I have tried this:
menuentry “FreeBSD” {
set root=(hd0,3,a) //replace 3 with 4
chainloader +1 //or replace this for freebsd /boot/loader
}

all the possible case I’ve tried, but it also hang on after displaying message “load FreeBSD” .

I have try to entered into grub2, and changed the boot options, then I boot the system, it make no sense at all. when I use “ls (hd0, “, I want to it complete the available partition automatically, but it also hang no after display “partition 4″, somethings like below:

grub> ls (hd0,
(hd0,1) partition 1
linux filesystem ext3
(hd0,2) partition 2
unknow filesystem swap
(hd0,3) partition 3
linux filesystem ext3
(hd0,4) partition 4
[no message at all, hang no here]

that’s the main problem, I think. is it my disk partition error? but I’ve reinstalled freebsd. I am frustrated right now ;-(

Not sure what the problem is… make sure you’ve got your GRUB root for FreeBSD set to (hd0,3,a)

hi, I followed this method you mentioned here, I step by step to edit /etc/grub.d/40_custom, and do update-grub2. then I reboot and select my desired boot freebsd OS, but it can’t boot.

my freebsd os is installed on my disk partition four, on debian its partitions show like below:

debian:/home/user# fdisk -l

Disk /dev/sda: 80.0 GB, 80026361856 bytes
255 heads, 63 sectors/track, 9729 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0×00014522

Device Boot Start End Blocks Id System
/dev/sda1 1 1216 9767488+ 83 Linux
Partition 1 does not end on cylinder boundary.
/dev/sda2 1217 1398 1461915 82 Linux swap / Solaris
Partition 2 does not end on cylinder boundary.
/dev/sda3 1399 6079 37600132+ 83 Linux
Partition 3 does not end on cylinder boundary.
/dev/sda4 * 6080 9730 29321176+ a5 FreeBSD
Partition 4 does not end on cylinder boundary.

what’s wrong with my daulboot system?

grub2 is not fail, it’s much more capable and better organized than grub-legacy. But it’s still new and has some bugs to iron out, at least in Sid.

You can have both grub configs side by side so nothing’s lost.

[...] files they had changed beyond recognition. GRUB 2, it seems, is very different to GRUB 1 More here Make sure you edit the root parameter to the partition where you installed FreeBSD. Remember that [...]

blodgett still think it should be called gubl

Yes, it has customisable splash screens and things. Don’t think the default Debian splash is particularly pretty.

Stefan and I had lots of problems with it when we were setting up the new VDS. Still it has some good features – like I think it will boot off LVM partitions.

i install grub 2. it is foul beyond words to configure and is not pretty at all. it also seems much slower at getting to the menu. grub 2 is FAIL.

ooh! is it pretty?!! blodgett wanted grub2. but new ubuntu puts it only on fresh installs, not upgrades, because it is not sufficiently straightforward to transfer automatically.
sad wanted the pretty.
