My current setup involves a OCZ vertex 120 GB SSD with Windows 8 (label OS) on and and an 1 TB Seagate HDD on which I hold data and the User Profile directory of Windows 8 (label data).
I created free space using Disk Management in Windows on the 1 TB device and booted using the 12.10 Ubuntu USB flash drive.
When asked for the location of the install, I selected the free space I created in the previous step on the 1 TB device and created a new logical partition (label Ubuntu) and a swap partition. The installation went fine with the exception of the GPU lockup that is still occurring on my desktop NVIDIA card. That's another bug that I had in the past with 12.04 and I'm still surprised to have found it on 12.10.
Now although I see my data partition which contains my windows user profiles in Ubuntu, when I boot into Windows it doesn't see it, thus I can't log in (says user profile service could not find profile, obviously because the drive is seen as missing). Starting the repair console in Windows and running DISKPART lists the 1 TB harddrive as "invalid" instead of online.
IS there any way I can make Windows 8 see the data partition once more or will I have to backup my data and reformat it? :/
I am a linux user at work but never had to undergo the process of setting up a dual boot or installing/maintaining ubuntu. I have to say that it is quite frustrating .
Here's an EDIT: I proceeded to reinstall ubuntu without the swap space and with a primary partition on the free space and here is what fdisk -l gives: sdb is the 1 TB hard drive and sdc is the the 120 GB SSD. sda and sdd are removable drives.

(that is a small L) to the question.
