You've likely removed your OS X partition in the process of doing something you didn't know a thing about. At this point you can try to recover your data.
General File Recovery
If you stop using the drive it's possible to recover deleted files that have not been overwritten by using recovery software such as Data Rescue II, File Salvage or TechTool Pro. Each of the preceding come on bootable CDs to enable usage without risk of writing more data to the hard drive. Two free alternatives are Disk Drill and TestDisk. Look for them and demos at MacUpdate or CNET Downloads. Recovery software usually provide trial versions that enable you to determine if the software would help before actually paying for it. Beyond this or if the drive has completely failed, then you would need to send the drive to a recovery service which is very expensive.
The longer the hard drive remains in use and data are written to it, the greater the risk your deleted files will be overwritten.

I agree I did things which I shouldn't have.
So is that the only option I have To recover my data?
Is there an alternate of copy n pasting the files to external hdd?

If you cannot boot the computer into an operating system, then you'll be hard put to copy files from the HDD. If you could boot Ubuntu you may have an easier time with the Mac formatted volume. Windows cannot read or write a Mac formatted drive.
So your best shot is file recovery software.

A possible long shot;
(1) put the HDD in an external USB enclosure
(2) using another Mac, have a look at the drive using Disk Utility to see if the partition is still physically present, but not mounted
(3) if it is there, try to verify it. That will force it to mount, but it may dismount again if errors are encountered. If that is the case, do another verify and then force quit Disk Utility a few minutes into the verify. That should leave it mounted.
(4) if the partition is still present and you got it to mount (3 above), try looking at it with Disk Warrior. That has an option to recover the drive to a temporary folder on the desktop of the computer you are looking at it from. You can then use that recovered copy to clone to a new HDD (safe method) or back to the old one if you reformat the thing and start over (lose everything on the drive).
After thought, if you have a Time Machine backup, wipe the drive and use that to restore it.

Windows does not believe there are any other Operating Systems. Because of this, it is a terrible guest.
If you use Windows software to modify the Disk Partitions in any way, this clobbers the Mac Partition Map and Mac OS X cannot boot any more.
You should buy a new drive and Install Mac OS X on it and then Rescue your files from the clobbered drive. Data Rescue may be helpful for that.
If you Install onto the old drive before you recover files off it, your files will be gone forever.Mac Pro (Early 2009), Mac OS X (10.6.8), & Server, PPC, & AppleTalk Printers

Just purchase a relatively small USB thumb drive - say 16-32GB - and install the OS on that drive. Then install Data Rescue 3 on the same flash drive. You should be able to boot from it and do both your rescue attempts as well as reinstalling OS X after you've recovered the files you wish to recover.
