Looks like this is true. See attachments.

From maverick the boot drive after update-grub is now hd2
output from chainload:
booting a command list
error: no such partition
Press any key to continue
When I edit the chainload-entry and change "hd2" to i.e. hd1, the output is as
follows:
booting a command list
error: hd1,msdos2 cannot get C/H/S values
Press any key to continue
From the ubuntus grub.cfg both ubuntu and debian are bootable.
kind regards
Gero
