SSD migration boot option problem

[lazer100]

I had Ubuntu and Windows XP installed on a magnetic drive.

I decided to reinstall both to solid state drive (SSD),
but wanted to also be able to boot the original versions,
just in case some useful files got forgotten.


I installed XP without problem to the SSD, but 
lost the option to boot to the original Windows XP.

next I installed Ubuntu to the SSD, hoping that this would create
the option to boot to all 4 OS's.

what happened in fact, is that the resulting GRUB boot options
were for both the new SSD Ubuntu and the original magnetic Ubuntu,
as wanted,

but for Windows there is only the option for the magnetic Windows XP,
which I am trying to move away from,



currently the SSD is sda, 
the magnetic drive is sdb,

with the SSD, the partitions are:

volume 1: new Ubuntu32 (8.10 desktop i386)
volume 2: unused
volume 4: logical volume

   volume 5: new Windows XP
   volume 6: unused
   volume 7: Linux Swap partition.


the magnetic drive is:

volume 1: original Windows XP
volume 2: dont know
volume 3: original Ubuntu32
volume 4: logical volume

   volume 5: Linux Swap partition


the file /boot/grub/menu.lst has the entry for Windows,
these are from my handwritten notes so the spacing could be wrong:

title ?????????
root  (hd1,0)
savedefault
map (hd0) (hd1)
map (hd1) (hd0)
chainloader +1

(I'm writing the email from Windows as I want to keep the emails in one
place. but this means I cannot examine the Ubuntu volume as its ext2
which I cannot access in XP)



how do I get the SSD Windows XP to appear in the boot options?

I'm surprised its not there, as its a newer install and its on the first
drive.

also what do these parameters mean? eg (hd1,0), map (hd0) (hd1), chainloader
+1


someone should create a boot program which scans all the drives each time and
supply the boot options, ie a dynamic boot loader, rather than a static one.


they should scan all bootable volumes for all OS's because I have multiple
versions of various OS's.
