OS Selector will no longer load Vista

I have Vista installed for a few months now.
I wanted to dual boot with XP, so I used director to partition the hdd and installed XP to it.
I then re-enabled the OS Selector (I had it enabled before as a test, befire I installed XP)
Both Vista and XP are detected in OS Selector.
But no matter which one I click - XP comes up. I can't get Vista to load anymore.
Please help ASAP as this is my 15 yr old Daughter's laptop and she'll be quite upset

 

UPDATE:

Thru tru image, I deleted the Vista bootmgr and replaced it with a working backup copy I had from a previous image of the same machine. That still didn't work.
I managed to get Vista back tho.
I deleted the new XP partition, but still it wouldn't boot, I couldn't even run DiskDirector or Partition Magic because it kept saying that it couldn't find any HDDs on boot - I was getting worried.
So I deleted the XP part thru the XP install CD.
Luckily, I could boot in with my 2009 tru image and that let me restore a backup copy plus the mbr.

QUESTION:
I want to try this again, but how do I prevent the same problem from happening, namely losing my VISTA boot option?

 

If OSS is correctly booting Vista, you could try the following:

1. Deactivate OSS (don't uninstall). Select Vista as the default OS.
2. Boot the DD CD and use DD to set the XP partition Active and the Vista partition Hidden. Apply the changes.
3. Boot the XP CD and install XP normally.

Once XP is installed and working properly, you need to reactivate OSS. This can be done by installing DD/OSS in XP and reinstalling OSS or by booting to the DD CD and selecting the OSS Activation menu option (in order for this to work, you'll need to have included the OSS programs on the DD CD when you created it).

 

Thx - I'll try those suggestions and post my results here.
Also, how do I ensure that the new XP install goes to the C:\ ?
Last time it installed to E:\

 

well it didn't work. a big problem was that I couldn't load DD FULL from boot because it could never find any HDDs. So I did hid the VISTA in DD safe mode, but then XP wouldn't install on the XP Partition.

I eventually ended up doing this runthru and it worked successfully...

Sorry, but the complete Aronis disk-director-suite 10, build 2161 ("so called vista-ready build) is completely not at all vista-suitable!

- ADDS 10 can't handle new vista partition tables (thus: boot-record)
- ADDS 10 can't handle new vista partitioning-alignment (to reflect new disk-models like SSD-flash disks)
- ADDS10 can't write/correct partitioning-boot-record (PBR) for NT60
- ADDS10 can't write/correct master-boot-record (MBR) for Vista-bootmgr
- OS-selector will end up in not finding any OS on a 2 partition system with 2 independent Vista-installations installed
- Last official build is from 2007-03-14 and no release has been put up to fix all that.
- For all important operations you need a rescue-CD-ROM, while the installed program can't handle by itself changes on partitions, when windows is running (doesn't mind if XP or Vista).

Seems Acronis is just hunting down to take the money from all their customers to deliver nothing.
