I installed Unixware 7.1.1,
After couple of days its taking long time for booting (min. 3 minutes +) while I was trying to authenticate shutdown privileges to users , the system was hanged and when I reset the system it's giving the following error.

FATAL BOOT ERROR : Can't load stage3

I tried ERD's and also tried booting without the emergency diskette
I am able to get the VT0> prompt ,

From here how I can make my system up...

I want the system to be repaired by using ERD's or without the emergency diskette (I don't want to reinstall).

Kindly send me the solution so that I can make my system running.

Thank You
