I just ran NAV and it showed that i had two MBR's; well is this correct?

I thought you were mean't to only have the one.

I'm running Windows XP on a 120GB HDD. I just have the one partition...

(Not really a problem as such just wanted to know why i have two MBR's)

From the help file in Norton AV


Although each logical disk has a boot record of its own, there is only one master boot record per hard disk. When starting up from a hard disk, the ROM BIOS bootstrap loads and executes the bootstrap loader in the master boot record before transferring control to a partition's boot record. The reason for this step is that the master boot record specifies which partition is the active partition. Not every partition may contain operating system files, so the system must determine the partition that does.

Boot managers alter the master boot record so that, instead of starting the system automatically, a menu is presented that lets you choose where the system starts from (for example, from a Windows 98 or Windows 2000 partition).

I have no idea what that means.

I know about the menu about which O/S you want to start, but i only have the one O/S.

It means that even though it shows two boot records you only have one.
