alright, so I manage to know which one is the /boot partition. /dev/sda6 which in grub is hd0,6.
Now, because I used rescuetux disc, the disk recovered the windows 7 OS, so Im able to boot to win 7 from rescuedisk, but it doesnt find Fedora 16. So, at the moment here is how it looks:
Partition Boot Start Sector End Sector # of Sectors Id System
/dev/sda1 2,048 206,847 204,800 de Dell Utility
/dev/sda2 206,848 20,686,847 20,480,000 7 NTFS / exFAT / HPFS
/dev/sda3 * 20,686,848 143,566,847 122,880,000 7 NTFS / exFAT / HPFS
/dev/sda4 143,568,894 505,661,119 362,092,226 f W95 Extended (LBA)
/dev/sda5 338,419,712 505,661,119 167,241,408 7 NTFS / exFAT / HPFS
/dev/sda6 143,572,992 144,596,991 1,024,000 83 Linux
/dev/sda7 144,599,040 338,407,423 193,808,384 8e Linux LVM
this is by using bootinfo website script, by booting from centos live cd that I had spare.
So, now my question is how do I point grub to /dev/sda6.
this is what Im doing so far:
insmod normal (this is by following gnu web site)
then what ???
after I loaded that module and run it, then I just go back to grub>
I tried to re-install grub from live cd after mounting the image by using: chroot /mnt/sysimage ,but grub-install was not found.

initrd (hd0,6)/initramfs same as above.img
then attempts to load the image,but it gets a kernel panic saying: Kernel panic - not syncing: attempted to kill init!
Thanks in advance!

I gave up guys, thanks anyway. I will backup my /home and re-install, also get rid of dual boot, and vbox windows 7. Thanks, I think I ve learned much more of what I knew about grub2;however, I couldnt solve this one. I tried by reinstalling grub2 from rescue cd, grub2-install needed to be run from /sbin/grub2-install. However, even after that nothing.

Righto, after a few more tries, I was able to re-install grub2 to the boot partion, what a world of pain, but plenty of knowledge. Many thanks.
