Actually I got this working but eventually was up for nearly 24 hours which meant I was too tired to post back here :-) My Grub is just weird! Which is why I couldn't work things out. For anyone running Fedora 16 or alike this may help; I have this partition layout: 1. FreeBSD UFS2 4. Extended Partition 5. Linux / Ext4 2 Linux Swap 3 Linux JFS Don't ask why 4,5 partitions but Fedora installer took over and left me with no control otherwise Fedora should have been on 2. Now the Grub entry is as follows: menuentry 'FreeBSD 9.0' { insmod part_msdos set root='(hd0,msdos1)' chainloader +1 } I have no idea why my version of grub is sooo different from everyone elses as finding many dualboot bsd/linux combos with Grub entries being more like yours, Bas, this is certainly puzzling. Anyhow the situation is solved :-) Regards, Kaya
