Righto, I'm sorry I was away this weekend and unable to help.
Basically it's saying there's a corruption in the window's startup. For those saying plug another hard drive in via usb ? If the machine doesn't boot into windows, how can you access the drive ?? You won't be able to access the drive now will you ? And, unless the drive is formatted in fat32, dos is pretty much out of the question
Give me 5 mins or so and I will provide you 1 of the 2 available options to you
