I just purchased a hp probook 450 which came with pre-installed Windows 10 pro. I shrank the main partition in order to create a ubuntu partition with dual boot (ubuntu 16.04).

This has worked fine so far, until I tried to mount the main partition of my hard drive. The problem with the mount command is that I cannot determine the FS type of the windows partition. I would expect it is NTFS, but now I don't know for sure.

Thanks to fdisk -l, I know the device file for the partition I want to mount is /dev/nvme0n1p3, but the mount command does not work:

> sudo mount -t ntfs -o nls=utf8,umask=0222 /dev/nvme0n1p3 /win
NTFS signature is missing.
Failed to mount '/dev/nvme0n1p3': Invalid argument
The device '/dev/nvme0n1p3' doesn't seem to have a valid NTFS.
Maybe the wrong device is used? Or the whole disk instead of a
partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around?

I ran multiple commands to try to determine the file system, but without success.

The df does not show the partition I want to mount.

> sudo df -khT

udev           devtmpfs  7.8G     0  7.8G   0% /dev

tmpfs          tmpfs     1.6G   52K  1.6G   1% /run/user/1000

The fdisk command shows all partitions, but does not display the FS type.

The lsblk command shows no FSTYPE for the partition I want to access.

Can anybody help me in mounting this partition ?

Thank you all for your answers. I tried them but it still didn't work. However, while looking at the disks utility in Windows, I noticed something that came out of my mind while installing: the disk is actually encrypted with bitlocker.

This is the reason why lsblk was not able to show the FS type. So, I went to this post and was able to decrypt and mount my Windows drive.

I seem to recall that shutting down Windows 10 hibernates while a reboot does not. Try to access the partition after a Windows 10 reboot. If that fails you will need to disable fast startup.

  • Type Control Panel in the search box

  • Click Control Panel.

  • Click Power Options.

  • Click Choose what the power buttons do

  • Click Change settings that are currently unavailable.

  • Scroll down to Shutdown settings and uncheck Turn on fast startup.

  • Click Save changes.

Incidentally, using Disks or Gparted (within Ubuntu) to view the disk and partitions will confirm the FS type. FS location

If it's not ntfs you could try msdos.

man fs

msdos    is the filesystem used by DOS, Windows, and some OS/2 computers. msdos 
         filenames can be no longer than 8 characters, followed by an optional 
         period and 3 character extension.

Please try exFat. Looks like that's a possibility based on the following page in wikipedia.

https://en.wikipedia.org/wiki/Microsoft_basic_data_partition

When I try it on my computer, it uses a FUSE module.

$ sudo mount /dev/sda1 /mnt/hdd
FUSE exfat 1.2.5

UPDATE: This site has a great article on exFAT in ubuntu. It's from 2015, but it might help.
