Deleting a partition will only erase all the data on it.

Besides erasing all your data on the partition, your Windows will also mark the spare space as unallocated space. However, the data on that partition could still be present and recoverable with reliable software since the system only recognizes the partition as free space after this action. In other words, Windows only hides the data on it.

Note: If you have any important data on that partition and you don't want to go through the complex recovery procedure, you'd better back them up or clone the partition before the task.

Generally speaking, deleting a partition won't cause data loss on other partitions, but if you operate incorrectly, there might be a chance you will lose your data on other drives or even cause worse issues. Thus, I recommend using partition manager software free to delete a partition safely and easily without any risks.
