unable to load FreeBSD 5.2.1 with grub 0.94

Hi FreeBSD-ers,

I've just installed FreeBSD 5.2.1 next to my Debian linux and windows. My first experience with FreeBSD

. Installation went quite fine, except for a scary error on my disk-geometry and some hassle with configuring XFree86. But that's fine now I think.

I decided not to install FreeBSD's bootmanager as I am using Grub to boot linux and windows (actually boot my different linux-kernels and get the grub-command line in the rare case I want to boot windows

). Grub should be able to boot FreeBSD too, so after installation I rebooted, got the grub boot menu, chose the command line:

> root (hd0,2,a)

grub answered "unknown filesystem". When I tried to load the kernel:

> kernel /boot/loader

grub said "unable to mount filesystem".

So now what? I've installed FreeBSD and now I can't boot it. All else still works fine fortunately...

I'm using grub 0.94. I installed FreeBSD on a slice which is, according to linux, the third primary partition. It's located about 30 GB from the start of my harddisk. I only have one IDE harddisk. This is my partition table in the FreeBSD slice (copied from FreeBSD's fdisk):

Part Mount Size NewFS Part
ad0s3a / 256 MB UFS2 Y
ad0s3b swap 486 MB SWAP
ad0s3d /var 256 MB UFS2+S Y
ad0s3e /tmp 256 MB UFS2+S Y
ad0s3f /usr 2737 MB UFS2+S Y

Another solution could be installing the FreeBSD bootloader, but that would only be acceptable if it could boot linux... And still I prefer grub, I'm used to it, it's configuration files are in my main OS (Debian linux) and it easy to configure etc...

I've downloaded the 650 MB iso image. Reinstalling wouldn't be such a bad option, and there are some fixing tools on it too...

Hope anyone can help me, so I can start discovering FreeBSD

.

Greetings,

Corien

Found a way to solve my problem. I've written it down on:

I tried your solution from the other thread and sadly it didn't work for me. What did work was

Code:

title FreeBSD
rootnoverify (hd0,2)
chainloader +1

It took some Googling to find that so I thought I'd take advantage of your thread and post it here for anyone else who might need it.
