I'm booting from a USB drive and selected the option Try Ubuntu (Ubuntu 13.10). Once it starts, it is showing only 2 partitions, the one where windows is installed and the other as unlabeled (this partition is shown as empty). I have windows installed in C:, D: and F: drives contain my data which are not being shown. I tried the command :

sudo fdisk -l 

and got the following message:

ubuntu@ubuntu:~$ sudo fdisk -l

I have a hard disk of 320 gb capacity, which is shown in this message, but why aren't the other drives( D: and F: ) being displayed?

But sudo fdisk -l command displays all the 4 partitions.You can also look this on gparted partition editor. – Avinash Raj Mar 3 '14 at 8:14
I understood that all 4 partitions are being displayed in this message. I'm asking what can I do about it, how can I access data in those drives? – codeln Mar 3 '14 at 8:18

All the partitions in sda (first hard disk) are SFS (Windows 7 dynamic disks) and they are not supported by Ubuntu (they are encrypted by Windows).

You can convert then to notmal NTFS partitions if you want to use them both in Ubuntu and Windows. Check this question for more information.

I followed the post and it lead to this page:… But when I'm trying to convert dynamic disk to basic disk as mentioned there, it is giving an error stating that it cannot be done. I'm not able to boot into windows so I tried this from a bootable usb. Please help – codeln Mar 3 '14 at 10:39
Ubuntu doesn't understand dynamic disks. You can't repair them from Ubuntu, you will need to use Windows tools. You can try asking for help in a Windows forum, people there could probably help you better. – Javier Rivera Mar 4 '14 at 13:18
