I had a Windows 8.1 installed on C partition of my laptop. I had 2 partitions, C and D. Recently I installed Ubuntu Mate 14.04. but I don't know how to find my files on D partition. Should I mount or something?

Any help would be appreciated...

I think the following information would help :

Unless you've got another physical disk, it looks like you've accidentally overwritten your Windows installation, including both C: and D: partitions.

If you have good backups, now is the time to use them.

If you do not have good backups, shut down and stop using the disk immediately! Your best hope for recovery is to use a tool like PhotoRec, which can recover files from badly damaged filesystems. (I've heard that some Windows tools can do a better job than PhotoRec on NTFS, but I don't remember the specifics or have pointers to these tools.) You'll need a second disk with sufficient capacity to hold your recovered files, and you'll need to boot to an emergency system to run PhotoRec (or whatever you use instead of it).

You need to mount /dev/sda5 to access D: drive.

Best way to do it temporarily is - 

mkdir ~/myDdrive
sudo mount /dev/sda5 ~/myDdrive

To do it permanently, and for all users (and guest), make a /myDdrive (or whatever name you wish) directory in root

sudo mkdir /myDdrive

Then in your /etc/fstab file, add the mount line, that will executed every time, so you always have the drive mounted

/dev/sda5       /myDdrive      ntfs    rw

  • i did the temporarily way, but i got this : mount: unknown filesystem type 'LVM2_member' – Nima Apr 10 '15 at 12:43
  • /dev/sda5 is an LVM partition, not an NTFS partition. – Rod Smith Apr 11 '15 at 01:37
  • @Nima, you are on a different volume group than the one on which your partition is, This article might help http://pissedoffadmins.com/os/mount-unknown-filesystem-type-lvm2_member.html – Arnav Gupta Apr 11 '15 at 19:59
  • The type-0x8e ("Linux LVM") partition type indicates a *Linux* LVM. Windows cannot read that type of LVM, at least not natively, so Windows cannot be installed to it -- at least, not except in a virtualization tool like VirtualBox or QEMU that themselves run atop Linux. Nima's fdisk and blkid outputs indicate that there are no NTFS or FAT partitions on the disk. Being "on a different volume group" has nothing to do with it; they've been *wiped out!* I'm afraid you're barking up the wrong tree, Arnav. – Rod Smith Apr 12 '15 at 16:34
