One thing you may try is ctrl-break while it is trying to boot---then you should get the prompt like this...
rommon>
If you still get
boot#
then type
boot#set
and hit enter. You should see something like this...
boot#set
set baud =9600
set data-bits =8
set parity =none
set stop-bits =1
set console-flags =0
set mac-address =0050.7307.C329
set unit-ip =10.200.40.65
set serv-ip =255.255.255.255
set netmask =255.255.252.0
set gate-ip =10.200.40.1
set pkt-timeout =8
set tftp-timeout =16
set boot-action =flash
set file-name ="c800-nsy6-mw.122-10b.bin"
set watchdog =off
set prompt ="boot"
set ios-conf =0x2102
These are all the options that fall under the "set" command.
the "set ios-conf=0x2102" will put the config register at the proper setting for the router to boot the first image that occurs in the router's flash. If it is already at 2102, then you do not have a valid IOS in the flash anymore (power loss and surge that probably occured could have knocked it out and erased it. Sometimes it is possible for the router to need to be power cycled two or three times. If all else fails, one last hope is to reseat the flash module. Good luck.

I was apparently typing between my own posts, while you were replying to the first one...ha ha. Sounds like you can simply set the config register to 2102 by typing
boot#set ios-conf = 102
or
boot#set ios-conf=0x2102
Here is a reference...but this is for password recovery, but it does show you how to change the config register to 2102...on other routers, they boot to the
rommon>
prompt, in which case the command would be
rommon>confreg 0x2102
