Is there an MBR on both disks when they are dual booted?  I have a disk failing and it has been my primary. I am concerned about whether or not I will have access to be able to boot into my secondary disk if it completely fails.

There is generally an MBR on each drive.


Save it and run it (Vista & Win 7 right click and Run As Admin).  It will produce a log MBRCheck(date).txt on your desktop.  At the bottom it lists all of the drives it finds and tells you what MBR they have.


However, you will probably need to change the boot order in your BIOS setup for it to  boot from your second drive unless the first drive fails completely..  Right now it looks at the first drive and its boot.ini is where you choose which disk to use.  If the second one is viable you should be able to boot from it now by changing the boot order in your BIOS/CMOS setup.
