Hi guys, I have Pentium D 805 CPU

i have 2 HDDS -

IDE - 40 GB - 4 Partitions - C, D, E, F

SATA - 80 GB - 2 Partitions - I, J

My IDE Drive's C: partition is the Active one.

C - Windows XP SP3
D, E, F - Data

I - data
J - Windows Vista SP1

Now, i have windows WIM image of Win2003 SP2 which works fine in Virtual Box

i booted the pc with PE2 disc and applied the Win2003SP2 wim to I:\ drive

and added the entries of windows 2003 parition in boot.ini of C drive...

and also replaced the ntdetect.com and ntldr from xp ones to win2003sp2 ones

now when i boot xp boots fine, but when i select win 2003 option after 2-3 seconds it restarts.

What may be the problem? Help guys.

Since you have Vista installed, you should probably handle all your boot loader actions with the BCD. Can you still boot Vista?
