Comment 4 for bug 690253

It tried to modify the boot.ini on C: (didn't report an error), then tried on F:. I don't think it's unusual to look for all the boot.ini's it can find. Right or wrong, I've noticed it modifies the one on my rescue partition as well.
Regarding the missing entry in c:\boot.ini, maybe it's tripping over that [spybotsd] stuff. I've never seen that before. Just add the required entry yourself as a workaround while you're waiting for someone to fix the bug.
