After mounting the windows partition is the command prompt (sudo mount -t ntfs /dev/sda2 /media/c) I can't see the document files. The folders shown are Boot, Dell, preload, recovery, sources, system volume info. The other executable files are Autorun/inf, bootmgr, Desktop.ini, Info.exe, Master.log and a bunch of protect.dutch etc. How do you view the files?
Yeah you've chosen the wrong partition. This looks like a generic recovery partition that OEMs stick on new PCs to save them bundling installation CDs.
Use something like Disk Utility, GParted or
sudo fdisk -l | grep '^/dev/sd' to figure out what the real partition number is, then unmount whatever you have on
/media/c now and then try mounting the new choice. You're probably looking for the biggest ntfs partition.
