|What are you using to multi-boot?|
A third party boot manager program,
or - an operating system's built in support?
If you using an operating system's built in support, which operating system did you load (install) last?
In any case, it sounds like the multiboot is working fine, there's probably nothing wrong with boot.ini, and the actual problem is you have a problem with Server 2003 you need to fix.
Try repeatedly pressing F8, don't hold down that key, immediately after you select Server 2003, to see if you can get into the boot choices menu for Server 2003 - if you can, try selecting Safe mode to see if it will then load successfully.
If you do get the boot choices menu for Server 2003, I don't know what your choices are.
If they are the same as for XP, you could also try selecting
- Last Known Good...
- Enable VGA mode - if that works, your problem probably has something to do with the specific video drivers that are are being loaded in normal mode. You can un-install video drivers in Enable VGA mode. Sometimes you can't do that in Safe mode.
- Disable automatic restart on system failiure - if that works, you may then get an error message you can investigate about what un-recoverable error is causing Server 2003 to reboot automatically
If Safe mode works, Enable VGA mode does not, then your problem is caused by something that isn't being loaded in Safe mode that is being loaded in normal mode, but it probably has nothing to do with the specific video drivers that are are being loaded in normal mode.
Disable automatic restart on system failiure only works the one time when you select it from the boot choices menu.
If you want that setting to be on (disabled) all the time, this is how you do that in XP - it may be the same or similar in Server 2003:
"Win XP is set by default to automatically reboot when it encounters an unrecoverable error.
To have XP possibly display an error message you can investigate instead of the computer rebooting:
1. Click Start, and then right-click My Computer.
2. Click Properties.
3. Click the Advanced tab, and then click Settings under Startup and Recovery.
4. Under System failure, click on the small box beside Automatically restart to remove the checkmark.
5. Click OK, and then click OK."
