Install Windows XP in Dual Boot with Pre-Installed Windows 7

This is preliminary testing work and I'm using Windows 7 Build 6519 and Build 6801 to base these results on. Both these pre-Beta builds create a small separate System partition on which to house the boot system files, bootmgr and the folder Boot. This behavior has only been noted when Windows 7 is the only operating system installed. See the screenshots below. I have not yet been able to verify that Windows 7 Build 7000 behaves in the same way.


Warning that System Partition may be created



System Partition Created



System Partition in Disk Management (no driver letter allocated)



Windows Explorer (System Partition does not appear because no drive letter allocated)



Windows Explorer Installation Drive (No boot system files)



Without allocating a drive letter to the System partition in Windows 7, I used Disk Management to shrink the drive it was on and created a partition of 34 GB on which to install Windows XP Professional.

Windows XP Professional setup saw the small System partition and the first hint that all was not well was that it allocated a drive letter (C:\) to the System partition and changed the drive letter Windows 7 was installed on to D:\




After XP setup completed the file copy process and rebooted, I got this error message:




I then booted to the Windows 7 DVD and selected Repair my computer at the Install now setup screen. Startup Repair had no effect at all and I again got the same "error loading operating system" message on reboot. I rebooted to the Windows 7 DVD and this time selected System Restore from the menu. That was unsuccessful too and on reboot I again got the "error loading operating system" message.




At this point I suspect the problem is caused by NOT allocating a drive letter to the System partition that Windows 7 creates, BEFORE running XP setup. I'll confirm that shortly and then continue with this thread.
