Good day,

You are booting from Rommon> because you do not have a valid flash file archived in onboard flash or ATA disk. You can use the following steps. You should have a CD with the IOS.

rommon>copy disk0: flash:(flash-filename)
After you succesfully download the the IOS from the ata flash drive to the onboard flash,
