Installing Windows XP after Vista in Dual Boot Configuration

[Guest]

I've been running Vista for about a month. I have three partitions on my
hard drive: Vista-160GB, Boot-1.5GB, Free-80GB (I'm running BitLocker). I
want to install XP to the free partition and dual boot. I've tried doing
this previously. As I expected I was unable to boot into vista after
installing XP (the BCD store was deleted). I figured I could boot off of
the vista disk, do a startup repair (which would rewrite the MBR) and boot
into vista. I then used to EasyBCD to make a legacy OS entry in the
bootloader. Everything worked fine. But, after I restarted my computer and
tried to boot into XP, I got a message about "cannot find ntldr"

How do I set up my dual boot without formatting and reinstalling in the
proper order?

You need to be patient enough, if asking for help here, to wait more than 40
minutes for useful responses. What I would suggest would be to repair XP
and run the reenablement of Vista from XP by installing VistaBootPro in
XP as outlined at the end of the series of steps covered here:

( so you know where to go for http://www.vistabootpro.org/ )

It is possible, that with BitLocker enabled, that won't work. If that's so,
either wait for better advice, or remove BitLocker to get the dual boot.

Remove the dual-boot from the vista-loader and use a 3th-party
bootmanager. If you use only primair partitions and 1 drive you
can use my HWBOOT bootmanager. But... it is in Dutch.

Install this. It works in XP or Vista and it's free.
