Disk "Invalid" after installation next to Windows 8.1

**bio-collector** · May 20th, 2015

I recently attempted installing Ubuntu 15 on my MSI GS60. My configuration of the laptop comes with a 128gb SSD, and a 1TB HDD. I decided to install Ubuntu on a partition on the HDD, and keep Windows 8.1 untouched on the SSD.
Installation worked fine, I setup a swap space and all, and I can boot into both OSs, but the problem is that I can't access my original data on my HDD anymore. I still had data in a partition, and I didn't choose to touch it at all during the installation. When I try to inspect the disk in Windows Disk Manager, here's what it looks like:

It shows the disk as "Invalid" and the disk is not found in File Explorer anymore. (I can only access my C: drive currently through windows.)
On Ubuntu, I can't mount the disk/view due to something about Windows hibernation.

Is there a way I can restore access to this disk in Windows without losing all my data? (I'm fine with re-installing Ubuntu) Alternatively, is there atleast a way I can get data OFF the old partition so I can back it up and re-install Ubuntu while reformating the partition? (If this is the only choice, any help with properly installing Ubuntu for this setup would be greatly appreciated.)

Thanks!

Looks like the hard disk had a Windows specific partitioning called "Dynamic partitions" -- I'm surprised you could even install to it in that case. There is some way to convert to regular partitions I think, search this forum and askubuntu for that. You might try the mount from Ubuntu using the remove_hiberfile option e.g.:
mount -t ntfs-3g -o remove_hiberfile /dev/sda3 /mnt
then you should at least be able mount it and to see the files.

I wasn't able to mount the disk with the command above, but there's a screenshot of the disk information being given off by Ubuntu:

Maybe booting Windows in recovery mode? Can't help much with Windows. If you eventually can see the disk, lookup the way to convert from dynamic partitions to normal partitions.
