"Error loading operating system" after installing Windows XP on separate partition from Windows 7

"Error loading operating system" after installing Windows XP on separate partition from Windows 7 I was trying to install Windows XP on a separate partition from my Windows 7 (RC) installation, but after the first reboot of the Windows XP setup, I get "Error loading operating system" and the system halts.

Windows 7 would have to be the last OS installed. The XP bootloader may be unable to handle Windows 7, but the other way around is likely fine. Try fixing your mbr (/fixmbr) from a Win 7 recovery console.

Windows 7 doesn't play nice with other operating systems on the same box unless they're also Windows 7. So you'll probably have more luck installing Windows XP first, and then putting 7 on another partition (oldest first). I haven't tried this, so it comes with a disclaimer.

Install EasyBCD Free version (bottom of the page) in the OS that is bootable, run easy BCD and repair the Windows 7 bootloader, then add XP back into the Windows 7 bootmanager

"Always it is good to install lower version of the os first, After that you should install Higher version, means xp first then windows 7. if you do the reverse at that time you will get this type of problem. it replace your bootloader.

Because your newer operating system will always recognize and set the required parameters to co exist with the older one.

i dont no how to solve this one, once i also got the same problem."
