i accidentally erased my mac partition

I have a late 2008 MacBook, decided to boot camp with windows 7, everything was fine until I decided I wanted to partition my existing Windows partition which has now corrupted my Mac partition and I have tried everything to get back in. There aren't any important docs or files that I need to recover as I have it all backed up but I really want my Mac OS back! I've tried to use TransMac to make a bootable USB from a Yosemite DMG I got off the pirate bay but that doesn't seem to work. And I can't find a legitimate download link from Apple since I don't have access to another Mac. I have read every forum and help guide I can find out there and nothing seems to work. I have tried holding option and all I get is the Windows boot option, I have tried CMD R, I have tried option CMD R P, I have tried from bootcamp in Windows. If anyone has a link to a usable Yosemite dmg or any advice whatsoever please help, this is the last hope I have.

Thanks in advance

MacBook, OS X Yosemite (10.10.3)

Can you please identify the exact model of MB that you have from How to identify MacBook models - Apple Support ?

Do you have the "Grey" restore disks that came with your MB?

Do not post serial numbers on a public forum.

Can you borrow "grey" disk from someone with the same model? If not, order one of the following from Apple.com.

Boot from the external OSX installation and post the output of the following terminal commands.

diskutil list

diskutil cs list

sudo gpt -vv -r show /dev/disk0

sudo fdisk /dev/disk0

The "sudo" commands will prompt for your password, and it will not be echoed back. You may also see a warning about improper use of "sudo" and potential data loss due to "abuse" of the command.
