Improving security using USB?

Hello all,

There’s a project which I’m currently working on. One of my customer wanted a weird thing from me. That is all about preventing OS boot if we don’t have proper USB Flash plugged-in. As I tought I need to copy whole BOOT info (including MBR or BOOT.INI) to USB drive to success this but I’m quite stuck.

I downloaded EasyBCD today but I’m very senseless about that.

Sorry for my bad grammar and I hope someone could help me through this. Anyone who want to share their experience can send me email : aliyalcin AT ymail.com
