Sorry to say so, but from a technical point of view it is a bad idea to configure Linux Mint in such a way that it stores your home folder tree on a Windows partition:
- Windows 8, by default, does not really shutdown completely. Instead it goes into an improved hibernation state.
+ The advantage is that Windows 8 seems to start up much faster than previous Windows versions.
- The disadvantage is that when Windows 8 is in this hibernation state its disk partitions (drives) are not cleanly unmounted.
- Therefore no other operating system must access the Windows disk partitions (drives) in read-write mode.
- If you do you are guaranteed to cause damages to the Windows filesystem on the affected disk partitions (drives).
- Therefore Linux Mint may not be able to mount the Windows disk partition (drive D:) in read-write mode and may mount it read-only instead.
- This way there is a good chance that you will not be able to use your complete home folder tree thus even losing access to your personal Mint settings.
- Windows uses NTFS filesystems, Mint uses EXT4 by default. From a technical point it is not a good idea to put Mint specific things like your home folder on an NTFS partition.
Provided you are prepared to configure Windows 8 in such a way that it
+ really shuts down and does not go to the new hibernation mode
+ does not use fast startup (which in fact is part of the new hibernation mode)
+ so that it will shutdown, cleanly unmount its filesystems and poweroff like previous Windows versions did,
under this condition you may configure Mint to mount the Windows partition which Windows calls drive D: automatically.
You may then use this additional disk partition and store the document files which you create / modify using Libre Office e.g. on that partition.
