[Joy Methew]

hello all,

I have installed Windows xp on a seperat hard drive(on sda).  I installed
the new hard drive and then installed Redhat linux 5 on the new drive(hda).
 i set the prority on other(xp) bydefault.
redhat is running fine but when i enter on other it`s not running.
i m sending out put of "fdisk -l" and grub.conf.
