This is a general question regarding grub.conf. Below is a line from grub.conf. There are two 'root' entries. The first is a "root (hd0,0)". It appears this is the grub directive that tells grub where the kernel and initrd files are located. Is this correct?

The second, "root=/dev/sda2" tells grub where the / partition is located? Is this true?

Finally, is it possible to 'redirect' grub to a second disk? This used to be possible with lilo. One could build a single link to a second disk and lilo would redirect to that disk. The system has a second disk with several bootable images. I would simply tell grub - redirect to disk hd1.

title Fedora Core (2.6.17-1.2174_FC5smp)
root (hd0,0)
kernel /vmlinuz-2.6.17-1.2174_FC5smp ro root=/dev/sda2 rhgb quiet
initrd /initrd-2.6.17-1.2174_FC5smp.img

Yep, close enough.
Grub couldn't care less - unless you happen to have /boot mounted on the same partition. This "root" is actually a kernel parameter that grub is merely passing on.Certainly. (hd0,?) refers to partitions on the first disk, (hd1,?) refers to the second disk, etc.

Plenty of threads here, or check the manual for grub.

Thank you. What would a redirect rule look like? I would like to create an entry for grub to redirect to the second drive and list the boot options from that drive.

Thanks - Dan

Ok so you want to have two grub screens when you boot eg. you boot first grub splash comes up you select entry for second drive then it takes you to the the grub located in second drive MBR. If so then use an entry similar to like it uses for loading windows.

Changing to.
At least I think something like this should work never tried it myself you should be able to test if it will by hitting the c key at the first grub splash then entering.

And you should get your second grub splash.
