ntldr

I had Windows XP x64 as my main system, and i also had a second partition with Windows XP x64. Both booted from first partition (C:)

I then installed Windows 7 Ultimate on the first partition. I've added NTLDR using BCDRDIT. I've also copied NTLDR, NTDETECT.COM and BOOT.INI onto the drive where XP remained. However then i try to boot into Windows XP x64 i get

Invalid BOOT.INI file
Booting from c:\windows\
NTDETECT failed

I found instructions on how to fix it using a boot disk, however the partitions are on a software RAID. I've tried to boot from a customized XP CD with the drivers, however it does not offer me a Repair option for some reason - just setup.

Partitions that i have:'=

System Reserved
Main (Windows 7)
Secondary (Windows XP x64)

Here's the contents of my BOOT.INI:

[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(3)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(3)\WINDOWS="Windows XP Professional x64 Edition" /fastdetect

Windows 7 on a 64-bit computer

I read on Wikipedia that Windows 7 on a 64-bit PC needs twice as much RAM as on a 32-bit PC. I understand why is that: every number stored in memory takes 8 bytes rather than just 4. That, in simple terms, means that your amount of RAM is reduced to half when you use Windows 7 on a 64-bit computer… >>> More
