Grub settings!!!!


hii all,
My f10 was working superbly until yesterday nite error 15:file not found occurs.
& with the help of sites like linuxquestions, i gotta hold of my grub,i altered the grub settings & then again i m here.
But the fact i can't digest is how does my grub settings changed--

Before it was like this---

root (hd0,10)

After that i changed it to--

root (hd0,8)

df -h looks like this--

/dev/sda6 2.0G 614M 1.3G 33% /
/dev/sda11 773M 527M 207M 72% /home

tmpfs 500M 1.1M 499M 1% /dev/shm
/dev/sda1 9.8G 2.6G 7.3G 26% /media/disk
/dev/sda5 25G 18G 6.8G 73% /media/New Volume
/dev/sda14 25G 18G 6.8G 73% /media/Edus
/dev/sda15 16G 12G 3.7G 77% /media/disk-1
/dev/sda13 15G 6.5G 8.3G 44% /media/W7
/dev/sda12 40G 29G 11G 73% /media/Miscellaneous
/dev/sr0 6.0G 6.0G 0 100% /media/The Lord Of The Rings

If grub/mbr gets stuffed, there are 2 options:

1. /sbin/grub-install /dev/sda

2. grub
grub> root (hd0,0)
grub> setup hd(0)
quit

noting in the 2nd case that grub counts disks and partitions from 0 (zero)... and always uses 'hd' even if you'd expect 'sd' there...

chrism01,
I have a doubt in your second solution.His /boot directory is /dev/sda9 ,so while installing grub shouldn't the command is grub> root(hd0,8)
grub> setup(hd0)

Yes you are right about the root (hd0,8)

The only way is somehow you have to be changing the menu.lst when booting.

The only way that is if you changed the partitions on the hd or added partitions since installation of grub.
