I also observed the message "error: fd0 read error." on my intel core duo laptop. I was also able to make it go away by disabling legacy FDD emulation in the BIOS. (In my Toshiba QOSMIO BIOS, the entry is "USB-FDD Legacy Emulation". No floppy is connected.)
I confirmed that the message was being generated by grub2 by changing the message string in disk/i386/pc/biosdisk.c and observing that the message changed.
The presence of the message does not appear to delay or interfere with the presentation of the grub2 menu, which appears shortly afterward, and from which booting proceeds normally.
