Bug#650819 maybe. Should be fixed in beta-4.

Did you get that advice from section 6.3.6.1? I'd agree it is less
helpful than intended.

It's a pity you declined to install GRUB. At least you should have got a
bootable system from which to attempt to get the missing entry into the
GRUB menu.
You could consider a reinstall. Then boot into the new system and run
update-grub
as root.
Alternatively, you could boot the netinst ISO in Rescue mode. From there
you can reinstall GRUB and get a shell to use 'update-grub'.
