You can boot in to XP? If so, while in XP does the partition with 8.1 on it show up in "my computer" area? If it does can you access the partition and browse through the files/folders? If you can, then backup/save everything of value....pictures, documents and any software you have installed.

I found these to repair your dual boot setup....not sure if it will work or not but give it a shot.
