[wellylug] Adding Windows after Linux

[Paul B]

Hi Nathan,
I'm not familiar with the syntax you have used to boot windows although
it looks correct, I have always used (modified for your
disk/partition):
  title Windows
  rootnoverify (hd1,0) #<<<Sets root device without mounting
  makeactive   #<<<Set as active partition
  chainloader  +1

Trawling the grey matter I remember problems booting the Secondary disk
drive. This is back on Windows 2000 or maybe even 98, the same issue
may exist on XP. I've checked the manual and it is still mentioned
under 'some caveats on OS-Specific issues'.

Windows can't boot to a hard disk that is not the first hard disk, grub
provides a method to swap the disk over and make windows happy. Your
configuration would be (something like):
  title Windows
  map (hd0) (hd1)
  map (hd1) (hd0)
  rootnoverify (hd1,0)  <<< I think this is correct, it might need to be
(hd0,0) i.e. where it was swapped to.
  makeactive
  chainloader  +1

NOTE: Take a note of your partition settings before you start. A couple
of weeks ago I configured an XP/Linux system (both on one disk) for
someone and decided to try hide/unhide so they could not blow away
linux partitions from XP. This triggered some code in Grub which
rewrote the partition id's for all linux partitions   every time XP was
booted. Then Linux could not boot until the id's were rewritten. I have
never experienced this using the 'map' command but better safe than
sorry.

Regards
Paul.
