I tried installing Ubuntu 12.04 on a HP Mini netbook.
During the installation process I was asked to choose the partition on which Ubuntu would have lived on. I chose the Windows (7) partition and resized it. After the resize there was (still is) an unsable space. I stopped the procedure there and I tried to boot normally through Windows to back-up before proceeding. Unfortunately I wasn't even able to boot into Windows. Using the USB stick with the Ubuntu live version I tried mounting the partition to back-up the files through terminal.
I am not able to mount the partition yet. The process and messages straight from my terminal are listed below.
I am asking for the king assistance of anyone that could help me.
Code:

Is this a wubi install where you are installing Ubuntu inside windows as a program? After resizing, you indicate you "stopped the procedure", what procedure are you referring to? Were you planning to create a new partition on which to install Ubuntu? Are you trying to back up your windows 7 files from sda2? I would be very surprised if windows 7 was on a fat32 partition unless that is some data partition you created?
You didn't actually use uppercase letters for SDA2? is that a typo?
Problem 1: Making a backup is usually the procedure that is done before doing system critical tasks, like installing an OS or re-partition the harddisk.
Problem 2: /dev/sda2 is most likely not your Windows partition, it is most likely a service partition with either manufacturer tools or, more likely, but may be in your case worse, the recovery partition. Windows 7 will not install on FAT partitions. So to backup your files you should try to mount /dev/sda3 instead.
Problem 3: You already have 4 primary partitions (sadly, this setup is nowadays pretty common on Laptops), so you can't add partitions without first to delete a partition and create an extended partition. It may be easier to revert your partitioning and use Wubi or a virtual machine instead.
Problem 4: You can't mount /dev/sda2, which most likely is your recovery partition. This indicates that the filesystem on that partition, making it very difficult to re-install Windows in case your installation is damaged. Unless you have created a Recovery DVD or have a Windows 7 DVD available.
