This is going to happen even if you don't have Secure Boot. UEFI and
BIOS *do not* have compatible boot systems. You need a UEFI compatible
bootloader like eLILO or a UEFI compatible version of GRUB - which as
far as I know, doesn't ship with Ubuntu by default. Since there have
been workarounds on most systems as of date that allow UEFI systems to
run BIOS bootloaders, such as Boot Camp on Intel Macs or a "BIOS Mode"
on most PC motherboards, it's generally not been necessary to include
a UEFI bootloader with Ubuntu.

But what you need to know is that this probably isn't the Secure Boot
lockout everyone has been worrying about. As far as I know the Windows
7 bootloader isn't signed for Secure Boot (but I could be wrong).
