multiboot error in windows : please help

[gemini_shooter]

hi !

I am going to get straight to the point .. I have four operating systems installed on my machine Win XP, Win XP pro, Windows 2003 server and Windows 2000 pro ...... everything worked great a few days ago ... all operating systems could boot .....

but untill recently windows 2003 server cannot boot .... I haven't really done anything to the MBR ... never even touched it ... all I have done is moved some files into to Windows 2003 server installation partation when I was logged in Win XP .... thats it

but everytime I select Windows 2003 server from the boot menu it bounces back ... the screen goes blank for a second as if the OS is about to start then the computer reboots itself and jumps back the boot menu ....

How do I fix this .... Please don't tell me that I have to renistall I have gone through much pain recently .... is there a way I can fix this .... any help would be great.

It sounds like the server is set to automatically restart on error - which brings you back to the menu each time. See if you can select Server 2003 from the menu, then start tapping your F8 key right away & try to enter Safe Mode. If you can do this, then - using RegEdt32 - change the autorestart value in the Registry

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\CrashControl\AutoReboot

Change the "AutoReboot" value to 0 (zero) --- it's likely currently set to 1 (one) [which causes an automatic reboot when the system encounters a fatal error].

It could be that the files you copied over caused a file-version mixup. Whatever the case, if it is an autorestart/error situation, you'll be able to see the error & start troubleshooting from there.

Best of luck
