[ SOLVED ] Still not understanding how to reinstall Grub ?

Question

Hi All
I currently have a dual boot windows 7 & Arch system and i have to wipe the Windows partition and reinstall.  But i am still confused as to how to reinstall Grub once i have reinstalled windows 7.  The wiki post is not longer available and have not found anything that explains what i need to do ... So can anyone point me in the right direction or explain what i need to do ?
Many Thanks

Answer 1

# FLAWLESS GRUB REINSTALL GUIDE BY DARKBEANIES ASSUMING YOU USE EXT3 FILESYSTEM
# Boot arch install cd and login as root, and type the following commands in order, replacing X and Y values with the number of the partition/disk(MAKE SURE YOU GET THIS RIGHT, ASK IF YOU DON'T KNOW)
cd /
mount -t ext3 /dev/sdaX /mnt
mount -t proc proc /mnt/proc
mount -t sysfs sys /mnt/sys
mount -o bind /dev /mnt/dev
chroot /mnt /bin/bash
#IMPORTANT-ONLY IF YOU HAVE SEPARATE BOOT PARTITION
mount -t ext3 /dev/sdaX /boot
#Then try:
grub-install /dev/sdaX
# -WHEN- this fails type this:
grub
root (hdY,X)
setup (hdY)
#Then reboot:
cd /
umount -a
exit
cd /
umount -a
reboot
#That's it!
Why oh why was this page removed from the wiki I do not know...
