I had a working version of Ubuntu on my hp stream 13, and in my own stupidity I tried to repair the windows installation from EFI file and a recovery disk. I stopped before it advanced a lot, but now I have a partition with all my data which I cannot use because it says "basic data partition" and content "unknown".

I hoped I can reboot the system in that HD partition but the grub repair answers I found did not work. Is there any way I can recover the data stored there? I tried already several programs which did nothing like reinstalling grub, testdisk, gdisk...

I learnt the lesson. Do not touch OS before saving important data.

I hope you can help. Thanks!

Manually mount the filesystem in read only mode.

Check to see if you have a mount point (folder for mounting your partition in) for your Windows partition in the folder /media using this command:

ls /media

If you don't see a folder for your Windows partition, you should create one with the following command:

sudo mkdir /media/windows

Next, mount the partition in read-only mode onto this folder with this command:

mount -t ntfs-3g -o ro /dev/sda3 /media/windows

Note that you should change /media/windows if your mountpoint is called something else. Now you will be able to view/open files on your Windows partition using any program in Ubuntu. However you will not be able to write to the partition or modify any files as it is in read only mode.That way you will recover your data

Just to add more information to my input. I did not find any way to mount this partition. I am thinking on installing grub in this partition and hope it becomes bootable, but I did not want to write anything on the disk before I could get an answer about mounting it. Is there any way to "force" mount making the system to "believe" is a ext3/ext4 partition?
