problem repairing vista during dual boot xp/vista installation

Hello.
I'm attempting to install xp on a computer that originally only had
vista installed to achieve a dual boot installation where I can choose
between xp and vista.

I'm using the following online guide:

http://apcmag.com/how_to_dual_boot_vista_and_xp_with_vista_installed_first__the_stepbystep_guide.htm

The first steps go fine, I can shrink the vista partition (although I
use gparted instead of the shrink command in diskpart) to make free
space for an xp partition on the same drive. I've made 50 gb available
for xp, which leaves 90 gb for vista. Subsequently I've installed xp
on the new partition and that goes according to plan.
However, when I use the original vista dvd to repair the vista
installation, to ensure the computer boots in vista again (because
after I've installed xp, the computer reboots in xp), I can't repair
the vista installation.
I can select the vista installation to repair it (start up repair),
but it reports no existing problems. However when I reboot, I still
end up in xp.

Does anyone know how to manually ensure the computer boots again from
my original vista installation? So I can resume the guide by
installing EasyBCD to ensure I get a menu when I reboot where I can
choose between the xp and vista installation.

Kind regards and thanks in advance for any suggestions or comments,
Niek

A little searching revealed the following thread:
http://groups.google.nl/group/microsoft.public.windows.vista.general/msg/473de4f9dc1faacf

Vistaboot pro is mentioned there, and that resolved the problem for
me. Now I could boot in vista again. I subsequently could install
easyBCD and now the dual boot works just fine.

Use the bootsect command that is on the Vista DVD to replace the XP
boot sector with the Vista boot sector:

H:\boot>bootsect /nt60 sys
Target volumes will be updated with BOOTMGR compatible bootcode.

C: (\\?\Volume{ad0c894a-e806-11dc-8253-806e6f6e6963})

Successfully updated NTFS filesystem bootcode.

Bootcode was successfully updated on all targeted volumes.
