<p dir="ltr">I think the problem here is that you have the line</p>

<p dir="ltr">in your Barrelfish menu.lst. Try removing that. If that still doesn't work, try with

</span>Did you adapt this menu.lst to refer to the binaries installed on the partition?<br>
<span><br>

</span>How does this entry look like? Is it a multiboot entry? Do you chainload another grub on /dev/sda5?<br>
<br>
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?<br>
