I recently installed Ubuntu 13.10 alongside Win8. The different Win8 partitions (the main partition, recovery partition and a couple of others) are showing up in Ubuntu. Now I'm wondering if they're supposed to be showing up in Ubuntu in the first place? If I try to enter (mount?) either of these partitions the following, or similar, message applies:

Error mounting /dev/sda4 at /media/jonas/Acer: Command-line `mount -t "ntfs" -o "uhelper=udisks2,nodev,nosuid,uid=1000,gid=1000,dmask=0077,fmask=0177" "/dev/sda4" "/media/jonas/Acer"' exited with non-zero exit status 14: Windows is hibernated, refused to mount.
Failed to mount '/dev/sda4': Operation not permitted
The NTFS partition is in an unsafe state. Please resume and shutdown
Windows fully (no hibernation or fast restarting), or mount the volume
read-only with the 'ro' mount option.

Anything I should worry about?

  • Bootup into windows OS and restart your pc not shutdown.

  • Then bootup into ubuntu os now click on that ntfs partition.The ntfs partition will be mounted and you can able to see all the files in that partition.

You need to disable the "Fast Startup" feature in Windows:

This feature is enabled by default, and it turns shutdown operations into suspend-to-disk operations. The result is an inability to mount shared partitions (if you're lucky) or filesystem corruption (if you're unlucky).

  • I see. But isn't it potentially risky that Ubuntu has access to the Win8 partitions, i.e. if I mess something up my Win8 might go south? Do you think I should disable Fast Startup even if I don't really want access, since there might be a chance of filesystem corruption? – Jonas Fidjeland Nov 24 '13 at 20:51
  • Yes, giving any OS access to any other OS's boot partition does pose some risk from buggy drivers, user error, etc. IMHO, it's best to create a shared-data partition that does not hold any critical OS files. If you don't want to share any data files, you can deny Linux access to Windows by removing the NTFS-3g package or by adjusting /etc/fstab to block mounts. In this case, though, the EFI System Partition (ESP) will still be shared, assuming you're booting in EFI mode, so disabling Fast Startup is still advisable. – Rod Smith Nov 24 '13 at 21:00
  • A shared-data partition sounds like a good idea. If I make one, can I deny Linux access to the other partitions? If I go for not sharing anything, how exactly do I adjust /etc/fstab to block mounts? Yes I think I'm booting in EFI mode, so I'll disable it! – Jonas Fidjeland Nov 24 '13 at 21:38
  • Ironically, you need to create an entry in /etc/fstab for the partition you don't want to mount. Set it to not mount the partition automatically (via the noauto option). See this or any of many other /etc/fstab tutorials for details. – Rod Smith Nov 24 '13 at 22:28
