Bad MBR on a Latitude D630 - Help?

I have a Latitude D630 running XP Pro SE2 but, ever trying new things, installed OSX on a partition I made on the Hard drive. After installing everything I rebooted only to find neither XP or OSX would boot without using a boot disk. Thinking there was a problem with the boot order I booted into the XP recovery console and did a fixmbr and a fixboot thinking it would fix my problem, but it didn't. Finally I justed deleted the mac partition and resized the xp partition back to how it was hoping xp would still work, but again it didn't.

I've already done chkdsk to ensure the rive was fine and repeated tried the fixmbr command and fixboot but still nothing will work except booting xp off a boot disk.

Any ideas how I can fix this problem? Thanks

 

try bootcfg /rebuild

fixboot

also you cound just do xp repair

 

Already tried that, still nothing. All it did was add 2 copies of the OS to to boot loader when it boots of the boot disk.

The dell did come with a small partition (partition1) that has a diagnostic program, could that throw it off?

 

That's what one can expect from software made by a computer manufacturer named after a piece of fruit.
