed up, I would use a program such as Partition Wizard to try to recover the partitions.

Free Download Magic Partition Manager Software - Partition Wizard Online

I would use the bootable version at the bottom of the above link.

Yes it does, but that can often be done in Windows Disk Management.

My drive e has 128gp and c-system drive has 78gp. I tried to shrink the e drive and extend the c drive in disk management but when I tried to shrink the drive it says not enough memory to shrink. I am sure that I selected the space less than it indicated.

Windows Disk Management will not always allow you to shrink as much as you would like.

Use Partition Wizard bootable disk instead.
