Ubuntu just wiped the entire hard drive after selecting reinstall ubuntu option. I thought it would re-install in the same partition where ubuntu was previously installed. Now I don't know what to do, can I still recover my files on the other partition. If so, how? Please help I have some important files in there.

"Please help I have some important files in there." If files are important you make backups. Especially when messing with operating systems. Otherwise you can probably forget about those files. There is a tool called "testdisk" you might try. – Rinzwind May 09 '14 at 14:02

Also this has a working solution it seems: http://askubuntu.com/questions/436031/how-can-i-recover-my-data-after-formatting-ubuntu-with-ubuntu?rq=1 – Rinzwind May 09 '14 at 14:03

The data recovery process of partial files requires a professional forensic support if the file is very important.
If the file is not very important (ex. it's not a bank code) you can try to use Open Source software like PhotoRec Digital Picture and File Recovery which is a friendly and unobtrusive alternative to TestDisk.
To start the RECOVERY procedure on your Linux system follow the Official PhotoRec guide.
Always make backups of your data before and after using any file recovery tool.
Every time you or the system write on the HD/SSD a deleted chunk of file may be overwritten; after 7 overwrites many files will not be recoverable without forensic support.
NOTE: do not recover your files on the partition where you previously deleted them.
To backup your personal files use any application from the repository; to backup your system use professional Open Source tools like Relax-and-Recover. Do not make backups on USB media, use a DVD or a cloud-based system (I suggest Ubuntu Cloud partners for an Open solution).
