Show the screen from DMDE from the partitions window view after selecting this disk from physical devices. If the system partition enters the area of the former partition with photos or you think it can be, use a live system, do not use the system from this disk, because each start-up reduces the chances of data recovery and start by switching off the button (download live system CD + DMDE on another PC and run this laptop from it and include the appropriate screen). Delete the letter of the D partition for sure, if the system is smaller than the old system and games together and you know that the partition with photos was the third partition physically on the disk, i.e. the closest to the end of the disk and now it is only in the area of the current D partition. Then you download DMDE on C and attach screen (because you know that your data is in a different physical area and there is no danger of overwriting them). information about the old partition layout proceed as if any write to disk could overwrite your data. After the screening everything will be explained. Generally, it's best to use a live system or connect a second disk to another computer. Working on this system, trying to recover data from it, and having no information about the old partition layout, you are fully aware of the possibility of losing some data. I assume the disk is one and the same.
