A few times I have installed Acronis ( many versions ) and got caught setting up the new MBR installing the Startup Recovery Manager. It was my fault because I didn't know there was already a hidden partiton on the harddrive. This time, I safely deleted the hidden partition and am ready to proceed. One possible thing haunts me. Currently the f11 key will take me to the bios setup. The f1 key does the same. If I install the Startup Recovery Manager and it rewrites the MBR, the last thing I need is a PC that stops dead while booting. So, is there anything I need to do before I proceed to prevent a possible major problem?
