Phew!   That's a relief! (for me)
I've put this message in my draft and just for kicks, I'll share it with 
you..

*draft*
Extract of http://grub.enbug.org/Grub2LiveCdInstallGuide  :

<extract>
Step Two: Mounting and chroot'ing

Open a Terminal window and type sudo fdisk -l (That's a lowercase L at 
the end).
Now this part can be tricky because you have to figure out which one of 
those listed devices is your linux installation. The easiest way is to 
see which one is listed as Linux, so remember this value. Mine was 
/dev/sda1 and so I will use that as reference in this guide.
If you got a separate /boot partition, you'll have to mount it too.
<end extract>


Javier, I think you have messed up your windows partition as windows 
normally resides in sda1.

chrooting is inherently very risky as you are in root and can do real 
damage. You should be very sure about the partition at sudo fdisk -l 
before you proceed. I myself would not touch chroot.

*undraft*

Javier, if you need me to send you a grub iso,(and you can burn to a cd) 
I'll gladly do so.


Take care, regards  - Goh Lip
