This is correct.

If your machine is not 64-bit capable, then the PC will not even boot
the 64-bit Ubuntu CD.

This has *nothing at all* to do with how much memory you have.

Most likely, if you are not getting the GRUB menu at startup, then you
did not install the bootloader correctly or installed it to the wrong
device - e.g. you installed it to the MBR (master boot record) of a
secondary drive (i.e. to /dev/sdb instead of /dev/sda) or you
installed it into the root partitition (e.g. /dev/sda5) and not into
the bootblock of the whole drive (/dev/sda).

I don't know what to say as you do not offer enough information for me
to even take a guess. (I don't know whether you have 1 hard disk or 2;
whether this is a desktop or laptop; how many OSes you have; how many
physical drives you have; how many partitions you have; what type of
partitioning system; what size of drive; what partition layout. Pretty
much anything, in fact.)

Without this, I cannot be more specific, but you might find this useful:
