I know i get the error code because i dont have my windows partition. But i seriously need my vista back. I tried using VMware player but it didn't work
Is there anyway i can restore my windows partition without the installation disc? The restore disc does not work as it needs a windows partition.

Seems to me you answered your own question.
The restore disk needs a windoze partition, you don't have one; you will have to use an install disc.

So there's no other way? Cause Ubuntu does'nt support my game

You could run windoze on a virtual machine inside of ubuntu, or use wine for the game. As far as recovering windoze, I'm afraid you're SOL, you'll have to reinstall.

May i know what it does?
EDIT: I got it already Thanks ALOT!

Also look at CrossOver---they have a version just for games.

Wine does'nt work for Maplestory. thats the game i wanna play. Does CodeWeavers work? I think Wine does'nt work because it has a gameguard

Boot camp helps us create a windows partition right? And when that happens i can use my windows recovery disc if im not wrong. So is there a special version or similar boot camp that will enable me to create a windows partition and is compatible with linux?

EDIT: i checked and it says "Known not to work"
So theres no other way i can play my game? ):
