my NC6.2.1 can't be boot.

I installed NC6.2.1 long time ago.and it worked well.
but after i re-install windows XP and linux,i found it can’t be boot.
after detecting EIDE,it was just waiting there and coundn’t get into the system.
i can boot it use safe mode.
what can i do for this?


Does it make a difference if it is a cold boot rather than a warm boot? I have seen machines where windows puts them into a state that QNX only boots from a hard reset (power) and won’t work from a soft reset.
