XP Welcome screen not showing up [XP/Vista dual boot]

On my Lenovo R61 Laptop i have vista and xp installed with EasyBCD installed for dual boot

Everything was working fine for 3-4 days ... but today when i booted xp...it did all the loading and showed the mark moving on boot screen but the welcome screen didn't come...only black blank screen was there

However when i boot in safe mode...it boots properly and shows the welcome screen

But while booting in safe mode....it took 20-30 seconds after showing loading mup.sys....dunno what happens with that...

After safe mode i again started in normal mode but again welcome screen not coming

Kindly help me out

VISTA is working fine

 

If I were you I would do a repair install, presuming you have a retail(full) copy of XP.
