Windows boot question

$

Let me first tell something about history:

 

I still(!) use XP x86 as the primary platform for my developments. I do not like, when e.g. in Win7 Billy the Door always knows better than me, what I want to do.

 

For some test reasons I had to install XP x64 in a different partition. That brought no issue, in the boot menu I could do my choice.

 

For some other test reasons I had to install Win7. After that, in the boot menu, I had the choice between "previous" XP x86 and Win7.

That has been also no problem, because I usually wanted to boot XP x86, not to use x64.

 

Now, in the WinBuilder development, I wanted to check some x64 issues, and tried to reanimate the sleeping XP x64 partition.

 

I used EasyBcd 2.2 to add XP x64 to the boot menu. Result: BSOD

Then I added XP x64 manally to boot.ini. Result: othing new happened.

After some "fishing in the dark", which I cannot exactly remember (sorry !!!) , suddenly my PC booted into XP x64 !!!

 

But it was not longer possible to boot into XP x86.

 

Checking the file system, I found in my primary boot disk a new file ebcd.001 with the contents:

; This boot.ini was automatically generated by NeoSmart Technologies' BootGrabber.exe
; Use EasyBCD from http://neosmart.net/dl.php?id=1 to manage your bootloader

[boot loader]
timeout=15
default=multi(0)disk(0)rdisk(1)partition(2)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(1)partition(2)\WINDOWS="Windows XP on H:\" /fastdetect

And now my current procdere:

When I want to boot into XP x64, I let ebcd.001 untouched.

When I want to boot into XP x86, I rename this file to _ebcd.001.

 

Is there any way to use BCD or an editor to bring the x86 / x64 option into the boot menu?

 

For experts, here some contents:

C:\Boot.ini:
