I don't know what '"generic" MBR' is either. I was referring to generic MBR
_code_, an optional feature of an openSUSE installation, and I'm sure other
Linux installers. It refers to MBR code that works identically or similarly
to the MBR code included with IBM DOS, MS DOS, OS/2 and Windows versions from
two decades ago, which when installed finds an active primary partition on
the first BIOS HD, if one exists, and transfers control to its PBR if it
does, and prints an error message if a grand total of exactly one active
primary does not exist.

I've never yet used a "live" CD, other than Knoppix, to actually install any
distro. I've always found them to have installation options far too limiting
for compatibility with multiboot systems. Another way to describe the
behavior is that they behave much too much like a Windows installer, making
assumptions that typically interfere with or otherwise damage the ability to
boot or use working installed systems.
