I have done this many times without error if above instructions are followed. BUT... if you have issues as you describe with your keyboard access to your BiOS, the risk is not necessary. I'm sure Hasleo will be able to work this issue without another data point (that may be risky for you).
It's not your BiOS that's at risk for you, it's the BOOTability of your System... your BiOS is not tweaked by any imaging tool. If it's access to your BiOS BOOT options that you need and can't get access to, don't risk it. If you have access to a backup imaging System, you should be fine... if not, you're playing with fire anyway .
