You won't lose the config as long as you follow all the steps in the procedure ie. from your 2nd link make sure you follow all steps and you will be fine.

If you have modified the running configuration but not written it you will lose that portion but not what is stored in the startup configuration.

1. boot switch and hold button to enable 'Rommon' mode

2. rename flash:config.text to anything but

3. boot switch, will come up as blank switch

4. use command 'more flash:(renamed file)'

5. use command 'copy flash:(renamed file) running-config'

6. remove any username/passwords on device

7. write to memory using 'write mem' or 'copy running-config startup-config'

8. done.
