Respected Sir,

I am having Enterprise Linux on my PC.I have 2 HDDs connected to the PC.Now,Linux is on both the HDDs.But if I want to boot from any one of them then I have to make it as a master and another as slave.So I eagerly want to know whether there is any option for booting the PC from either of the HDD without changing master/slave options of the HDDs everytime before booting.


Waiting for reply.

Depending on the system, you may be able to select your boot device on power on. We generally work with IBM's and HP's, but both of these will give you an option to select the device you want to boot with. I'm not sure if this goes as far as the INDIVIDUAL disks though, and not "disk" general. I can test it out later in the week. Your best option is probably going to be one of those ide selector cards that lets you choose the bootup device. A cheap option is to have a bootmenu on one of the disks that let's you choose the other disk has having the /

Earlier this week I had the same problem.This was my post.It is long post and I ran into various problem.But in the end it was fairly easy to do.

Basically this is the summary:

I added my slave drives distro to my primary distros /grub/grub.conf

I changed the /etc/fstab on my slave to reflect that they are now on the hdb not hda.

I changed /boot/grub/device.map on my slave to include a new device (hd1) /dev/hdb

Finally I had trouble with SELinux not allowing "swapon" to access my /etc/fstab , and I did not have my swap partition "on".You may not even have SEL on yours.

In my thread I posted the exact syntax I had to use.
