Grub Error


I have reloaded my webserver because i wanted to make it a NFS as well so i partitioned all the drives and re installed Debian 3.1 Sarge. The problem it is giving an error :

Code:
grub loading please wait....
error 15
And it stops at that

What i did was formatted all my drives hd0 is what has the swap, boot, and root file system. This is on a 6g H/D another H/D (10g) has just /usr and the last drive 200g has /home, /var, and the area for my NFS. I guess with all this reloading and stuff but the learning is not working for me at this time.. Because i am still having the same error after every re-load of the base system.

Any suggestions or anything

PS: I tried re configuring GRUB but i still got the same error. I am still fairly new to the linux OS

PSS: I have a total of 8 partitions thats swap, boot, root, usr, var, home. Spanned throughout three Hard Drives

It seems that grub is looking to the wrong drive. If you have a live cd you can boot from that and find out were your /boot is. Or you just have to keep editing grub with a different drive till you get it.

Mine says;
root (hd0,5)
kernel /boot/vmlinuz root=/dev/hdc6

Grub can get confused and see an old master boot reecord (mbr) and think that is the boot drive when in fact the boot info is on another drive with a new mbr. Try editng grub and changing the drive to hd1 or hd2. If you have an PCI IDE card installed, some kernels are set to look to it first for boot drives. In my fileserver it did this and tried to boot from hd2 when I had installed the OS on a drive attached to the mobo. Changing grub to hd0 fixed it.
When you get it booted, edit /boot/grub/menu.list and make the change to the kernels listed there. Also look for some lines like this;
## default grub root device
## e.g. groot=(hd0,0)
# groot=(hd0,0)
and change it also. This way when you install a new kernel it will not use the wrong hd when grub adds the new kernel to its list.

Yeah i did, I booted up knoppix and the problem still happens the /boot is in the correct grub has the correct path, I even installed everything in one partition and left the other drives in. However i have removed one drive and now it give's me a red screen saying that the cd rom was detected but no valid mirrors found. When i put just one drive and install everything on it it works fine. This is the problem what i am going to do is drop all drives except the 200 and use it soley figure this out later as for now my web server is down and it needs to be back up..
