Since you are new to linux, I would suggest you look at this link -->
https://www.howtoforge.com/ntfs-disk-recovery
This should help you out recovering data from your windows ??? ( you didn't say ) system.
Basically you will need to boot the system with Puppy, or what ever live CD you choose. Get root privileges, this varies with live systems, so you may have to look at Puppy doc for an answer here.
As root, create a mount point in the linux file system. Done with the mkdir command.
Then as root mount the harddrive partition to the mount point. Once mounted, you can copy files to another media, such as a flash drive. This is the big picture, you will need to do some reading to find the details.
Hope this helps.
