CISCO 1700 series IOS ERROR

After a failed Upgrade due to lack of memory on my 1720 router
I decided to go back to the OLD ios which was working perfectly, so I perform:
delete [flashimage]
then tftp the old_image
conf t
no boot system flash [old_flash_image]
boot system flash [New_flash_image]
exit and reload (I don't care for the conf, just my test router)
this is what I got after that:

program load complete, entry point: 0x80008000, size: 0x30b8dc
Self decompressing the image : ############################################################################################################################################################################################################################################################################################################################################################################## [OK]

%SYS-6-READ_BOOTFILE_FAIL: flash:c1700-y-mz.121-27b.bin File read failed -- .

%SYS-6-BOOT_MESSAGES: Messages above this line are from the boot loader.

-----> NOTE <------------
From above the router does a soft boot and load
..... continues normally then:

Press RETURN to get started!

00:00:06: %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0, changed state to up

And all seems to be ok and normal...

I am totally thrown out of sequence here, why would it give me an error the first boot then suddenly do a soft boot and reloads the IOS like nothing ever happen?

I check every where and the only solution says to apply the
no boot system flash [old_flash_image]
boot system flash [New_flash_image]
exit and reload
which I already did, but I still get the same error over and over, the first time the router boots, fails, then by itlself does a soft boot, and like magic all goes normal as if nothing ever happened.

I would appreciate your help..

Maurice.

Are you sure the filename is correct in the boot statement?  Can you post a "dir flash:".  If you only have 1 flash image, you don't need a boot statement as it will boot the only image it has in flash.

Sure JF here's the list:

Router#dir flash:
Directory of flash:/

    1  -rw-     3193336              <no date>  c1700-y-mz.121-27b.bin

And this is the name of the file taken from the root of my tftp:
c1700-y-mz.121-27b.bin

Looks good.  I just tried the same thing and my 1721 double boots also.

I removed the boot statement and it works fine.  You don't need the boot statement if you only have one image in flash:

conf t
no boot system flash c1700-y-mz.121-27b.bin

Give this a shot (fixed mine) if you want to use the boot statement (if multiple images exist):

conf t
boot system flash:c1700-y-mz.121-27b.bin

From Cisco:

Using the boot flash Command

Booting a Cisco 1700 series router with the boot flash command or the boot system flash command results in unpredictable behavior. To work around this problem, be sure to enter a colon (:) following both commands (for example, boot flash: or boot system flash:).

Didn't work, still got the same exact error and behaviour.
Any other thoughts.

I would remove the boot statement.  Do you require it?

no boot system flash c1700-y-mz.121-27b.bin

It worked, sweet .. thanks for the help.
And my apologies for not reading well.
