i want to install windows server 2003 and windows xp on same hard disk and on same partition drive. is that possible ?? please help me out if anybody know about this

If you are going to dual boot, I'd recommend using at least 2 partitions. I would use 3 partitions, one for XP, one for Server 2003, and one for shared data. -- Mike Burr

you mean to say i can't install xp and server 2003 on same partition on same HDD

No, because the boot process references only the partition to start from, so installing both would likely cause the final one to be installed to win during the boot process and if it did not fail during the install, the first installed one would be moved to a directory called Windows.old or something like that. -- Mike Burr
