I experienced the same problem on my Acer AS3810T, on Maverick. However, it seems to be fixed in os-prober version >= 1.40 (see last message in the thread for this bug on debian.org, [1]).
I installed the .deb for os-prober (version 1.42) from natty, found here[2], and ran the commands: $ sudo os-prober $ sudo update-grub Now, everything works fine :-) I hope os-prober v1.42 can be backported to maverick.
