no boot XP after FC4 (REPHRASING OF THE QUESTION)]

Refugio,
As Allan Grant has evidently not responded to your reply with the
subject above, could you please add the next steps to your solution?
Like Alan, I would like to add Linux to a boot manager other than Grub
but my situation is somewhat different.
The boot manager I am using is Boot-it by Terrabyte Unlimited
(http://www.terabyteunlimited.com/). There are instructions on that
website for reconfiguring Linux so that it can be added to the boot
menu. The basic issue is moving Grub to the root directory of the Linux
partition, as you outline is your instructions to Alan Grant.
However, I also have two SCSI drives in my machine and am in the process
swapping the position of one for the other. My machine originally came
with Linux (RedHat Enterprise Workstation v.3) was on the first SCSI
disk and the second one had a Linux partition on it. So Linux took up
the whole first disk. A month ago, I swapped the position of the first
and second drive and installed Windows XP on the new first drive.
I erased the Linux partition on the new first drive and installed a
primary partition for XP (NTFS), an extended partition with two NTFS
volume in it, and Boot-it, which requires a small "EMBR" partition (FAT)
partition. XP works fine. Now I want to add Linux, which is (now) on the
2nd SCSI disk, to Boot-it as a boot item. But the Linux on that disk is
configured to run on a disk that is HD0.
I have tried to (and can) boot my machine to LINUX RESCUE using the
first CD. The next step, I presume, is that I should follow your
instructions below to move Grub on the second disk to the root directory
of the Linux partition on that second drive. Then I must need to
reconfigure Grub (and or Linux) somehow to tell them that Linux is on
HD1 and in what partitions.
What I am not sure about is:
a. What is the name of Linux drive likely to be in this new
configuration? /dev/sda or /dev/sdb?
As I said above, the new drive 0 with XP on it has one primary NTFS
partition and an extended partition with 2 volumes on it.
b. What is the best way to find out which partition on the Linux drive
(the second drive) is the swap partition and which is the Linux
partition? Will fdisk /dev/shX show me this?
c. Once I know this, I should be able to use the,
grub-install /sdXY
command to move Grub to the root partition.
d. Then, what else do I need to do to reconfigure Grub and/or Linux so
that they know that Linux is now on HD1 instead of HD0? I have no clue
about this.
Having done all of this, I would shut down my machine, remove the Linux
CD#1 from my CD drive, and my reboot my machine to Boot-It. The Linux
and swap partitions should then show up in Boot-it. If they do, then I
know how to add Linux to the boot items.
Boot-it's instructions for installing Linux on the boot menu are in
items #1 and #2 here
(http://www.terabyteunlimited.com/kb/category.php?id=20).
Thanks for any help.
