When setting up grub, it cant find hd0,3
 

When setting up grub in chapter 8.4 it says to run (inside of grub) root (hd0,3). For me this returns: Error 22: No such partition. According to it, the only partition that exists on hd0 is number 0. In the beginning I set the hdd to what is said in the book, hda1. What i'm wondering is is there any command that you have to do to make the partition table I created a little while ago go into effect?

Hi,

hd0,3 is just an example.

Assuming you only used one partition (if you only mount $LFS, this is the case. If you also mount for example $LFS/boot, it is not the case) you need to substitute the 3 with the appropriate number.

If you used:
- sda1 -> hd0,0
- sda2 -> hd0,1
etc

The first 0 tells grub it is on the first disk. The second number tells which partition (Mind you: it starts counting from 0, not 1!!).

With the info given you probably need to use: root (hd0,0) You also need this in the menu.lst (further on in that chapter).

Hope this helps.
