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--

I m not getting how does settings changed???
Cud anyone please assist.....

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.

What i'd like to ask is that how does my settings changed??
before changing it to (hd0,8) it was (hd0,10)

could u specify the reason?

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