Multiple boot problems (GRUB) [[SOLVED!!]]

Recently installed PC-BSD 1.4RC sucessfully, but my problem is that not like adding the line of PC-BSD to menu.lst
The command fdisk show me:

$ sudo fdisk -l

Disco /dev/sda: 320.0 GB, 320071851520 bytes
255 cabezas, 63 sectores/pista, 38913 cilindros
Unidades = cilindros de 16065 * 512 = 8225280 bytes

Disposit. Inicio    Comienzo      Fin      Bloques  Id  Sistema

Trying add....root (hd0,1,a) (hd0,2,a) (hd0,3,a) (hd0,4,a) (hd0,5,a) (hd0,6,a) and NOT works.:(

Re: Multiple boot problems (GRUB) [[SOLVED!!]]

Should be simply just hd(0,2) - without the letters I think...

/dev/sda1           hd(0,0)
/dev/sda2           hd(0,1)
/dev/sda3   *      hd(0,2)

and so on...

Re: Multiple boot problems (GRUB) [[SOLVED!!]]

I try root (hd0,2) without letters but NOT works.:(

try to start grub with the --device-map parameter like:

grub --device-map=

then

grub> find /grub/stage1
 (hd0,4)

grub> find /boot/grub/stage1

Error 15: File not found

grub>

will show you the exact name of the partition that contains the grub directory (or the /boot/grub if it not on a separate partition)

That only works to boot linux kernels, and grub doesnt support the bsd filesystem.

Typically bsd (freebsd and obsd do afaik) installs a loader on it's partition start, so you can just chain load:

# BSD
title BSD
rootnoverify (hd0,0)
makeactive
chainloader +1

Fix the rootnoverify to the correct root for your bsd, and it should work a treat.

You are sooooo GREAT James!!:D:)
Solved the problem with adding this lines at final of menu.lst:

title PC-BSD 1.4
rootnoverify (hd0,2)
makeactive
chainloader +1

Many thanxs iphitus!!! Best regards!:D;)
