Getting to data on Ubuntu partition

[eljc2]

I have been running xubunu, which I installed using the wubi tool, alongside Windows 7.

I tried to upgrade to the latest LTS release of ubuntu, but unfortunately now ubuntu will not load. I am getting a memory error, which I suspect is because the newest version is trying to load up and use more memory. My netbook has a mere 1 GB of RAM.

To solve this, I think I will have to uninstall ubuntu through windows and then I can load it on again using a USB startup disk. However, first, I would like to get access to my data on the ubuntu partition so that I can recover files that were lost. This cannot be accessed through windows. I have tried running xubuntu in trial mode (from the USB stick). However, I don't think every partition is available. Here is what happens when I list the partitions:

xubuntu@xubuntu:~$ lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 298.1G 0 disk
├─sda1 8:1 0 100G 0 part /media/xubuntu/F430478C304754B0
├─sda2 8:2 0 15G 0 part
├─sda3 8:3 0 133.1G 0 part /media/xubuntu/60D85852D8582914
└─sda4 8:4 0 16M 0 part
sdb 8:16 1 7.6G 0 disk
└─sdb1 8:17 1 7.6G 0 part /cdrom
loop0 7:0 0 866.8M 1 loop /rofs

How can I mount everything, so that I can go in and have a look at my documents?

Wubi is deprecated. Don't try using it again. 1GB ram is small for Ubuntu. It may work, but very sluggish. You can indeed better try Xubuntu.

Your wubi-installed Ubuntu system doesn't have a partition of its own. Instead, it has a virtual partition, which is just a file on the Windows system. It is called root.disk and it is very large. You should be able to mount that file in the live session. Have a look here: http://askubuntu.com/questions/243621/how-to-mount-root-disk-from-wubi-when-booted-from-dual-boot-install-of-ubuntu. You may have to change to paths to match your situation. You may have to use sudo.

If your Windows partition with Ubuntu is already mounted


├─sda1 8:1 0 100G 0 part /media/xubuntu/F430478C304754B0
or


├─sda3 8:3 0 133.1G 0 part /media/xubuntu/60D85852D8582914
then assign your Ubuntu to /dev/loop1 (/dev/loop0 is your live system)

sudo losetup -f /media/xubuntu/*/ubuntu/disks/root.disk

make a folder and mount your Ubuntu there:

sudo mkdir /media/xubuntu/wubi
sudo mount /dev/loop1 /media/xubuntu/wubi

Thanks for your help. I managed to get the files and I have not (after a lot of faffing around with partitions), removed the wubi from windows and installed xubuntu fresh from the USB.
