Hi prudhvi charan,
Is the partion you want to delete a data partion or a system partion? How did you delete them?

If it is a data partion, we can try to use the diskpart command line to have a check. Please open an administrative command line to run the command.
Delete a partition or logical drive(It is also applied to Windows 8.1)

If it is a system partion, I agree with BurrWalnut. We need to boot from a Windows installation media and choose the format option to delete this partion.
