(SOLVED) Dual-boot: (Windows 10, Ubuntu 18.04) Can't see files from other OS in shared NTFS partition

Question

I'm quite new on Ubuntu and I'm still learning how Linux works.

My question is simple. But first, I'll give you my context.

I just got a new laptop and added Ubuntu 18.04 LTS to it, alongside Windows 10. I also made a third partition in NTFS, so both OS can share files to each other as needed. I correctly mounted it in my Ubuntu, and I can access it with Windows 10 as well.

However, I cannot see files in Windows 10 I made with Ubuntu. Same thing when I boot with Ubuntu, I cannot see files I created with Windows 10.

The files I created with both OS are .txt files, just to test my shared partition.

How can I see my Ubuntu files on my shared partition when I'm using Windows 10 ? And how can I see my Windows 10 files with Ubuntu in the same shared partition ?

SOLUTION FOUND : I have found what the issue was. Wasn't easy to find but I finally did and it solved my problem. See it here if you have the same problem: Read-only partition, dual boot WIn10

Answer 1

Questioner @Bravo2bad, you have your sample file.txt file lodged into NTFS partitioned disk in Windows 10. Before accessing that file in read-write mode from Ubuntu, you should mark the partition as rw.

Normally, every one will attempt to make an entry in /etc/fstab directly which is considered as normal practice. Nevertheless, for a change, let us do it through GUI to make an entry in to /etc/fstab file and in this process make this GUI method popular!

Open up bash and Search for Disks as shown below:

Click Disks to open up the Software and you select the NTFS partitioned disk of interest. Suppose your target disk is 1 TB having three partitions all with NTFS filesystems.

Assume that it is Warehouse Partition to be made as read-write.

Click the cog icon shown in small redbox and soon after you will face a drop-down menu. Click Edit Mount Options... which will take you to another window where you should enter ,rw as shown in the below screenshot:

Press OK and exit.

Next, create a symlink in /mnt directory as follows:

$ cd /mnt
$ sudo ln -s F6A4656DA46530F3 Warehouse

To issue the following command to verify that the symlink Warehouse was created correctly:

$ ls -l /mnt
drwxrwxrwx 1 root root 4096 May  8 02:31 F6A4656DA46530F3
lrwxrwxrwx 1 root root   16 May  6 11:22 Warehouse -> F6A4656DA46530F3

Now run the following command to make sure that an entry has been made in /etc/fstab file successfully by GUI method:

$ cat /etc/fstab | grep F6A4656DA46530F3
/dev/disk/by-uuid/F6A4656DA46530F3 /mnt/F6A4656DA46530F3 auto nosuid,nodev,nofail,x-gvfs-show,rw 0 0

Now you can access or create any file on this partition from Ubuntu. The created files from Ubuntu on this NTFS partition can be accessed from Windows 10 too.

Answer 2

@Marmayogi Thank you for your answer. You explain me how to do proceed quite well.

But I followed your explainations step by step and here are my results:

512 BG Disk window Mount Options sub-window

Output for $ sudo ln -s F8D42178D4213A70 SharedPartition and ls -l /mnt/ :

total 4
drwxrwxrwx 1 root root 4096 May  9 20:17 F8D42178D4213A70
lrwxrwxrwx 1 root root   16 May 12 22:14 SharedPartition -> F8D42178D4213A70

Output for $ cat /etc/fstab | grep F8D42178D4213A70 :

/dev/disk/by-uuid/F8D42178D4213A70 /mnt/F8D42178D4213A70 auto nosuid,nodev,nofail,x-gvfs-show,rw 0 0

Then I tried to create a new file.txt on the partition.

Output for $ touch /mnt/SharedPartition/fileUbuntu.txt :

touch: cannot touch '/mnt/SharedPartition/fileUbuntu.txt': Read-only file system

So, this didn't solve my issue but thanks for trying anyway. :)

Update : I have found what the issue was. Wasn't easy to find but I finally did and it solved my problem. See it here if you have the same problem: Read-only partition, dual boot WIn10

Your setup is similar to mine:

Notice my UUID, you need to get yours for your shared partition:

Change your /etc/fstab file in Ubuntu

Your Ubuntu+Windows 10 shared partition needs to be setup in Ubuntu's /etc/fstab file so it mounts properly with write permissions:

$ cat /etc/fstab
# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>

Notice the line:

UUID=F2C2ACE4C2ACADF3 /mnt/e    ntfs-3g permissions,locale=en_US.utf8,x-gvfs-show   0       0

• Add (or change) this entry from my UUID to your UUID
• /mnt/e is the artificial location given to Ubuntu when my partition is mounted. You might be more comfortable with /mnt/d if "D:\" is the name Windows 10 gives your shared partition.
• Copy the rest of the line as mine is and hopefully it works ok like mine does.
