Background: i began with a single partition ~72MB, with Zorin OS 6 installed. Yesterday I was following these instructions to move my /home folder to a separate partition. After partitioning (Original partition - ~39MB, New partition - ~33MB), however, whenever I try to boot to my Zorin 6 installation, I receive a black screen and "could not write bytes: Broken pipe", along with other, varying stuff. I continued to follow those instructions from a liveUSB of Xubuntu 12.10. It was getting too complicated, however, so I just moved the files I wanted to keep onto the new partition using
gksu thunar, and booted into my liveUSB to install Xubuntu 12.10 over Zorin.
I started the installer after choosing "Try Xubuntu without installing", and when it came to the option on how to partition, I chose "install over Zorin 6", and checked the "Use LVM" option. Then I clicked forward, but some error came up. (I can't really remember, I started to panic shortly after this) When I closed out of the installer and opened gParted to see what had happened, I saw that I had two partitions - a 255MB ext4, and a new 72 GB "unknown" partition, with a flag of "LVM". When I tried to mount the 33 GB partition still listed on my desktop, it was unable to - it received some error of "not enough space".
This is where I really started getting frantic - I tried to open the installer again, it wouldn't, so I shut down, and rebooted the liveUSB. This time choosing "Install Xubuntu" - I followed the same steps, and resigned myself that I lost the data, but after selecting the option to erase the whole disk and install. Immediately after it said that the installer had encountered an unrecoverable error; it was going to boot a live desktop so I can see what went wrong and/or to try the installer again. Afterwards it just stayed on a black screen. To wrap it up, I have three partitions:
- ~255MB, type "unknown", no flags
- ~72 GB, type "ext4", flag "LVM"
- Linux Swap
Question: Is there any way I can recover my data without being able to boot the installed OS?
I have a considerable amount of music, game data, etc. that I would really not want to lose, so any help is appreciated.
