The answer to your question is no, the running nor starting config file will not be affected. The only thing you will have to do is while in ROMMON, is to configure the register usually to 0x2102 (unless your standards use another register)
Just to make it clear. The recovery process consist in accessing the router in privileged mode without knowing the enable password.
To do this, you should change the config-register in rommom mode (the Ctrl Break step) and you change this register, normally to 0x2142, which means: ignore config file in the NVRAM.
When doing that you are able to enter the privileged mode since the enable password is not set, since you have ignored the config file.
You could then list the config file in NVRAN. Just do a show startup.
If you are not using the "service password-encryption" option, neither the enable secret (I mean you are using just the enable password command) you are able to "see" the enable password, and you could continue to use it. Otherwise, you will have to create the password again.
Since you are now in privileg mode you may "copy start runn", enter config mode (conf t) and change you password.
Do not forget to change the config-register back to the usual 0x2102 value:
conf t
config-register 0x2102
exit
