Firewall will not boot IOS automatically

I have a Cisco ASA 5500 series firewall. Last week the firewall lost it's IOS. I used my PC as a TFTP server and TFTP'd the IOS file from another 5500 that i have onto the firewall that dropped it's IOS. Now the only problem i have is that it will not boot to the IOS. It goes into ROMMON every time i reload. If i type "boot" in the ROMMON prompt it will boot just fine to the IOS. I have tried the "boot system flash:/asa722-k8.bin" command but it's still not working. I can see the file in a "sho flash" and if i do a "sho version" it says the system image file is "disk0:/asa722-k8.bin", which all seems right. Why wont this thing boot properly?
