Re: [MLUG] Bootloader install help requested

I know nothing about linux and raid but this is how you get hda to boot 
with grub.  If you do not have a resue disk then find a grub boot disk 
image on the net and write it to a floppy with raw write.  If you can 
not find one then just ask, I will send one to you.  Boot from the 
floppy and at the grub> promt type the following:

kernel (hd0,0) /boot/vmlinuz root=/dev/hda1

If grub says it found the kernel then type this:

initrd (hd0,0) /boot/initrd.img

If grub says this is found then type:

boot

This should start loading your system from the hd.  After it loads and 
you log in as root (or su) then cd to /boot/grub and run the install.  
This will install the grub.

The hd0,0 is grubs way of saying disk 1 partition 1
