2 things to make Grub work for you

No matter how better Grub is compared to Lilo, it still has its flaws, making it sometimes hard to use.
Here are two important things to check :

• That you have a “boot” symlink pointing to “.” in your /boot directory. Grub sometimes refer to /boot/boot/.., so it is safer to have this symlink
• That you are having the right “groot” option defined in your menu.lst. It often happens that Grub mappings at boot time are not the same as Linux Grub mappings. For example, you might ask your BIOS to boot on a specific Hard Disk, that is not (hd0). The BIOS will make Grub believe that your (hdX) device is actually (hd0), so your menu.lst will not work. Change your menu.lst accordingly, and re-run update-grub to take the changes into consideration.
