Unable to mount

[fedepede21]

Hello
I am a super-noob at Ubuntu.
My Windows-system has broken down and I can't reach my files on the hard drive, because i'm unable to boot Windows.
I am running Linux from the cd, but when I try to open the hard drive, it gives me an error:
'Unable to mount the volume 'C:OS''
Details:
'$LogFile indicates unclean shutdown (0,0). Failed to mount '/dev/sda1': Operation not supported Mount is denied because NTFS is marked to be in use. Choose one action: Choice 1: If you have Windows then disconnect the external devices by clicking on the 'Safely Remove Hardware' icon in the Windows taskbar then shutdown Windows cleanly. Choice 2: If you don't have Windows then you can use the 'force' option for your own responsibility. For example type on the command line: mount -t ntfs-3g /dev/sda1 /media/OS -oforce Or add the option to the relevant row in the /etc/fstab file: /dev/sda1/media/OS ntfs-3g defaults,force 0 0

This details explanation makes no sense to me. NEED HELP!!!

Hi and Welcome !

Execute this

sudo mkdir /media/sda1
sudo mount -t ntfs-3g  /dev/sda1  /media/sda1 -o defaults,umask=0
ls /media/sda1

Post exact error message here, if any.

HI
I opened the 'Terminal' and inserted the code you asked me to insert.
The following appeared:

ubuntu@ubuntu:~$ sudo /media/sda1
sudo: /media/sda1: command not found

ubuntu@ubuntu:~$ sudo mount -t ntfs-3g /dev/sda1 /media/sda1 -o defaults,umask=0

$LogFile indicates unclean shutdown (0, 0)

Mount is denied because NTFS is marked to be in use. Choose one action:

Choice 1: If you have Windows then disconnect the external devices by
clicking on the 'Safely Remove Hardware' icon in the Windows

Choice 2: If you don't have Windows then you can use the 'force' option for
your own responsibility. For example type on the command line:

mount -t ntfs-3g /dev/sda1 /media/sda1 -o force

Or add the option to the relevant row in the /etc/fstab file:

/dev/sda1 /media/sda1 ntfs-3g defaults,force 0 0
ubuntu@ubuntu:~$ ls /media/sda1
ls: /media/sda1: No such file or directory

Try force option now.

sudo mkdir /media/sda1
sudo mount -t ntfs-3g  /dev/sda1  /media/sda1 -o defaults,force,umask=0
ls /media/sda1
