Problem reinstalling GRUB after windows installation

[Flicules]

I have just recently reinstalled my Windows...so it changed the MBR so no GRUB, so i can't boot my Ubuntu
I've read some of the posts but they don't seem to work.The trouble is my 2 WD are in RAID.I've tried to recover GRUB the way it sais here http://ubuntuforums.org/showthread.php?t=224351 and it does not work.

I booted my live CD(8.04) and installed dmraid drivers..

I used the following as in the post:

sudo grub
grub>find /boot/grub/stage1

After this...it sais File not found.
How can i install GRUB?pls help guys.
