I want to extend my "C" disk on Windows 10 (second partition from screen below). In order to do this, I plan to move data from disk "D" (fourth partition from screen below) to new partition created from "Unallocated" space that I have right now. Then I'll remove 3rd and 4th partitions and extend size of 2nd one.

Unfortunately there is some problem with creating partition on unallocated space.

Full error:

The selected GPT formatted disk contains a partition which is not of type 'PARTITION_BASIC_DATA_GUID' and is both proceeded and followed by a partition of type 'PARTITION_BASIC_DATA_GUID'

How my partitions look like:

  • I'm somewhat confused as to why Windows considers that to be an error. It ought to be a normal situation... Could you perhaps download gdisk, run gdisk 0:, and post the output of its p command?
