Windows 7: Triple boot setup (Linux, Win7, WinXP); XP reports NTLDR missing

Triple boot setup (Linux, Win7, WinXP); XP reports NTLDR missing

After considerable tinkering I've managed to properly partition and install three operating systems in my netbook - Linux Mint Debian Edition, which I use normally; Windows 7, which I use when I need some Windows-specific application that is unavailable in Linux; and Windows XP, which I use (disconnected from the Internet) to interface with some old hardware that has no drivers available for 7 and won't work properly in virtualization.

The last round of tinkering resulted in me finally configuring grub2 properly, so I can now select and boot all three partitions. However, while LMDE and 7 run fine, trying to boot XP results in a "NTLDR is missing" error.

How do I fix this while leaving the rest of the boot procedure untouched? I've tried Googling and applied the found solutions, but they all rewrite the MBR. I can then easily restore grub2, but I lose the ability to boot 7. And if I then restore boot ability to 7 (from the install disc) and re-restore grub2, I again lose XP.

This is a Windows forum. We pioneered many of the fixes for Windows 7, which may not apply here since you are asking about GRUB.

In a typical XP-Windows 7 Dual boot where Windows 7 is installed second the Windows 7 installer only updates the boot files on XP to boot Windows 7. Then to add Linux what works best is here: Dual boot Ubuntu-Win7

Normally to re-establish a failed Windows boot menu what works best is to Mark Win7 Partition Active then run Startup Repair - Run 3 Separate Times. This moves the System flag and boot files to Windows 7 or its' System Reserved partition so the more modern OS is booting the system, and the multi-faceted repair checks and fixes many other parameters.

You can then install EasyBCD to add XP to a Dual Boot. EasyBCD (click Download - no Name or Email required)

However since you're relying on GRUB it may require a Linux solution and not Windows, unless you want to add the Linux distro per Dual boot Ubuntu-Win7.

Another method is here to Dual Boot - Windows 7 and Linux - Windows 7 Forums whose author may be able to help you better if contacted through the comments section.
