Dual boot option missing
I have Vista and Win 7 dual boot from 2 HDD's. I would get the black and white screen that let me choose which I wanted to boot. I had to reinstall W7 and now that option is no longer their. I booted from the W7 update DVD and when I got to the part of selecting the partion I chose the one that did have 7 on it and formatted it then installed it. Why am I no longer given the dual option and is thier anyway to get it back? I have checked and my files for Vista are all still there.
