C4507 reboots in rommon

Hi

 

I have a C4507 on which I did a write erase followed by a redundancy reload shelf. I went about configuring however, I forgot to enter username and set logging local on console and had to do reset. 

 

I pulled out the secondary and went about booting the switch from where in i have been in a continuous rommon mode. Once I issue boot bootflash: I would then be in the IOS. I have to do that on both the supervisor engines. Is there any way I can get this to function properly.

 1) Could you check the conf-register value 2) Is there a valid boot image specified in the start-up config ?

Balaji is correct.
A missing boot variable string in the config will instruct the system to boot into ROMMON.

Thank you all for the support.
