I have a little problem. I installed Ubuntu Linux 5.1 on my IDE drive (/dev/hdc1) and it works fine with GRUB. But now I want to use a adapter so I can use SATA interface on the motherboard. The problem is that that will also change the drive location to /media/sda1 and the system will not boot. How can I configure GRUB to boot from SATA instead of the IDE interface? Do I have to make any changes to my Ubuntu installation?

To my understanding there are a couple of files that you will need to change. The first is grub.conf. Anything associated with /dev/hdc1 will have to be changed to the location of your new hard drive (I'm not sure /media/sda1 is the correct mount point, make sure you check into that. The second file that will most likely need to be changed is /etc/fstab. At the moment it probably lists all your mount points with respect to /dev/hdc1 and this will have to be changed to the new mount points.

This will probably need to be done using a boot/Live CD of some sort so you can mount the partitions and edit the necessary files. To my knowledge I can not think of anything else to do, but someone else please ante up if I forgot something

We would need more info to help you like how many drives are in the system, where is grub installed on (which hard drive and what is the boot order) and the output of sudo fdisk -l and your /boot/grub/menu.lst would be nice to see as well.

Ok, I solved the problem. It was not that complicated. The only thing to do was to add a new menu item in menu.lst with root=/dev/sda1 instead of /dev/hdc1 then run grub-install /dev/sda.

A note is that the drive appears as /media/sda in Ubuntu but the real mount point is /dev/sda..
