Dual boot set up question

I installed 2 harddrives both with windows 7 installed in my Asus computer. If I plug them in seperatly they boot/run fine. With both drives plugged into the motheroard the BIOS shows only drive#1 and has only 3 options for boot device order Disc#1, CD/DVD, Removable. I cannnot select the second drive as a boot option. How can I easily choose which drive to boot from, and have the other invisible to the current operating system?

    Hi philisher,
    Does your motherboard support "bios boot selector"?

    My old ASUS board has 3 hard drives connected, each with it's own OS (XP, Vista, Win7). When I boot or reset the computer I can press F8 to bring up a menu that allows me to select which hard drive to boot from. It also allows me to select the CD or a USB device for booting.

    Pressing F8 needs to take place early in the boot cycle. Actually at the same time in the cycle when you would normally press ESC to enter the bios setup menu.

    goodluck

    I've found BootIt NG to be the best money I ever spent for multi-boot OS, and a ton of features to image, backup, format, etc.
