Did you adapt this menu.lst to refer to the binaries installed on the partition?

> 4- In the main menu.lst file under /boot/grub/menu.lst I added a new entry for Barrelfish and rerun grub
How does this entry look like? Is it a multiboot entry? Do you chainload another grub on /dev/sda5?

Can you post a copy of all the menu.lst files involved in your setup, as well as the *exact* location of the Barrelfish binaries?

Best,
