another grub issue
 

I installed bt4 alongside my windows and fedora13 partition, but my fedora won't boot after that, so I updated grub to 1.96, but still fedora13 won't boot, it displays the error, "You need to load the kernel first".
When I try to boot fedora from grub command line,
linux (hd0,6)/boot/<TAB>
it does not show any entry, although my fedora partition is intact with vmlinuz and initramfs inside the /boot directory.
BTW (hd0,6) is my fedora13 partition, file system on fedora13 is ext4, while on bt4 it is ext3.

This is usually a good idea to have a small separate partition for grub, kernels, initrds, formatted as ext2/ext3, mounted as /boot in every system you have installed. Try placing kernel and initrd from fedora to the same partion where current grub config resides and edit grub.conf.
Also, maybe it's not (hdX,Y)/boot/LINUX but (hdX,Y)/LINUX.

I fixed the issue by booting fedora13 live cd and installing the older version of grub, and now it works fine.
As I go to the command prompt for grub, I can find all my kernels in /dev/sda6 using kernel /boot/<TAB> .
The thing I found strange is that it showed nothing when I did the same thing with grub 1.96 on bt, might be because of some issues with grub 1.96.
