This question is somewhat similar to How to use Windows Share has home directory, but in this case Windows is not running.

I have installed a dual-boot configuration with Ubuntu 12.04 and Windows. My Windows partition is mounted on /C. Now I want either Ubuntu to locate home directories in


Which is the location of windows accounts

or I want Windows to use


for home directories. (D is the name of the Ubuntu root directory).

For the first approach, I have managed to create a test user account


The account works but test-user cannot run any X session. From .xsession-errors

chmod: Changing rights on ”/C/Users/test-user/.xsession-errors”: Operation not permitted

Would it help get rid of that chmod, which has no effect? How do I?

If I use the second approach, I need the Ext2fsd driver, which seems to work, but I am not sure if Windows maps the Ext2 system that early.

Here is my fstab

proc            /proc           proc    nodev,noexec,nosuid 0       0
UUID=e7cef061-ed8d-4a82-b708-0c8f4c6f297f /               ext3    errors=remount-ro 0       1
UUID=2CDCEB43DCEB0644 /C              ntfs    defaults,umask=007,gid=46 0       0
UUID=b087b5c0-b4bd-47e7-8d34-48ad9b192328 none            swap    sw              0       0

Update: I found something here: Will work if i do a correct mapping between NT users and Linux users.

Has test-user chowned /C/Users/test-user? And since the drive is shared with Windows, I guess it's NTFS-formatted, right? So have you mounted it with exec permission? otherwise no executable will run from there. – Samik Jul 4 '12 at 9:57
The owner of the entire /C directory is root and ownership cannot be changed. Everyone in the plugdev group (test-user is member of this group) can read, write and execute files on this drive. – user877329 Jul 4 '12 at 11:07
It's a bad idea to have the home directories on a NTFS partition. Windows won't use them as home directories either. If intended for data being exchangable from both systems, I'd rather recommend using a separate drive/partition for that data. For linux specific things better use a file system native to Linux. – Izzy Jul 4 '12 at 11:45
@user877329 ownership cannot be changed because you have not mentioned permissions option in your /etc/fstab. Once you do that (and preferably change the filesystem type to ntfs-3g) the partition will be mounted using standard Linux permission and then you'll be able to chown and chmod each file/directory as normal. – Samik Jul 4 '12 at 11:49
Keep in mint that Linux permissions do not work on non-Linux file systems, NTFS, for example, which means that chmoding and chowning wouldn't make sense. I agree with lzzy, putting home dirs on a non-Linux file system is a bad idea. – mikewhatever Jul 4 '12 at 12:42

Better not to mix home directories.

Home directory in Windows holds activation data - if something goes wrong you have to reactivate Windows !

Software products are creating "hidden" subdirectories in home folder - in Linux and in Windows !

Separate folder for common data is another thing.

I am using ext2fsd but really don't know at what point ext2fsd is available - its implementation is - native driver activated over a service if you use permanent drive mappings.

Better not to mix home directories: Mixing improves my workflow. Home directory in Windows holds activation data - if something goes wrong you have to reactivate Windows !: Then it is better to not map the windows drive at all Software products are creating "hidden" subdirectories in home folder - in Linux and in Windows !: Yes, and some Linux apps ported to Windows will use the same name and therefore the settings will be shared, which is what I want. – user877329 Jul 4 '12 at 14:52

I think the easiest way is to just reroute in Windows (and use ext2fsd):

Also, in any case I will need to reroute "My Documents" because of that ' ', which is not Linux-friendly.

You can change Ubuntu's default documents directory to My Documents by editing ~/.config/user-dirs.dir and changing XDG_DOCUMENTS_DIR="$HOME/Documents" to XDG_DOCUMENTS_DIR="$HOME/My Documents". Although space is troublesome in any system unless used within quote. – Samik Jul 4 '12 at 19:43
But not all applications, including GDB and MinGW, can handle it. So on the Windows side, i do not like this whitespace. – user877329 Jul 5 '12 at 6:53
