Accidentally formatted my main partition

[DarkRubySage]

I'm not certain if this is the right board for this, so please move this if it isn't.

I have a 500GB hard drive: about 200GB Win 7, 200GB Mint 10(main), 100GB Ubuntu 10.10
Anyway, I was taking openSUSE 11.4 for a spin. I decided it was good enough for an install, so I went through the installer and assigned / to my 100GB partition. it didn't add the 200GB to GRUB, so I did it myself before the install.

Reboot about 15 mins later, there is no GRUB and it goes straight into Win 7. Confused, I booted from a PClinuxOS livecd and look at the partitioning - behold, 200GB and 100GB are not there, and it's just free space.


This is really, really bad. I have months of assignments and a whole archive of isos and the testing image of my Ubuntu Remix that I had promised to my cousin. Guess where all of that is: my apparently gone 200GB main disk.

I know there are ways to recover stuff from formatting, due to the nature of hard disks (deletion is simply telling it there is nothing there), my question is how. I need my stuff, someone please help.

Thanks in advance.


Side note: Notice that weird moment of pure dread when you realize you just deleted absolutely everything?

I'm not sure if there is really "easy way" to undo all that bad things. Maybe you will find your answer here: http://www.linuxdiskrecovery.com/

Live CD. Open terminal
sudo os-prober
hit enter
What do you see ?
If the OS's are still there just
sudo update-grub
hit enter then reboot.

Get a live cd and Download ddrescue. Once you've done that just type "info ddrescue" in a termianl and follow the instructions. Becareful and good luck
