This won't work since during booting from a CD-ROM the CD-ROM actually emulates a
floppy drive (wouldn't you believe it?). Some BIOSes in this case display something
like "Your CD-ROM is drive A, your floppy is drive B" during the boot process.
The real problem is that the first sector of a CD-ROM is not an MBR. The bootable part
of a CD-ROM is an otherwise unaccessible session with a layout identical to a boot
floppy.

Correct me if I am wrong, but I thought that booting from the viewpoint
of the BIOS consists in reading the Master Boot Record. In my case
the Master Boot Record contains grub that then picks (depending on my
choice) picks a partition to continuing loading the system (Linux,
Windoze, ...). So what you are saying is that it is not possible to
ask grub to load the system from the CD ROM (hd2) instead of my usual
hard disk (hd0).

I admit that it is a bit paranoid, but I prefer not to have automatic
boot from CD ROMs or floppies as a precaution against viruses.
