I have been researching a way to add the new Microsoft offline security scanner to the bootloader on windows 7. Allow security scanner to be used when a machine is possibly infected. Visual BCD may do it. I was wondering if anyone has accomplished this as yet?

Boot Loader (thanks AslVG)

I hate when people ask me "why" I want to do something this way, but I can't help myself - sorry. Wouldn't it be a lot safer to boot from a non-writable live cd in case of an infected machine/disk? And to your question - you can certainly create another boot partition and do this. You could perhaps build it with BartPE and add the tool you want there. problem is the scanner changes all the time. How would you keep it current? –  uSlackr Feb 8 '12 at 23:50
    
good point. yes typically you could load it via usb or livecd. usb allows for the updates that the tool can do. So the updates is the cool feature. you could boot into the tool and get updates via wireless or wired connection and then run the tool locally. –  mikedopp Feb 8 '12 at 23:58
    
However you do have a good point about a hard drive being infected. I guess it would depend on the situation but it might be a useful tool to have handy. just sayin' –  mikedopp Feb 8 '12 at 23:59

The whole point of an offline security scanner is to be (oddly enough) offline. You could probably create a vhd and add an entry with bcdedit (or visualbcd), or a separate partition and add a boot entry but from an infection standpoint I wouldn't consider it trustworthy.
