I have Ubuntu 12.10 installed on my pen drive, in order for me to delete certain files of my Windows NTFS drive (I cannot boot in to Windows due to a file in there). However, when I click on the drive in the Ubuntu file explorer, I am greeted with this unfortunate message:
Adding read ACL for uid 9999 to /media/ubuntu failed: Operation not supported
sudo fdisk -l
post back the results , edit your question./media/ubuntu
doesn't sound like the path where Windows would be mounted in linux unless the label on your Windows partition is "ubuntu". It would more likely be/media/748388599828
(A NTFS/FAT UUID) or/media/LOCALDISK
or/media/OS
which are common partition names for Windows
