It's not working because the boot manager files for Vista are on the XP
drive and because it can't find Vista the boot files are creating a
continuous loop and you can't boot into XP. The boot manager files need to
be removed in order for you to boot back into XP. Maybe the easiest way
would be to refit your Vista drive and then boot as normal. Download the
free application VistaBootPro and install it. Run VistaBootPro and there
should be a tab for bootloader. Click the bootloader tab and then choose to
'uninstall the vista bootloader' This will then remove the Vista boot files.
If you now reboot only XP will be available. After you close down you can
then remove your Vista drive.
After having your pc returned from the repairer then the fun starts.
Re-connect the Vista drive and nothing will work again. To get it to work
you will need your Vista DVD (visit this link on my website:
http://vistasupport.mvps.org/vista_dvd_repair_your_computer_options.htm )
Choose the Startup repair option and this will replace the boot manager
files and you should be able to dual boot once again with XP and Vista.
