Never done dual boot partitioned a Windows and Linux system before and to be fair never really ever want to again. The idea is good in principle but if you want to share a common data drive between the two you are going to have to get your hands dirty with sharing permissions between Linux and Windows.
ntfs-3g can mount a Windows ntfs partition happily in Linux, but I ran into trouble when I redirected windows documents, pictures and music folders into Linux and tried to use the same folders there.
Originally I mounted the NTFS volume onto
/home and learned very quickly that this isn’t a good idea. All sorts of issues cropped up about ownership of the
.gnupg folder and keys. I eventually settle on mounting the volume onto
/mnt/data and using symbolic links for David’s Document, Pictures, Downloads and Music folders.
$ cd ~
$ ln -s /mnt/data/david/Documents
I mounted the Windows D: drive in Linux using an entry
UUID=176D74A26CE8F9F7 /mnt/data ntfs-3g auto 0 1
I wanted a seamless user experience so I could create a document or an image file in Windows and use it from the same folder in Linux. I began taking ownership of folders in Windows and then not being able to create files in Linux or vice versa.
Thankfully this was all done for one user so I set about using
The instructions I initially followed used a tool called
ntfsusermap to create a UserMapping file based on results collected scanning a Windows volume. This didn’t turn out so well for me.
I then thought all I need is the users SID from windows right? Let’s just grab it with
c:\> wmic useraccount get name,sid
This churned out a list of all the users and their SID’s which I then ported into a file called
UserMapping in the folder
.NTFS-3G on the root of the filesystem I am sharing – in my case
D:\ which mounts as
/mnt/data in Linux.
I ensured the file created used Unix LF, not Windows CR+LF and ensured I kept the cases exactly
In Windows I then made
david the owner of his
D:\david folder and granted him full control and inherited and overwrote all the permissions below that.
Now when I boot into Linux I can create files in
/home/david/Documents etc. and Windows can read, write and delete them happily.
